What is the difference between rekeying and replacing a lock?

# Rekeying vs. Replacing a Lock

Rekeying means a locksmith changes the internal pins inside your existing lock so it works with a new key. The lock body stays in place—only the mechanism is altered. This is usually the cheaper option ($50-$150 per lock) and works great if your lock is in good condition but you want to change who has access (like after moving or losing a key).

Replacing means removing the old lock entirely and installing a new one. You'd do this if the lock is damaged, broken, outdated, or if you want a different style or higher security level. This costs more ($150-$300+ per lock) but gives you a fresh lock with new keys and potentially better features.

When to rekey: You moved into a place and want new keys, you lost your keys, a tenant moved out, or you want to match multiple locks to one key.

When to replace: Your lock is broken or worn out, you want to upgrade security, the lock is incompatible with your needs, or you prefer a different look.
