Short answer: After moving into a new home or losing a key, you have two ways to restore security: rekeying or replacing the locks entirely.

After moving into a new home or losing a key, you have two ways to restore security: rekeying or replacing the locks entirely.

When Rekeying Makes Sense

Rekeying changes the internal pins so old keys no longer work while keeping your existing hardware. It's usually the cheaper option when your locks are in good condition and you simply want to invalidate keys held by previous owners, contractors, or a former tenant.

When Replacement Is the Better Call

Replace the lock when the hardware is worn, corroded, or outdated, when you want to upgrade to a higher security grade or a smart lock, or when you want all your doors to share one key and the current locks use different keyways.
