How Rekeying Works and When You Need It

Rekeying is one of the most requested locksmith services, but many homeowners don't fully understand how it works.

How rekeying works: Inside every pin tumbler lock is a series of spring-loaded pins of varying heights. Your key is cut to specific heights that align these pins perfectly, allowing the lock to turn. When a locksmith rekeys a lock, they change the height of these pins so that old keys no longer work — and new keys are cut to match the new pin configuration.

This process doesn't require replacing the lock hardware itself — only the internal pin configuration changes. That's why rekeying is much more affordable than full lock replacement.

When to rekey: Moving into a new home, losing a key, after a breakup or roommate change, when an employee with key access leaves your business, or after a security incident.

Rekeying vs. replacing: If your lock is in good condition, rekeying provides the same security benefit as replacement at a much lower cost. However, if the lock is damaged, worn, or you want to upgrade your security level, replacement makes more sense.
