Rekeying Costs and Factors
Rekeying refers to changing the internal tumblers so the lock works with new keys, without replacing the lock. It realigns the pins to work with a new set of keys, providing the same protection as replacing the lock, for less cost.
Factors affecting the cost to rekey locks include:
- Complexity of the lock
- Number of locks
- Variation in lock types
- Rekeying process
For most locks, having a professional locksmith rekey on-site costs $40-$60 per lock. Additional costs come from:
- New key cuts
- Car key replacements
- Travel fees
Rekeying your own locks is cheaper but requires tools, skills and carries risks. Kits are available from hardware stores for DIY rekeying.
Rekeying vs. Lock Replacement
Rekeying is much cheaper than replacing locks, as it involves only changing the lock’s internal mechanism, not the entire lock itself.
If you are unsure about whether to rekey or replace your locks, it is best to consult with a professional locksmith. They can assess the condition of your locks and provide expert advice on the best course of action.
