What is the difference between rekeying and changing locks?

# Rekeying vs. Changing Locks

Rekeying means changing the internal pins of your existing lock so old keys no longer work—but you keep the same lock hardware. A locksmith removes the lock cylinder, rearranges the pins, and provides you with new keys that fit the altered mechanism. It's a quick, affordable option that works well if your locks are in good condition.

Changing (or replacing) locks means installing completely new lock hardware. This is ideal if your locks are damaged, outdated, or you want upgraded security features (like smart locks or higher-grade deadbolts). It costs more than rekeying but gives you fresh hardware and modern options.

When to choose each: - Rekey if you've lost keys, moved into a new home, or had a tenant move out—and your current locks work fine - Replace if locks are broken, you want a security upgrade, or you're changing your aesthetic

Most locksmiths can do both. Rekeying typically costs $15–$40 per lock, while replacement runs $50–$200+ depending on the lock quality. Get quotes from a few local licensed locksmiths to compare pricing for your specific situation!
