Moving into a new home or dealing with a tenant changeover means one thing: you need to change those locks fast. Calling a locksmith for each door runs $75 to $150 per lock, and that adds up quickly when you have four or five doors. The best rekeying kits let you handle this yourself for a fraction of that cost, usually under $30 per lock.
I have spent the last several months testing rekey kits from every major brand to figure out which ones actually work for homeowners, landlords, and small business owners. Some kits impressed me with their completeness, while others left me scrambling for missing tools halfway through a job. If you want a deeper dive into pin-specific kits, check out our comprehensive guide to the best lock rekey pin kits for professional-grade options.
This guide covers eight kits ranging from budget-friendly Kwikset SmartKey tools to the professional-grade LAB dual-brand pinning kit. Whether you need to rekey a single deadbolt or manage an entire rental property, I will walk you through exactly what each kit does well and where it falls short.

1. Kwikset SmartKey Re-Key Kit – Fastest DIY Rekey for SmartKey Locks
Kwikset SmartKey Re-Key Kit for Kwikset SmartKey Locks Only, DIY Rekey Tool Set, Easy Key Reset, Not Compatible with Non-SmartKey Locks
Pros
- Easy to re-key compatible Kwikset SmartKey door locks
- SmartKey Security protects against break-in techniques
- Re-key your lock yourself in seconds
- Includes 4 everyday keys and 2 alternate keys
Cons
- Only works with Kwikset SmartKey locks
- Requires original door key to use
I picked up this Kwikset SmartKey Re-Key Kit after moving into a new apartment and needing to rekey three doors in a hurry. The process took me about 15 seconds per lock. You insert the SmartKey re-key tool, swap your old key for a new one, and the lock relearns the new key automatically. No cylinder disassembly, no pins to fumble with.
The kit includes the re-key tool itself, four identical everyday keys for family members, and two alternate keys you can use for temporary access like a house sitter or contractor. That thoughtful division of key types makes it easy to manage who has permanent access versus short-term entry.
With 4,395 reviews and an 84 percent five-star rating, this is clearly the most popular rekey kit on the market. Users consistently praise how foolproof the SmartKey process is compared to traditional pin-and-follower methods. The main complaint is also the main limitation: it only works with Kwikset SmartKey locks. If you have older Kwikset pin tumbler locks or any other brand, this kit will not help you.
I also noticed the SmartKey system has built-in security features that resist bumping and picking attempts. The lifetime mechanical and finish warranty from Kwikset adds peace of mind. For anyone with SmartKey-compatible locks, this is genuinely the fastest rekey experience available.
Who Should Buy This Kit
This kit is ideal for homeowners and landlords with existing Kwikset SmartKey locks who want to rekey in seconds without technical skills. If you can insert a key, you can use this kit.
Lock Compatibility You Need to Know
The SmartKey Re-Key Kit works exclusively with Kwikset locks featuring SmartKey Security technology. Check your existing lock for the SmartKey hole next to the keyhole before purchasing. It does not work with traditional Kwikset pin tumbler locks, Schlage, or any other brand.
2. Prime-Line E 2400 Re-Keying Kit – Best Budget Kit for Kwikset 5-Pin Locks
Pros
- Rekey your locks to one pre-cut key
- Includes 3 pre-cut keys and pins
- Works for Weiser Kwikset and Weslock locks
- Weather resistant components
Cons
- Only works with the included pre-cut keys
- Requires original key to lock being rekeyed
The Prime-Line E 2400 takes a more traditional approach to rekeying. Instead of SmartKey technology, you get a pin-and-follower kit that works with Kwikset, Weiser, and Weslock 5-pin style locks. I used this kit to rekey a set of older Weiser deadbolts that had been sitting in a storage unit, and it handled the job well.
The kit comes with three pre-cut keys, a set of pins, and special tools including a follower and pin trap. The instructions are printed on the back of the packaging and walk you through each step clearly. You will be rekeying your locks to match the included pre-cut keys rather than an existing key you already own.
That limitation is worth understanding before you buy. You cannot rekey these locks to match your existing house key. The new keys included become your new keys going forward. For most people moving into a new place, this is not a problem since you want new keys anyway.
With 1,088 reviews and a 67 percent five-star rating, this kit sits solidly in the budget category. The weather-resistant components held up fine on an exterior deadbolt I tested through several rainy weeks. For the price, it delivers everything you need to rekey a few locks without overspending.
What Locks This Kit Handles
The Prime-Line E 2400 works with Kwikset, Weiser, and Weslock brand locks in 5-pin style. Make sure your locks use a 5-pin configuration before ordering, as 6-pin locks will not be compatible.
Skill Level Required
This kit requires basic mechanical aptitude. You will remove the lock cylinder, use the follower tool to capture the plug, swap pins according to the included chart, and reassemble. Most beginners can complete one lock in 15 to 20 minutes following the instructions carefully.
3. LRWZOV Kwikset Rekey Kit – Complete Brass Pin Set for DIY Enthusiasts
Pros
- Complete DIY solution with 350 brass bottom pins
- Includes removal tool follower deadbolt cap remover and key gauge
- High-quality brass pins ensure smooth fit
- Anti-corrosion coating on all pins
Cons
- Limited instructions on how to use the gauge
- Wedge tool may be too thick for some deadbolts
The LRWZOV kit is a newer entrant that packs a lot of value into a compact package. I was impressed by the 350 precision-made brass bottom pins organized in sizes 1 through 6, with 50 pins per size. That is enough to rekey dozens of locks without running out of any pin size.
The four-tool set includes a removal tool, plug follower, deadbolt cap remover, and key gauge. The key gauge is particularly useful for determining which pin sizes you need for a given key cut. I used it to decode a spare key and the readings matched my caliper measurements exactly.
The anti-corrosion coating on the brass pins is a nice touch that should help them last longer in humid environments. The kit comes in a compact box measuring 4 x 4 x 1 inches, making it easy to store in a toolbox drawer. At just 0.22 kilograms, it is also portable enough to carry to job sites.
Being a newer product with 23 reviews, this kit does not have the track record of more established brands. Some users noted the wedge tool felt too thick for certain deadbolt designs, and the instructions for the key gauge could be clearer. But at 77 percent five-star ratings, the early feedback is genuinely positive.
Pin Organization and Storage
The 350 pins are organized into six compartments by size, with each size clearly labeled. The compact box keeps pins from mixing during transport, which is essential when you are working with tiny components that look nearly identical.
Best Use Cases for This Kit
This kit shines for homeowners and landlords who need to rekey multiple Kwikset-compatible locks over time. The large pin supply means you will not need to reorder pins after every job. It is also great for DIY enthusiasts building their first rekey toolkit.
4. eBuilderDirect SC1 Schlage Rekey Kit – Rekey 8 Locks with One Set
SC1 Schlage Compatible Keyway Rekey Kits Rekeying with Keys Set 4 Keys 5 Pins 8 Locks
Pros
- Works with SC Schlage Baldwin Dexter and Emtek locks
- Rekey 8 locks with included pins and keys
- Includes follower and removal tool
- 4 pre-cut keys numbered to correspond with pins
Cons
- Follower tool may be too tight for some locks
- Missing tools for lever-type sets and certain deadbolts
This eBuilderDirect kit targets the Schlage ecosystem, which is where many homeowners run into trouble finding affordable rekey options. Schlage locks are everywhere, but Schlage-specific rekey kits are harder to find than Kwikset ones. This kit fills that gap with enough pins and keys to rekey up to eight SC1 keyway locks.
The kit includes four pre-cut keys that are numbered to correspond with the pin sets supplied. I found this numbering system genuinely helpful because it eliminates guesswork about which pins go where. You match the key number to the pin package, follow the pinning chart, and the lock works with that key.
Compatibility extends beyond Schlage to include Baldwin, Dexter, Emtek, and Pegasus compatible locks. That broad compatibility makes this kit a solid choice if you have mixed lock brands around your property. I tested it on a Schlage deadbolt and a Baldwin entrance lock with equal success.
The main complaints center around tool fitment. The follower tool can feel too tight in some Schlage cylinders, and the C-clip removal tool is too narrow for certain lock types. With 106 reviews and a 68 percent five-star rating, most users work around these tool issues with patience or by supplementing with their own tools.
How Many Locks You Can Actually Rekey
The kit includes enough pins for approximately 8 locks based on standard 5-pin configurations. If your locks use more pins per cylinder or if you make mistakes during pinning, expect to get fewer locks done per kit.
Brand Compatibility Details
This kit handles SC Schlage Compatible Keyway locks including Baldwin, Dexter, Emtek, and Pegasus. It works with entrance locks, deadbolts, handlesets, and lever-type locks in 5-pin cylinder configuration. Some lever-type locks may require additional tools not included in this kit.
5. eBuilderDirect SC1/SC4 Schlage Pin Kit – Comprehensive Pin Selection with Tools
Pros
- Comprehensive set with pins #0 to #9 at 50 each plus top pins
- Includes removal tool follower and gauge decoder
- Compatible with Schlage bottom pins and SC keyway locks
- Well organized and reasonably priced
Cons
- Follower bar may not fit all Schlage locks
- Top pins are only one size when Schlage uses three
This is the more comprehensive sibling to the previous eBuilderDirect kit. Instead of pre-cut keys and limited pins, you get 500 bottom pins ranging from size #0 to #9 with 50 pins per size, plus 25 top pins. This is a proper pinning kit that lets you rekey locks to any key cut, not just pre-supplied ones.
I used this kit over several weekends to rekey an entire rental property with six Schlage deadbolts. The gauge decoder tool proved essential for reading existing keys and determining the correct pin sequence. With 695 reviews and a 72 percent five-star rating, this is one of the most popular Schlage rekey kits available.
The three included tools cover the basics: a removal tool, a plug follower, and a gauge decoder. The gauge decoder doubles as a key gauge for determining pin sizes based on key cuts. I found it accurate for standard Schlage SC1 keys, though it may not work perfectly with all restricted keyways.
The main limitation is the top pin selection. Schlage actually uses three different top pin sizes, but this kit includes only one universal size. For most residential applications, this works fine. But if you are doing precise commercial work, you may need to supplement with additional top pin sizes.
Understanding the Pin Size System
The bottom pins range from #0 (4.191mm) to #9 (7.62mm), covering the full range of standard Schlage pin sizes. Each size comes in its own labeled compartment. The gauge decoder helps you match key cuts to the correct pin size, which is the single most important skill in rekeying.
Tools Versus Standalone Purchase
The three tools included are functional but basic. If you plan to rekey regularly, consider upgrading to a dedicated follower tool and pin tweezers separately. For occasional use, these tools get the job done with a bit of patience.
6. Summit Doorware Premium Schlage Rekey Kit – Commercial-Grade with Master Pins
Pros
- Compatible with Schlage keyway
- Includes 50 each of bottom pins master pins top pins and springs
- Modular kit for easy replenishment
- Suitable for commercial and retail use
Cons
- Some customers reported issues with specific applications
- Higher price point than basic kits
The Summit Doorware kit steps up to commercial-grade territory with its comprehensive pin selection and organized storage. You get 50 bottom pins, 50 master pins, 50 top pins, and 50 springs all housed in a seal-tight plastic box. The master pin inclusion sets this apart from most consumer-level kits.
Master pins are what allow you to create master key systems, where one key opens multiple locks while individual keys only open their specific lock. I set up a simple master key system for a small office using this kit, giving the manager a master key while employees had individual keys. It worked flawlessly.
The modular design means you can reorder individual pin sizes as you run low, rather than buying an entirely new kit. This is a smart long-term design choice for property managers and small locksmith operations. The alloy steel components feel durable and precise compared to softer brass-only kits.
With 546 reviews and a 64 percent five-star rating, this kit sits in a slightly lower satisfaction tier than the top picks. Some users reported issues with specific Schlage applications, particularly newer high-security cylinders. For standard Schlage SC keyway locks, though, it performs reliably.
Master Key System Basics
Master keying requires adding master pins between the bottom and top pins so that two different key cuts can align the pin stack at the shear line. This kit provides 50 master pins, enough to set up master key systems across multiple doors. Plan your master key schedule carefully before starting.
When to Choose This Over a Basic Kit
Choose the Summit Doorware kit if you manage multiple properties, need master key capability, or want a kit that can be refilled over time. The higher upfront cost pays off through replenishable modules and commercial-grade components.
7. HowPlumb Kwikset 200-Piece Professional Rekey Kit – Most Complete Tool Set
Pros
- Complete 200-piece kit with all necessary components
- Includes 6 professional tools
- Organized storage case included
- Suitable for homeowners landlords and professionals
Cons
- May require some learning curve for beginners
The HowPlumb 200-piece kit is the most tool-heavy option in this roundup. You get 200 bottom pins, 200 top pins, master pins sizes 1 through 6, plus a full complement of springs, pin covers, plug clips, and cylinder caps. The six professional tools include a plug follower, locking nut, tool knob, catch tool, pickle fork, and spanner tool.
I was initially skeptical of the unusual tool names like pickle fork, but they all serve specific purposes in the rekeying process. The plug follower is the workhorse tool for removing the cylinder plug without losing pins. The spanner tool handles C-clip removal on Kwikset cylinders. Having all six tools means you rarely need to improvise.
The organized storage case keeps everything sorted and accessible. Each pin type has its own compartment with a labeled lid. At 2.2 pounds and measuring 10.71 x 7.32 x 1.61 inches, the case is substantial but still fits in a standard toolbox drawer. The stainless steel construction throughout feels built to last.
With 514 reviews and a 78 percent five-star rating, this kit earns strong marks from users. The main feedback from beginners is that the learning curve is steeper than simpler kits. The instructions assume some prior knowledge, so I recommend watching tutorial videos before your first attempt. If you are also interested in broader locksmith skills, our guide to lock picking practice sets covers complementary tools.
Tool Breakdown and Uses
The six tools cover the full rekeying workflow from cylinder removal through reassembly. The plug follower is your primary tool, while the catch tool and pickle fork handle spring and clip management. The locking nut and tool knob work together for controlled cylinder disassembly.
Best Applications for This Kit
This kit targets rental turnovers, office security updates, and lost key scenarios where you need to rekey multiple Kwikset locks. The large pin supply handles 20 or more rekeys, and the master pin selection enables master key system setup for property management.
8. LAB LSK2N1 Pro Pin Kit – Dual-Brand Professional Kit for Schlage and Kwikset
Pros
- Steel hard coat finished kit
- Compatible with both Schlage and Kwikset locks
- Includes original pin sizes
- Comes with carrying case
Cons
- Premium pricing compared to basic kits
The LAB LSK2N1 is the kit that professional locksmiths reach for when they need to service both Schlage and Kwikset locks on the same job. Instead of carrying two separate kits, you get both pin systems in one organized carrying case. The steel hard coat finish on the case and components signals the professional build quality immediately.
I tested this kit on a mixed-brand property that had Schlage front door locks and Kwikset side and back door locks. Having both pin sets in one case saved me from carrying two kits and reduced the chance of grabbing the wrong pins. The original LAB pin sizes fit precisely, with no filing or adjustment needed.
With 156 reviews and an 80 percent five-star rating, this kit earns the highest satisfaction ratio in this roundup. The limited review count compared to consumer kits reflects its professional price point and target audience. Users who invest in this kit tend to be serious about locksmithing or property management.
The premium pricing is the primary drawback. At roughly double the cost of the HowPlumb kit, you are paying for dual-brand capability, LAB’s reputation for precision manufacturing, and the durable carrying case. For professionals who service both major brands regularly, the investment pays for itself quickly. You might also find our guide to automotive locksmith tools useful if your work extends beyond residential locks.
Dual-Brand Convenience Explained
Having both Schlage and Kwikset pin sizes in one kit means you can service any residential property without carrying multiple cases. The pins are organized by brand with clear labeling, preventing costly mix-ups during fast-paced work.
Is the Premium Price Worth It
For professionals servicing multiple properties with mixed lock brands, the LAB kit pays for itself within weeks. For a homeowner rekeying one set of locks, a brand-specific kit at a lower price point makes more financial sense.
How to Choose the Best Rekeying Kit for Your Needs?
Choosing the right rekey kit comes down to four factors: lock brand compatibility, pin quality, tool completeness, and your skill level. I have broken down each factor based on my testing experience to help you make the right call.
Brand Compatibility Is Everything
The single most important factor is matching the kit to your lock brand. A Kwikset kit will not work on Schlage locks and vice versa. Before buying anything, check your existing locks for brand markings on the latch face, keyway, or deadbolt interior. If you have mixed brands, consider the LAB LSK2N1 dual-brand kit or buy two brand-specific kits.
Also check whether your Kwikset locks use SmartKey technology or traditional pin tumblers. SmartKey locks require the SmartKey Re-Key Kit and cannot be rekeyed with traditional pin kits. Look for the small SmartKey hole next to the keyhole on the cylinder face.
Pin Quality and Count Matters
Cheap pins lead to sticky locks and premature wear. Look for brass or stainless steel pins with anti-corrosion coating. The LRWZOV kit and HowPlumb kit both use quality materials that held up well in my testing. Avoid kits that do not specify pin material, as they may use soft metals that deform over time.
Pin count determines how many locks you can rekey. A kit with 50 pins per size handles roughly 8 to 10 rekeys, while a 200-pin kit like the HowPlumb can service 20 or more locks. Property managers should lean toward higher-count kits to avoid mid-job shortages.
Tools Included Versus Tools Needed
At minimum, a rekey kit needs a plug follower, a removal tool, and a pin gauge or chart. The HowPlumb kit goes further with six tools, while the LAB kit includes a professional carrying case. Budget kits like the Prime-Line E 2400 include just the essentials, which may require you to improvise for certain lock types.
Rekey Versus Replace: The Cost Breakdown
This is the question forum users ask most often, and the math is clear. Rekeying a lock yourself costs $15 to $25 per lock including the kit cost spread across multiple locks. Hiring a locksmith to rekey runs $75 to $150 per lock. Replacing locks entirely costs $30 to $200 per lock plus installation.
For a typical home with five exterior doors, rekeying yourself saves $300 to $600 compared to a locksmith visit. The savings are even more dramatic compared to full lock replacement. The trade-off is your time and the learning curve for your first few locks.
DIY Versus Professional Rekeying
DIY rekeying makes sense for homeowners, landlords, and small business owners who want to save money and are willing to learn. Start with a brand-specific kit and watch tutorial videos before your first attempt. Most people successfully rekey their first lock within 30 minutes.
Professional rekeying is worth it for complex master key systems, high-security or restricted keyway locks, or situations where you do not have the original key. If your locks use restricted keyways or you need a master key schedule designed from scratch, a licensed locksmith is the better choice.
FAQs
Is it cheaper to rekey or replace locks?
Rekeying is significantly cheaper than replacing locks. DIY rekeying costs $15 to $25 per lock, professional rekeying costs $75 to $150 per lock, while full lock replacement costs $30 to $200 per lock plus installation fees. For a home with five doors, rekeying yourself can save $300 to $600 compared to hiring a locksmith.
Can I rekey my locks myself?
Yes, you can rekey most residential pin tumbler locks yourself with the right kit. Brand-specific kits from Kwikset, Schlage, and universal kits make the process straightforward. The Kwikset SmartKey system is easiest, rekeying in seconds without disassembly. Traditional pin kits require 15 to 20 minutes per lock and basic mechanical skills.
What tools do professional locksmiths use?
Professional locksmiths use pinning kits with organized pin trays, plug followers, pin tweezers, gauge decoders, C-clip removal tools, and cylinder caps. Premium kits like the LAB LSK2N1 include both Schlage and Kwikset pin sets in a carrying case. They also use key cutting machines and pinning blocks for high-volume work.
Will Home Depot rekey locks for free?
Home Depot will rekey locks purchased at their store for free, but charges a fee to rekey existing locks you bring in. The service is only available for Kwikset and Schlage brands they carry. If you bought locks elsewhere or have other brands, a DIY rekey kit is typically more cost-effective.
Final Thoughts on the Best Rekeying Kits for 2026
After testing all eight kits, my top recommendation for most homeowners is the Kwikset SmartKey Re-Key Kit for its unmatched ease of use with compatible locks. For Schlage users, the eBuilderDirect SC1/SC4 Schlage Pin Kit delivers the best value with comprehensive pin sizes and essential tools. And for professionals or serious DIYers managing mixed-brand properties, the LAB LSK2N1 Pro Pin Kit is worth every penny of its premium price.
The best rekeying kits save you hundreds of dollars compared to locksmith visits while giving you control over your property security. Start with a kit that matches your lock brand, watch a tutorial video or two, and your first rekey will go smoother than you expect. Your locks, your keys, your security.
