What does rekeying a residential lock involve?

Rekeying involves changing the internal mechanism of your lock so that existing keys will no longer work and a new key is required. This is done without replacing the whole lock hardware.

When should I consider a full lock replacement instead of rekeying?

A full lock replacement is suggested if the lock is damaged, outdated, non‑compliant with current security standards or if you want to upgrade to a more advanced lock system. If the hardware is in good condition and compatible, rekeying may be sufficient.

Can you rekey all types of home door locks?

Yes; we can rekey most standard residential locks including deadbolts, knob locks and lever handle locks. We will inspect the existing hardware and confirm compatibility before proceeding.

What is the benefit of rekeying when I just moved into a new home?

Rekeying ensures that previous owners, tenants or anyone who may have had a key can no longer access your home. It provides more control over who holds the new keys and enhances your home security without changing all the lock hardware.

Will rekeying affect my existing keys for other doors in the house?

If you have multiple doors keyed alike (same key for several locks), we can rekey all of them to use a single new key or separate keys depending on your preference. We will discuss your keying options before the work begins.
