How Lock Rekeying Works

Short answer: Rekeying is one of the most useful and affordable locksmith services. Here's what it actually involves and when to choose it.

Rekeying is one of the most useful and affordable locksmith services. Here's what it actually involves and when to choose it.

Changing the pins, not the lock

Inside a pin-tumbler lock, small pins must line up at the shear line for the key to turn. Rekeying replaces those pins so a new key aligns them and old keys no longer do, all without swapping the lock body. This is why rekeying is quicker and cheaper than replacement.

Keying alike

When rekeying several locks, a locksmith can set them to the same key so one key opens every door. This adds convenience without weakening security, since old keys are still invalidated. It is popular for homes with multiple entry points.

When rekeying isn't enough

Rekeying resets access but does not upgrade a lock's strength or fix worn hardware. If your locks are damaged, outdated, or you want higher-grade protection, replacement is the better choice. A locksmith can tell you which option fits your situation.
