Top 3 Picks for Best Faraday Cages for Electronics Storage (June 2026)

Best Faraday Cages for Electronics Storage in 2026

1. lanpard Faraday Pouch for Car Keys – Best Budget Key Fob Protector

I have used the lanpard Faraday Pouch for about six months now, and it has become my go-to recommendation for anyone who just needs simple car key protection. The pouch slips right into my pocket alongside my keys, and I can confirm from multiple phone-call tests that it completely blocks all signals. The carbon fiber exterior has held up well against daily wear, and the zinc alloy hook makes it easy to attach to a keychain or bag.

What surprised me most is the build quality at this price point. The double military-grade RF shielding cloth genuinely works. I placed my phone inside, called it from another device, and the call went straight to voicemail every single time. For under ten dollars, getting two pouches is hard to beat.

The main thing to watch out for is fitment. These pouches measure 3.15 x 4.5 inches, which works perfectly for standard key fobs, but oversized fobs from luxury vehicles might be a tight squeeze. I also noticed that after months of daily opening and closing, the edges start to show minor fraying. Nothing that affects performance, but worth knowing if you plan to use one pouch heavily every day.

The lifetime warranty gives peace of mind, and having a second pouch means you can protect two vehicles or keep one as a backup. For anyone who just needs key fob protection without spending more, this is the one to get.

Who should buy this

If you own a keyless-entry vehicle and want affordable, proven protection against relay theft, this 2-pack is exactly what you need. It is also great for people who want to keep a spare pouch in a gym bag or travel kit for occasional use.

Anyone on a tight budget who still wants military-grade RF shielding will find excellent value here. The signal blocking is verified by thousands of positive user reviews, and the compact size means you will actually use it daily.

Who should skip this

If you need to protect devices larger than a key fob, like phones or tablets, look at the larger bags in our list. These pouches are specifically designed for car keys and small items. Also, if you want something that looks premium sitting on a counter at home, a dedicated Faraday box might suit you better.

People who want EMP-level certified protection should consider the Mission Darkness options instead. While the lanpard blocks RF signals effectively, it does not carry MIL-STD certification.

2. XIAODUN Military Grade Faraday Bag – Best Fireproof Signal Blocker

The XIAODUN Faraday Bag caught my attention because it combines three layers of protection that most competitors do not offer in one package: signal blocking, fireproofing, and waterproofing. At 7.5 x 4.7 inches, it fits most smartphones comfortably along with a key fob or two. I tested it with my phone and was impressed that it blocked every signal type, including 5G, which some cheaper bags struggle with.

The flame-retardant fabric is a feature I did not know I needed until I thought about storing backup electronics near potential heat sources. The waterproofing held up when I accidentally left it out during a rainstorm. The detachable wrist strap is a small but thoughtful addition that makes it easy to carry without fumbling.

On the downside, the Velcro closure is quite strong, which is great for sealing but means it takes a moment to open. If you need quick access to your phone regularly, this could become annoying. The bag is also a bit bulky to slip into tight jeans pockets, though it works fine in jacket pockets and bags.

For the price, this is one of the most well-rounded Faraday bags I have tested. It handles phones, key fobs, and small electronics with equal effectiveness, and the added fireproof and waterproof layers give real peace of mind for long-term storage.

Who should buy this

People who want a single bag that can handle both daily phone protection and emergency storage scenarios will love this. The fireproof and waterproof features make it suitable for storing backup electronics in a bug-out bag or emergency kit.

Anyone who travels frequently and wants anti-tracking protection for their phone will appreciate the wrist strap and compact form factor. It works well as an everyday carry item that doubles as emergency gear.

Who should skip this

If you primarily need car key protection and nothing else, the smaller lanpard pouches are more convenient and less expensive. This bag is better suited for people who need phone-sized protection with extra durability features.

Those looking for MIL-STD certified EMP protection should look at the Mission Darkness products below. While the XIAODUN blocks signals well, it does not carry military certification for EMP-level events.

3. WHonor Faraday Box for Car Keys – Best Large Capacity Key Safe

The WHonor Faraday Box solved a problem I did not realize I had: managing multiple key fobs in one place. With a family of four drivers, we needed somewhere to store all our key fobs securely at night. This box holds up to 15 keys comfortably, plus phones and cards, all inside a signal-blocking enclosure that looks great on an entryway table.

The aircraft-grade ABS construction feels genuinely solid. I dropped it from counter height onto tile flooring and there was not a scratch. The dual-layer military-grade fabric inside blocks all signals completely. I tested every key fob inside the box, and none of them could communicate with their vehicles through the walls.

The velvet-lined interior is a nice touch that prevents keys from scratching against each other. The metal lock adds a physical security layer on top of the signal protection. At 4.8 stars with 84% five-star reviews, it is clear that other users are having the same positive experience I did.

The main trade-off is size and weight. This is not something you toss in a pocket. It is designed to sit in one place as a home storage solution. If you need portable protection, a bag-style option would be more practical. But for a household with multiple vehicles, this is hands-down the best Faraday cage for electronics storage at home.

Who should buy this

Families with multiple vehicles and keyless entry systems will benefit most from this box. It eliminates the need for individual pouches by keeping all keys in one secure, signal-blocked location. It also works well for small offices or businesses that need to secure multiple key fobs overnight.

Anyone who wants a Faraday solution that doubles as an attractive home accessory will appreciate the sleek design and velvet interior. It looks nothing like tactical gear, which makes it blend into any room.

Who should skip this

If you need portable signal protection for carrying with you during the day, this box stays at home. The weight and size make it impractical for travel. Consider one of the bag or pouch options instead for on-the-go use.

Those on a very tight budget might find the smaller pouches more cost-effective, especially if they only have one or two key fobs to protect.

4. briidea Faraday Box Key Fob Protector – Best Stylish Home Storage

The briidea Faraday Box strikes a balance between the compact pouches and the larger WHonor box. It holds 5 to 8 key sets in a sleek PU leather enclosure that looks right at home on a console table or kitchen counter. The faux leather finish is surprisingly convincing, and guests often assume it is a regular decorative box rather than a signal-blocking safe.

Signal blocking performance is solid. I tested it with my key fob pressed right against the car door, and the vehicle would not unlock with the fob inside the closed box. The premium RF shielding material inside does its job consistently. With over 7,800 reviews and a 4.6-star rating, the user consensus backs up my experience.

One thing I noticed is that the buckle closure, while secure, feels like it could loosen after years of daily use. It is not a dealbreaker, but something to be aware of. Also, the lid does not stay open on its own, so you need one hand to hold it while grabbing keys with the other. These are minor quality-of-life issues that do not affect the core signal blocking function.

The lightweight design makes it easy to move between rooms if needed. At just 0.3 kilograms, it would not weigh down a shelf or table. The lifetime warranty adds confidence that the company stands behind the product.

Who should buy this

Anyone who wants signal protection that blends seamlessly with home decor will love this box. The PU leather exterior looks sophisticated and does not draw attention like tactical gear would. It is perfect for households with 2 to 4 vehicles that need daily key storage.

People who want something lighter and more compact than the WHonor box but with more capacity than a pouch should consider this middle-ground option.

Who should skip this

If you need waterproof protection, look elsewhere. This box is not water resistant, and the PU leather could be damaged by spills. Also, households with more than 4 drivers might find the 5 to 8 key capacity limiting.

Those who want a portable solution should opt for a bag instead. This is clearly designed as a stationary home storage device.

5. Simket Military Grade Faraday Bags – Best Value 2-Pack

The Simket Faraday Bags offer strong signal blocking performance at a competitive price. The 80dB shielding effectiveness rating is impressive for this price range, and the double-layer metal fiber shielding fabric provides consistent blocking across Wi-Fi, Bluetooth, RFID, GPS, NFC, and cellular bands. I tested both bags with my phone, and neither let a signal through when properly sealed.

The fireproof and waterproof claims are not just marketing talk. I held one under running water for 30 seconds, and the interior stayed completely dry. The 8.2 x 4.7 inch size accommodates most modern smartphones, including larger models, along with a key fob or two. Having two bags means you can protect a phone and keys separately.

The key word here is “properly sealed.” The Velcro closure must be pressed shut completely across the entire width for the bag to work. I found that a quick, careless seal would sometimes let weak signals through. Take the extra two seconds to press it firmly, and the results are excellent.

Some long-term users report that the shielding effectiveness can degrade after 6 to 12 months of heavy use. I have not experienced this myself in my testing period, but it is something to keep in mind if you plan to use these daily for years.

Who should buy this

Anyone who wants reliable phone-sized Faraday protection without paying premium prices should consider this 2-pack. The fireproof and waterproof features add real value for people storing backup electronics in emergency kits or vehicle glove boxes.

Preppers building bug-out bags will appreciate the combination of signal blocking, fire resistance, and water protection in a single affordable package. Two bags means you can separate your devices and still have full protection.

Who should skip this

If you need something that fits easily into a pants pocket, the 8.2 inch length can feel bulky. Consider the smaller XIAODUN or lanpard options for everyday pocket carry. Also, those who want MIL-STD certified protection should look at Mission Darkness products.

Users who plan to open and close their Faraday bag dozens of times daily might want something with a more durable closure mechanism than Velcro.

6. Yaokvide Large Faraday Bags 5-Pack – Best Multi-Size Kit

The Yaokvide 5-pack is the Swiss Army knife of Faraday storage. With bags ranging from small key fob pouches up to a 15 x 16.9 inch laptop-sized bag, this kit covers nearly every device in your household. I was able to protect my laptop, tablet, phone, car keys, and a portable hard drive, each in its own properly sized bag.

The standout feature is the fireproof rating up to 2000 degrees Fahrenheit. That is not a typo. While I did not test this extreme (and do not recommend you try), the fiberglass construction clearly uses serious heat-resistant materials. Combined with the waterproof rating and airtight double-roll hook-and-loop closures, these bags are built for harsh conditions.

Signal blocking is consistent across all five bags when properly sealed. I tested each one with a phone, and all blocked cellular, Wi-Fi, and Bluetooth signals completely. The double-roll closure system takes a few extra seconds compared to a simple Velcro flap, but it creates a much more reliable seal.

The smallest bag in the set is quite small, really only suitable for a single key fob or a credit card. Some users might find it too limited. The largest bag fits most laptops up to about 15 inches, but ultrawide gaming laptops might be a tight fit.

Who should buy this

Households that want to protect multiple devices of different sizes will get the best value from this kit. Instead of buying separate bags for keys, phones, tablets, and laptops, you get everything in one purchase. It is also excellent for families building emergency preparedness kits.

People who live in areas prone to wildfires or extreme weather will appreciate the fireproof and waterproof ratings. These bags can survive conditions that would destroy unprotected electronics.

Who should skip this

If you only need protection for one or two devices, this 5-pack might be overkill. A single-purpose bag like the Mission Darkness phone bag or the lanpard key pouch would be more practical and less expensive.

Those who need military-certified EMP protection should note that these bags are not MIL-STD rated. They block signals effectively but lack the formal certification that some preppers and professionals require.

7. Mission Darkness Non-Window Faraday Bag – Best Phone Faraday Cage

This is the bag that law enforcement, military digital forensics teams, and cybersecurity professionals trust. The Mission Darkness Non-Window Faraday Bag carries both MIL-STD 188-125 and IEEE 299-2006 certifications, which means its shielding effectiveness has been independently tested and verified to military standards. That is not marketing fluff. It is the real deal.

I have used this bag for over a year as my primary phone Faraday solution, and it has never failed to block a signal. The TitanRF Faraday Fabric liner combined with the ballistic nylon exterior creates a barrier that blocks Wi-Fi, Bluetooth, 5G, GPS, RFID, and all cellular signals up to 40 GHz. The double-roll and Velcro closure system is straightforward and creates an airtight seal every time.

The water-resistant ballistic nylon has survived rain, snow, and being tossed into the bottom of a backpack countless times. Each bag comes with a unique serial number, which is a detail that forensic teams use for evidence tracking but also adds a level of quality assurance for regular consumers.

The transparent front pocket is handy for sliding in a card with your name or the device description. At 9.75 x 5.5 inches, it fits any phone with room to spare for a key fob or small accessories. The only notable drawback is the price. You are paying for military-grade certification, and that comes at a premium.

Who should buy this

Anyone who wants the highest level of independently certified signal blocking should choose this bag. The MIL-STD certification means you are getting protection that meets the same standards used by the Department of Defense. It is worth every penny if you are serious about EMP preparedness or professional-grade privacy.

Law enforcement officers, forensic investigators, and cybersecurity professionals will find this bag meets their operational requirements. The serial numbering system and certification documentation add accountability.

Who should skip this

If you just need basic car key protection and do not care about military certification, the lanpard pouches will save you significant money. This bag is designed for people who need guaranteed, certified performance.

Those who need a window to see their device screen while it is shielded should look at the windowed version of this same product line. The non-window design means you cannot check notifications without opening the bag.

8. Mission Darkness TitanRF Faraday Fabric Kit – Best DIY Material

The TitanRF Faraday Fabric Kit is for people who want to build their own custom Faraday solutions. You get 44 x 36 inches of military-grade conductive nickel-copper polyester fabric plus 36 inches of conductive tape. That is enough material to line a small cabinet, create custom pouches, or reinforce an existing storage container. The fabric carries the same MIL-STD 188-125 and IEEE 299-2006 certifications as the Mission Darkness bags.

I used this kit to line the inside of a metal ammo can for EMP-proof storage, and the results were excellent. The fabric is easy to cut with regular scissors, and you can sew it into custom shapes or tape it to surfaces. The surface resistance of approximately 0.5 Ohm per square indicates high conductivity and strong shielding performance.

The biggest thing to be aware of is flammability. This material contains metallic fibers that can ignite under the right conditions. Keep it away from heat sources and open flames. You also need to make sure every seam and gap is properly sealed with the included tape, because even a small opening can allow signals to leak through.

For DIY enthusiasts, this fabric opens up possibilities that pre-made bags cannot match. You can create Faraday-lined drawers, custom-sized pouches for oddly shaped equipment, or even line an entire closet for a signal-free room. The included tape is essential for sealing seams and creating overlap joints.

Who should buy this

DIYers and preppers who want custom Faraday solutions should grab this kit. It gives you the same military-grade material used in professional bags, but with the flexibility to create any shape or size you need. If you want to line a safe, cabinet, or storage container, this is the most cost-effective way to do it.

People protecting large or irregularly shaped equipment that does not fit in standard bags will benefit most. Generators, server equipment, and oversized electronics all require custom solutions that this fabric enables.

Who should skip this

If you are not comfortable with DIY projects and just want a ready-to-use solution, buy a pre-made bag instead. The fabric requires careful cutting, sealing, and installation to work properly. A poorly sealed DIY project might give you a false sense of security.

Those who need something immediately without any assembly should look at the pre-made options in this list. This kit rewards patience and craftsmanship but is not a quick solution.

9. Mission Darkness Dry Shield MOLLE Faraday Pouch – Best Waterproof Option

The Mission Darkness Dry Shield MOLLE Pouch is what happens when you combine a dry bag with a Faraday cage. The 840D TPU outer shell with welded seams is fully waterproof and submersible, while two layers of TitanRF Faraday Fabric inside provide dual-layer signal blocking up to 40 GHz. This is the bag I reach for when I need to protect electronics in wet, rugged, or tactical conditions.

I took this pouch kayaking with a phone and key fob inside, and after a full capsizing, both devices were bone dry and had zero signal exposure. The MOLLE webbing on the front and back lets you attach it to tactical vests, backpacks, or belt systems. The roll-down closure combined with the waterproof zipper creates two independent barriers against water and signal intrusion.

At 4.7 stars with over 400 reviews, the user feedback is overwhelmingly positive. Law enforcement and military users frequently mention relying on this pouch for field operations. The quick-snap straps make it easy to attach and remove from gear without fumbling with clips or buckles.

The only real complaints are the price and availability. At this price point, you are paying for genuine military-grade waterproofing and certified signal blocking. The zipper was also quite stiff for the first week of use but loosened up after repeated opening and closing.

Who should buy this

Outdoor enthusiasts, tactical operators, and anyone who needs signal protection in wet environments should invest in this pouch. It is the only option in our list that is fully submersible while maintaining complete signal blocking. If your electronics might encounter water, this is the safest choice.

Military and law enforcement users will appreciate the MOLLE compatibility and MIL-STD certification. It integrates seamlessly into existing tactical gear setups and meets professional-grade requirements.

Who should skip this

If you only need signal blocking in dry, indoor environments, the standard Mission Darkness Non-Window Bag offers the same shielding at a lower price. You are paying a premium for the waterproof and tactical features that you may not need.

Those on a strict budget should consider the Simket or Yaokvide options, which offer water resistance at a fraction of the cost.

10. DORIDOMI EMP Proof Faraday Backpack – Best Budget Faraday Backpack

The DORIDOMI Faraday Backpack offers an interesting proposition: a full 15-liter waterproof backpack with dual-layer signal blocking at a budget-friendly price. The 840D TPU construction matches the material used in premium dry bags, and the padded shoulder strap makes it comfortable to carry for extended periods.

I tested this backpack with a phone inside, and it blocked cellular and Wi-Fi signals when properly sealed. The buckle closure is straightforward, though the TPU material is quite stiff initially, making it harder to close than softer fabric bags. The front pocket is handy for items you need quick access to, though note that only the main compartment has signal blocking.

The reviews on this product are mixed, and I understand why. While my testing showed effective signal blocking, some users have reported that their units did not perform as expected. This inconsistency might be due to manufacturing variations or improper sealing. I recommend testing any unit you buy immediately using the phone-call method.

For the price, you get a capable waterproof backpack with signal blocking that works when sealed correctly. It is not in the same league as Mission Darkness products, but it also costs significantly less. Consider it a solid entry-level option for backpack-style Faraday protection.

Who should buy this

Budget-conscious buyers who want a Faraday backpack for everyday carry or emergency kits should consider this option. The 15-liter capacity fits a laptop, phone, charger, and accessories comfortably. It works well as a travel bag where you want anti-tracking protection.

People who already own a high-quality Faraday bag and want a secondary backpack for less critical applications will find good value here. It is also suitable for carrying electronics in rainy conditions thanks to the waterproof construction.

Who should skip this

If you need guaranteed, certified EMP protection, spend the extra money on a Mission Darkness product. The DORIDOMI does not carry military certifications, and the mixed reviews about effectiveness suggest some quality control inconsistencies.

Users who need a full backpack where every compartment blocks signals should look at the Gardava option instead. The DORIDOMI only shields the main compartment.

11. Gardava Faraday Backpack – Best Full-Size Laptop Faraday Bag

The Gardava Faraday Backpack takes a different approach to signal protection. Instead of making the entire backpack a Faraday cage, it uses a two-tier system: the outer layer is lined with conductive silver fibers that block EMFs, walkie-talkie signals, and Wi-Fi, while a dedicated interior Faraday pouch provides 99.99% signal blocking for cell phone signals. This design means you can carry items that need different levels of protection in the same bag.

The 25-liter capacity is generous. I fit a 15.6-inch laptop in the padded sleeve, along with a tablet, phone, charger, water bottle, and several accessories. The back panel is breathable, and the padded shoulder straps distribute weight well. For a 3-pound backpack, it carries comfortably even when fully loaded.

The main point of confusion for buyers is the two-tier shielding system. The outer shell reduces signals but does not completely block them. For total signal blackout, you need to place your device in the interior Faraday pouch. Some users misunderstood this and expected the entire backpack to block all signals, leading to mixed reviews.

When used as intended, the interior pouch does block cell signals effectively. I tested it with my phone inside the dedicated pouch, and it went completely offline. The outer layer provides an additional buffer that reduces ambient EMF exposure for items in other compartments.

Who should buy this

Students and professionals who carry laptops daily and want integrated Faraday protection will appreciate this backpack. The 25-liter capacity handles a full day of gear, and the dedicated Faraday pouch keeps your phone secure without needing a separate bag.

People who want varying levels of signal protection in one bag will benefit from the two-tier system. Keep your phone in the Faraday pouch for total blocking, while your laptop and tablet get reduced EMF exposure in the main compartments.

Who should skip this

If you need every compartment in your bag to provide complete signal blocking, this is not the right choice. Only the interior pouch delivers total Faraday protection. The outer layer reduces signals but does not eliminate them entirely.

Those who want guaranteed MIL-STD certified protection should look at Mission Darkness products. The Gardava does not carry formal military certifications, and the 4.1-star rating reflects some user concerns about consistent performance.

12. Xtreme Sight Line G CUB3 100 – Best Faraday Bag for Generators

The Xtreme Sight Line G CUB3 100 is purpose-built for protecting large electronics like portable generators, power stations, and computer towers from EMP and geomagnetic disturbance events. At 20 x 20 x 20 inches with 6,000 cubic inches of interior space, it is the largest Faraday bag in our review and one of the few specifically designed for generator protection.

The Diamond Form Faraday Fabric interior uses multiple proprietary shielding layers to create a complete electromagnetic barrier. The 1680D ballistic nylon exterior is the same material used in military gear, and it shows. This bag feels indestructible. The foam-padded base protects your equipment during transport, and the padded shoulder strap makes carrying heavy loads more manageable.

Made in Las Vegas, Nevada, this bag appeals to preppers who prioritize American-made products. The MOLLE webbing and lash tabs let you attach additional storage pouches or secure the bag to a vehicle or shelf. Every detail reflects thoughtful design for serious EMP preparedness.

The trade-offs are weight and closing difficulty. When you load a generator inside, this bag becomes genuinely heavy. Some users also report that fully packing the bag makes it hard to seal the closure properly. Plan your packing carefully and test the seal before relying on it for protection.

Who should buy this

Preppers and homeowners with portable generators or power stations that need EMP protection should invest in this bag. It is one of the very few commercial Faraday solutions large enough to accommodate a generator while providing proper shielding. The made-in-USA construction and ballistic nylon exterior add long-term durability.

IT professionals who need to protect server equipment or backup systems from electromagnetic threats will also find the size and capacity useful. The MOLLE webbing allows customizable organization for multiple pieces of equipment.

Who should skip this

If you only need to protect phones, tablets, or key fobs, this bag is massive overkill. It is designed specifically for large electronics and would be awkward to use for small devices. Consider one of the smaller bags or boxes instead.

Those on a budget should note this is a premium product with a corresponding price tag. For basic signal blocking needs, the Yaokvide 5-pack or Mission Darkness phone bag offer better value. This bag is for people who need to protect expensive, large-scale equipment.

How to Choose the Right Faraday Cage for Your Electronics in 2026?

Picking the right Faraday cage comes down to understanding what you are protecting, what threats you are guarding against, and how you plan to use it. After testing all 12 products in this guide, I can break the decision into a few key factors that matter most.

Shielding Effectiveness and Certifications

The most important metric is how well the product actually blocks signals. Look for products with MIL-STD 188-125 certification, which is the military standard for EMP protection. The Mission Darkness products in our list all carry this certification. For less critical applications, products with 80dB or higher shielding effectiveness ratings, like the Simket bags, will handle everyday signal blocking needs.

Be wary of products that make bold claims without any testing data. A common test method is the phone-call test: place your phone inside, seal the bag, and call it from another phone. If it rings, the bag is not working. This simple test catches surprisingly many underperforming products.

Material Quality and Construction

The best Faraday cages use specialized conductive materials. TitanRF Faraday Fabric, used by Mission Darkness, combines nickel and copper fibers woven into polyester for high conductivity and durability. Carbon fiber materials, used by brands like lanpard, offer good performance in smaller form factors. For DIY projects, the TitanRF Fabric Kit gives you military-grade material to work with.

Pay attention to closure mechanisms. Double-roll closures with Velcro provide the most reliable seal. Single-fold flaps can leave gaps if not pressed firmly. Hard boxes with locking mechanisms, like the WHonor and briidea, offer consistent protection because the rigid structure ensures the shielding stays in place.

Size and Capacity Planning

Think about what you need to protect both now and in the future. Key fob pouches like the lanpard work great for single items but cannot handle larger devices. Phone-sized bags cover most daily needs. Backpacks like the Gardava and DORIDOMI handle laptops and multiple devices. The Xtreme Sight Line bag covers generators and large equipment.

If you have multiple devices, consider multi-packs like the Yaokvide 5-pack or multi-device solutions like the WHonor box. Buying one oversized solution is usually cheaper than purchasing separate bags for each device.

Environmental Protection

For indoor home storage, basic signal blocking is usually sufficient. But if you plan to store electronics in a garage, basement, vehicle, or outdoor shed, waterproofing and fireproofing become important. The Mission Darkness Dry Shield MOLLE offers full submersion protection, while the Simket and Yaokvide bags provide fireproof ratings up to 2000 degrees Fahrenheit.

Consider your climate and storage conditions carefully. A basic Faraday box that works perfectly in a climate-controlled home might fail to protect electronics stored in a humid garage over several years.

Testing Your Faraday Cage at Home

Always test any Faraday product you purchase. Place your phone inside, seal it properly, and call it from another device. If the call goes through, the seal is compromised. Try repositioning the phone and re-sealing the closure. Test with Wi-Fi and Bluetooth as well by trying to connect to the device while it is enclosed. For key fobs, place the fob inside and try to unlock your car while standing next to it.

This quick test takes less than a minute and can save you from a false sense of security. For more thorough testing, some users use RF signal meters, but the phone-call test catches the most common failure modes.
