What Is Rekeying?
Rekeying is the process of changing the internal mechanism of a lock so that it works with a new key while keeping the same lock hardware. Instead of replacing the entire lock, a locksmith adjusts the lock’s pins or tumblers to match a new key, rendering the old key useless.
This process is commonly performed when security needs to be updated without the hassle and cost of full lock replacement.
How Does Rekeying Work?
A locksmith follows these steps to rekey a lock:
- Remove the Lock Cylinder – The locksmith takes out the lock cylinder, which contains the pins and springs inside the lock.
- Replace the Pins – The existing pins are removed and replaced with a new set that corresponds to a different key pattern.
- Reassemble the Lock – The lock is put back together, and the new key is tested to ensure it works smoothly.
- Old Key Becomes Useless – Since the pin configuration has changed, the old key will no longer work in the rekeyed lock.
When Should You Rekey Your Locks?

You should consider rekeying your locks in the following situations:
- Moving into a new home or office – You don’t know who else has copies of the old key.
- Lost or stolen keys – Prevent unauthorized access by ensuring old keys no longer work.
- Tenant or employee change – If a tenant or employee leaves, rekeying ensures previous keys won’t work.
- Divorce or separation – Rekeying adds security by restricting access to certain individuals.
- Upgrading security – Rekeying multiple locks to work with a single key (keyed alike) enhances convenience.

✅ Quick and Simple: Takes only a few minutes per lock.
✅ Improves Security: Eliminates access from lost or old keys.
