Keeping your home safe is important, and locks are a big part of that. Whether you just moved in, lost a key, or want to make your security better, you might be thinking: should I rekey my locks or replace them entirely?
Understanding the difference between rekeying and replacing locks can help you decide the best way to improve your security without spending too much money.
In this guide, we’ll explain what each option means, their pros and cons, costs, and when each is best to use.
What Is Rekeying a Lock?
Rekeying means changing the inside parts of a lock so that the old key won’t work anymore.
The lock itself stays the same, but a new key is made to fit the new setup.
Rekeying is usually done by a professional locksmith, although some lock brands offer tools for doing it yourself.
How Rekeying Works
- The lock cylinder is taken out.
- The internal parts like pins are either changed or rearranged.
- A new key is made to match the new setup.
- Once a rekeyed, only new keys can open the locks.
What Does It Mean to Replace a Lock?
- Replacing a lock involves removing the old lock pieces and installing new ones.
- This includes the whole lock system like the body and the key.
- Lock replacement is usually chosen when your current lock is broken, old, or doesn’t meet modern security standards anymore.
Rekeying vs Replacing Locks: Key Differences
Knowing the main differences between these options can help you decide what’s best for your situation.
Cost Comparison
- Rekeying is usually cheaper since you are using the same hardware.
- Replacing locks costs more because you have to buy new parts and install them.
Security Level
- Rekeying improves security by making old keys useless.
- Replacing locks lets you upgrade to more secure or smart lock systems.
Time Required
- Rekeying is quicker and can often be done in one visit.
- Replacing locks takes longer, especially if you’re doing it for multiple doors.
Appearance
- Rekeying keeps the look and style of the existing lock.
- Replacing allows you to change the look and feel of your locks.
Benefits of Rekeying Locks
Rekeying is a good option for people who want better security without spending much.
1. Cost-Effective Security Upgrade
Rekeying is much less expensive than replacing locks, making it a smart choice for people who want to save money.
2. Prevents Unauthorized Access
If someone had a copy of your key in the past, rekeying ensures they can’t use it anymore.
3. Convenient Key Control
You can rekey several locks to work with one key, so you don’t have to carry many keys.
4. Quick and Efficient
Most rekeying jobs can be done quickly without much disruption.

If your lock is broken, rusty, or not working right, replacement is a better option.
