Rekey or Replace a Door Lock? Boston Homeowner Guide
After moving, losing keys or noticing a worn lock, homeowners often wonder whether to rekey the existing cylinder or replace the hardware. The best option depends on both security and mechanical condition.
When rekeying makes sense
Rekeying changes the internal keying of a compatible cylinder so the previous operating keys no longer work. It may be suitable when the hardware is in good shape but you want to control who has working keys. It does not fix a damaged latch, a sagging door or a faulty lock body.
When replacement or repair is more appropriate
- The lock or latch binds even when the door is open
- The cylinder is heavily worn, corroded or damaged
- You want to upgrade to a different lock grade or smart lock
- The existing hardware is incompatible with your security goals
- The strike plate or alignment needs attention
Frequently asked questions
Rekeying changes which key works; it does not improve the mechanical strength of the lock.
Sometimes, if their cylinders and keyways are compatible. A locksmith can check the hardware before recommending a keyed-alike setup.
