Rekey vs Replace Locks: Which Should You Choose?

Updated October 16, 2026 · 5 min read

Rekey vs replace locks comes down to the hardware: rekey a working lock when you need different keys, and replace it when you need new hardware or the lock is damaged. Both options can help you manage who has access to your home or business.

Rekey vs Replace Locks: What Changes?

Rekeying changes the lock so it works with a different key, while keeping the existing lock hardware in place. The old key no longer operates that lock after the rekey. This is often a practical choice when the lock itself is working properly and you want to prevent someone with an old key from using it.

Replacing a lock means removing the existing hardware and installing a different lock. You might choose that option when the lock is damaged, worn, or you want different hardware. The decision is not simply about getting a new key: consider the lock’s condition and whether you want to keep the hardware you already have.

Choose Rekeying When the Lock Works and You Need New Keys

Rekeying can suit everyday situations where you want to change access without replacing a working lock. For example, after moving into a home, you may not know who still has copies of the existing keys. Rekeying lets you use new keys while keeping the lock hardware in place.

It can also be worth considering after a key goes missing or when you no longer want someone with an old key to have access. Think through every exterior door and any other locks you want included, so you can explain the scope clearly when you request service.

• You want to keep the existing hardware — If the lock operates properly and you like it, changing the key may meet your needs without replacing the lock.
• You want to stop using old keys — A rekey changes which key operates the lock, which is useful when you no longer want to rely on keys that may be out of your control.
• You want to address several locks — Make a list of the doors and locks you want handled. Rekeying is priced per lock, so a clear count helps you discuss the job.

Replace a Lock When the Hardware Needs to Change

A new key will not repair a lock that is physically damaged or worn out. If the lock is cracked, loose, or no longer operates reliably, replacement may be the more suitable option. Tell the locksmith what the lock is doing, rather than assuming a rekey will solve a mechanical problem.

Replacement also makes sense when you want different hardware, not just a different key. You may be updating the look of a door or choosing a lock that better fits your needs. If you are unsure, describe the lock’s condition and what you want to change; that gives you a useful starting point for deciding between rekeying and replacement.

Compare the Cost of Rekeying and Replacing a Lock

For lock rekeying, the starting price is $65 per lock. A lock change starts from $95 plus hardware. The right comparison depends on what you need done: rekeying keeps the existing hardware, while a lock change includes new hardware in addition to the service.

If you’re comparing the locksmith cost to rekey a lock with the cost of replacement, count the locks involved and be clear about whether any hardware needs to change. Ask what the locksmith rekey price covers and whether the work you describe calls for rekeying or a lock change. We tell you the price before any work starts, so you can decide with the details in hand.

People searching for rekey locksmith cost often want one number, but rekeying is priced per lock. Share how many locks you want addressed and explain their condition when you call. For the lock rekeying service, we can discuss your needs and the price before work begins.

Prepare for the Locksmith Visit

A little preparation helps you explain the problem and get a clear answer about the next step. You do not need to diagnose the lock yourself. Note what you want changed and share any symptoms you have noticed.

Before the work starts, confirm the requested service and price. If you are comparing rekey cost with a locksmith against replacing hardware, ask about each option for your specific lock rather than assuming they are interchangeable.

1. 1. Describe the situation — Say whether you have lost a key, moved into a property, want to change who has access, or have a lock that is not working properly.
2. 2. Identify the locks — Tell us how many locks you want addressed and where they are, such as at your home or business.
3. 3. Ask about the right service — Explain whether you want to keep the hardware or replace it. A locksmith can discuss the choices based on the condition and type of lock.
4. 4. Confirm the price first — We share the price before work starts. Review the quoted service and scope before deciding how to proceed.

Make the Choice Based on Your Lock and Your Goal

If the lock works and you mainly want to stop using existing keys, rekeying is the option to ask about first. If you want new hardware or the current lock is damaged, ask about a lock change. A locksmith can help you understand which service fits the condition of the lock and the change you want.
