Rekey vs. Replace Your Locks: Which Do You Actually Need?

When you need to change who can get into your home, you have two options: rekey your existing locks or replace them entirely. Both secure your home — but they solve different problems and cost different amounts. Here's how to choose.

When rekeying is the right call

Rekeying keeps your current hardware and simply changes which key works. Choose it when:

• You just moved in and want old keys deactivated
• You lost a key or a former roommate or tenant still has one
• Your locks are in good working condition and you like them
• You want to save money — rekeying is almost always cheaper

When replacing makes more sense

Replacing swaps out the whole lock. Choose it when:

• Your locks are old, worn, sticking, or damaged
• You want to upgrade to higher-security or smart locks
• The finish or style no longer matches your door
• The lock has been tampered with or forced

A simple way to decide

Ask yourself one question: is there anything wrong with the lock itself? If the lock works fine and you just need new keys, rekey. If the lock is failing or you want an upgrade, replace. When you're unsure, a licensed locksmith can assess it in minutes and recommend the option that actually fits — not the one that costs the most.
