Rekeying a home lock sounds like something only a professional should do, right? Not necessarily. If you’ve ever worried about who might have a copy of your house key—or just want a fresh start without replacing your entire lock—then rekeying could be your perfect DIY solution.
Let’s dive into 10 simple steps to rekey a home lock, how to do it safely, and when you might need to call in a pro.
Why You Might Need to Rekey Your Home Lock
Rekeying is more than just a cool trick—it’s a practical move for better residential security.
Lost Your Keys? Here’s Why Rekeying Matters
If your keys are lost, anyone who finds them potentially has access to your home. Rekeying changes the internal pins of the lock so old keys no longer work—essentially giving you peace of mind without swapping out the entire lock. Read more about regaining access after a lockout here.
Moving Into a New Home
You don’t know how many copies of the key the previous owners made. Rekeying guarantees you’re the only one with working keys. It’s a must for residential security and should be part of every new homeowner checklist. Visit home locks and residential security for more protection tips.

Step-by-Step Guide: How to Rekey a Home Lock
Let’s get hands-on! Here’s how to rekey your home lock in 10 detailed steps.
Step 1: Remove the Lock from the Door
Use a screwdriver to detach the lock from the door. Be gentle—don’t strip the screws.
Step 2: Take Apart the Lock Cylinder
Remove the plug from the cylinder using your cylinder removal tool. This gives you access to the internal pins.
Step 3: Remove the Old Pins
Dump the old pins out—they’re designed to match your old key and won’t work with your new one.
Step 4: Match New Pins with Your New Key
Use the key gauge from your rekeying kit to determine pin sizes. Each groove on your new key corresponds with a specific pin height.
Step 5: Insert the New Pins
Drop the new pins into the cylinder chambers. Make sure they align perfectly when the new key is inserted.
Step 6: Reassemble the Lock Cylinder
Use your follower tool to slide the plug back in without mixing up your pin configuration.
Step 7: Reinstall the Lock in the Door
Screw everything back into place. Don’t overtighten—you could warp the lock housing.
Step 8: Test the New Key
Before you walk away feeling victorious, test your new key multiple times. Smooth turn? You nailed it!
Step 9: Make Extra Copies of the New Key
Once you confirm the new key works, make 2-3 extra copies. No more lockouts!
Step 10: Secure and Maintain Your Rekeyed Locks
Spray graphite or silicone lubricant into the keyhole every few months to prevent wear. Regular checkups are part of good lock maintenance.
Rekeying vs. Replacing: What’s Better?
Sometimes, you wonder—is it even worth the hassle of rekeying?
Cost Comparison
Rekeying is generally more affordable than replacing locks entirely. A full replacement can run $50 to $200+ per lock, while a rekey kit costs around $10–$30.
Security Benefits
If your current lock is worn out or outdated, replacing it with a more modern, high-security model might be the better call. Browse the best door locks for smart, secure upgrades.
