Change Locks vs Rekeying: what’s the Difference?

Is it cheaper to rekey or replace locks?

Before diving into the costs, it’s important to understand the difference between changing locks and rekeying, as they are two distinct services:

Change locks: replacing the entire mechanism

Changing a lock involves removing the entire lock mechanism from your door and replacing it with a new one. This is often done when a lock is worn out, broken, or if you’re upgrading to a more secure lock system.

Rekeying: altering the existing lock

Rekeying, on the other hand, involves altering the existing lock so that it operates with a new key. Essentially, the lock remains the same, but the old key no longer works to open it.

So which option should I go with?

Deciding between changing locks and rekeying depends on a variety of factors:

  1. Standard or high security? If you’re looking to upgrade to a high-security lock, you’ll most likely need to replace the whole lock, however we can upgrade components on some types of locks.
  2. How’s the condition of your existing lock? If your existing lock is in poor condition or outdated, it’s advisable to replace it.
  3. Have your keys been lost or stolen? If your keys have been lost or stolen, but your lock is relatively new and high-quality, rekeying is a more cost-effective option.
  4. Have you moved into a new home? If you’re unsure who else might have a copy of your keys, rekeying is a simple and cost-effective way to secure your home.

The Cost Breakdown: How Much to Budget

Now, let’s dive into the primary concern—cost.

Cost to Change Locks

Changing a lock involves both the cost of the new lock and the labour charge for the locksmith. 

Prices can range dramatically depending on the type of door lock you’re looking to install – each locking system ranges in cost depending on the level of security, the quality of the lock and whether you’re after a digital system or restricted keying system. The cost of a residential lock is typically lower than that of a commercial-grade system. It’s best to discuss your specific security concerns and needs with a qualified locksmith that can aid in guiding you towards a product that matches your requirements and budget.

Cost of Rekeying

Rekeying is generally cheaper because you’re using your existing lock. Expect to pay labour plus a call-out fee depending on your location. Finding a locksmith close to your location is ideal in reducing the cost of call-outs.

Additional Factors Influencing Cost

  • Do you need urgent assistance? Urgent requests can incur additional charges.
  • Do you have multiple locks to rekey? If you’re rekeying or changing multiple locks, this will also impact the total cost.
  • What type of door do you have? Different types of doors require different locks, affecting the overall cost.

Extra Considerations


Upgrading to a high-security lock could potentially lower your home insurance premiums, a factor that could offset the upfront cost of the lock change. 


Smart locks are increasingly popular and provide the option to rekey the lock digitally (changing the code), which could save you money in the long run.
