Rekeying vs Replacing Your Locks: What’s the Best Choice?
If you’ve recently moved, lost your keys, or had a security scare, you’ve probably wondered: “Should I rekey my locks or replace them altogether?” It’s a common question—and an important one.
At MVLocksmith Services, we help customers make this decision every day. Here’s a simple breakdown of what each option means, when to choose one over the other, and how to make the best choice for your situation.
What is Rekeying?
Rekeying involves changing the internal pins inside your existing lock so it works with a new key. The lock stays the same on the outside, but old keys will no longer work.
Benefits of Rekeying:
Keeps your current hardware (no need to change the actual locks)
More affordable than full lock replacement
Faster service—usually done in one visit
Great for key control (like when you’ve handed out too many copies)
When to Rekey:
You’ve moved into a new home
A roommate or tenant moved out
You lost a key
You want all your locks to work with one key (if compatible)
What is Replacing Your Locks?
Replacing a lock means removing the entire lock mechanism and installing a new one. This gives you the opportunity to upgrade your security or change your lock style.
Benefits of Replacing:
Improved security with newer or higher-grade locks
Option to upgrade to smart locks or keypads
Solves issues with damaged or worn-out locks
Great for home renovations or aesthetic updates
When to Replace:
Your current locks are old, rusty, or malfunctioning
You want to upgrade to smart locks
You want a different style or finish
Your existing locks are low-security or easily picked
