What’s the Difference Between Rekeying and Replacing a Lock?

If you’re a homeowner in Phoenix trying to improve your home security, you’ve probably asked yourself: Should I rekey my locks, or replace them completely?

It’s a great question—and the answer depends on your goals, your budget, and the condition of your current hardware.

At Affordable Security Locksmith And Alarm, we help homeowners make the smart choice between rekeying and replacing every day. Here’s how each option works, and when it makes sense to use one over the other.

What Is Rekeying a Lock?

Rekeying means we change the internal pins inside the lock cylinder so it works with a new key. The outside of the lock stays exactly the same—no need to buy new hardware.

It’s perfect if:

• You’ve lost a key
• You’re moving into a new home
• A roommate or contractor had access
• You want one key to open all doors

Rekeying is fast, affordable, and just as secure as changing the whole lock—as long as the existing lock is in good condition.

What Does Replacing a Lock Mean?

Replacing means removing the entire lock (handle and/or deadbolt) and installing a brand-new unit.

This is a better choice if:

• Your current locks are worn out or damaged
• You want to upgrade to smart locks or keypads
• You want a different style or finish
• Your lock doesn’t meet modern security standards

Lock replacement gives you a clean slate—and in many cases, better long-term durability and protection.

Cost Difference: Rekey vs Replace

In most cases:

• Rekeying costs less because you’re only changing the internal components
• Replacing is more expensive, but includes all-new hardware

Many Phoenix homeowners rekey when they first move in, then upgrade or replace their locks later once they’ve settled in or begun renovations.

Which Option Is Better for Security?

Both options restore security. But…

Rekeying resets access—good for when you’re worried about who might have a copy of your old key.
Replacing adds features—like anti-pick pins, stronger hardware, or keyless entry.

If your current lock is in good shape and offers decent protection, rekeying is usually fine. But if you want to level up your home security, replacing is the better choice.

Still Not Sure? Let a Phoenix Locksmith Help You Decide

We can inspect your current locks and recommend the best path based on:

• How old your hardware is
• Whether it’s compatible with other doors
• What your security goals are
• Whether you’d benefit from upgrading to smart or high-security locks
