Cost to Rekey Locks
Rekeying a lock changes the internal pins in its cylinder so they match a new key. It is a moderate task that involves removing the doorknob and cylinder, removing the old pins and springs, then inserting new pins to the new key’s bitting code before reassembling the lock.
Common reasons homeowners do this job
- Changing an existing lock to work with new keys.
- Updating locks as part of a home upgrade.
- Keeping a lock that is in good working condition while changing its keying.
- Assessing a worn or damaged lock to determine whether it is still suitable for rekeying.
DIY or call a pro?
Rekeying is a legitimate DIY project when the lock is in good working condition and the correct kit is available. A professional is worth considering if removing the cylinder, handling the small pins and springs, or matching pins to the new key’s bitting code feels uncomfortable. Keep the workspace clean and organized, and ease the plug out gently with the follower tool so the pins stay in place.
Frequently asked questions
- Can I rekey my own locks or is it better to hire someone?
- A homeowner can rekey a working lock with a compatible rekeying kit, new keys, and careful handling of the cylinder parts. The rekeying work takes 20 minutes per lock. Consider professional help if the pin sequence, plug removal, or reassembly is outside your comfort level.
- What makes the price of rekeying locks go up?
- The price scales with the job size and number of locks, labor time, and materials. A small job may also include a minimum or trip charge.
- What should I check before buying a rekeying kit?
- Identify the lock’s brand and model first, then verify that the lock is in good working condition. The kit needs pins and keys that are compatible with that lock.
- Why is it important to ease the cylinder plug out gently?
- Forcing the plug can spill the small pins. Work on a clean, organized surface so the pins and springs can be kept together and reinstalled correctly.
