The pin stack is what changes
A pin tumbler cylinder holds a stack of pins that only line up for a specific key cut. Rekeying swaps those pins so the shear line matches your new key instead. Because the housing, bolt and finish stay the same, a lock rekeying Toronto visit is faster and cheaper than a full replacement, and the door keeps hardware that already fits properly.
- Same cylinder, new pin stack
- Cheaper than new hardware
- Bolt throw retested afterwards
