If you've moved into a new place, lost a key, or just want peace of mind, you'll usually be choosing between two options: rekeying or replacing your locks. Here's the actual difference.
What Rekeying Does
Rekeying keeps your existing lock hardware in place and changes the internal pins so your old keys no longer work and new ones are cut to match. It's a faster job, and it's usually more affordable than a full replacement — a smart move after moving into a new home, after losing a key, or after a roommate or tenant moves out.
What Replacing Does
Replacing means removing the entire lock and installing new hardware. This makes sense when your current locks are damaged, outdated, or you want to upgrade to a different style, brand, or security level (like a high-security or smart lock).
When to Choose Rekeying
- You just moved in and don't know who else has a key.
- You lost a key or had one stolen, but the lock itself is in good shape.
- You want one key to work across multiple doors (keyed-alike).
- You're working with a tighter budget.
When to Choose Replacing
- Your current locks are damaged, worn out, or frequently jamming.
- You want to upgrade to a higher security grade or a smart lock.
- You want a different style or finish to match new doors or renovations.
Not sure which one fits your situation? A locksmith can usually tell in a couple of minutes by looking at the hardware. See our pricing guide for typical costs on both options.
