One of the most common questions we get is: "Do I need to replace my locks or can I just rekey them?" The honest answer is that most of the time, rekeying is all you need — and it costs significantly less. But there are situations where replacement is the right call. Here's how to tell the difference.
What Is Rekeying?
Rekeying changes the internal pins inside your existing lock cylinder so the old key no longer works. A locksmith disassembles the lock, swaps out the pin tumblers, and reassembles it with a new key combination. Your lock hardware stays exactly the same — only the key changes.
Cost: typically $20–$40 per lock. Time: 15–30 minutes per lock on-site.
What Is Lock Replacement?
Lock replacement means removing the existing hardware entirely and installing a new lock. This costs more — both for the hardware and the labor — but it's the right move when the existing lock is damaged, worn out, or you want to upgrade to a different type of lock entirely.
Choose Rekeying When...
- ✓ You just moved into a new home or apartment
- ✓ You lost a key and want to make it useless
- ✓ A roommate, employee, or contractor no longer needs access
- ✓ You want all your doors on one key
- ✓ Your locks are in good working condition
- ✓ You want to improve security without the cost of new hardware
Choose Replacement When...
- ✓ The lock is damaged, worn, or no longer functions smoothly
- ✓ You want to upgrade to a smart lock or keypad entry
- ✓ The lock was forced or tampered with during a break-in
- ✓ You want a higher-security grade lock than what's installed
- ✓ The lock brand is old and parts are no longer available
- ✓ You're replacing the door itself
The Bottom Line
If your lock works fine and you just need to change who has access — rekey it. If the hardware itself is the problem, or you want a completely different type of lock — replace it. When in doubt, a quick call to a local locksmith will give you a straight answer and a price for both options so you can decide.
