Short answer
Rekey when the lock works well and you only need to change who has access. Replace when the lock is damaged, worn, the wrong type, or you want different features.
What rekeying actually changes
Inside a pin-tumbler cylinder, small pins line up only with the correct key. Rekeying swaps those pins so a new key works and old keys stop working. The handle, deadbolt and finish stay the same.
Because the hardware stays put, rekeying is often a less disruptive way to retire unknown copies of keys.
When replacement is the better answer
Rekeying cannot fix a bent bolt, a cracked housing or a mechanism that is worn out. It also will not add new functions such as a keypad.
- Visible damage after a break-in attempt
- A lock that sticks even with the door open
- You want a smart lock or a different style
- The lock brand is incompatible with your other keys
Keying several doors alike
Locks that share a keyway can usually be rekeyed to one key. Different brands may need a compatible cylinder or new hardware. Photos of the lock faces and your key help answer this quickly.
When to call instead of reading
- You moved in and do not know who has keys
- A key was lost with your address
- A lock is damaged or will not turn
