Changing or rekeying the locks? It really depends on the situation in  hand.  The number of locks, their brand and location in your property. 

How much does it cost to rekey a lock?

It seems that in the end of 2019, lock companies are less worried about patent their keyways and more about adapting a single protocol that will allow all devices work together in a smart home environment.

However, the variety of locks (Smart key, Smart lock, Commercial, residential or a car door and ignition lock) makes it hard to have a set price to the cost of  rekey. However, we’ve listed some basic questions that guide you to what we would’ve done if we were in your shoes.


If your condo/ apartment have only one or two locks – it may be cheaper and more decorative to replace the existing hardware with a new one. Most big box stores stock lock brands hardware that can be purchased for about $20 or less (set of 2 locks).


In many homes, the security door locks and french door locks are often harder to remove and requires some experience. Also, replacement hardware is more expensive than standard hardware, this is why a locksmith will need to travel to your home anyway, and it’s better to just rekey all the locks and not replace some of them.


If your house has more than 8 locks, it may be hard to find new locks with matching keys and you will end up rekeying half or more of the locks anyway. If this is the case and your locks are still useable, contact a local locksmith.

Changing Lock or Rekeying?

So, changing your locks or rekeying them, which is better? By the end of the day it’s your decision. It’s about functionality, availability, decoration and of course cost. As long as you have a working key to your lock, rekeying it will be the preferred method from a locksmith point a view. However, if your locks are old, it may be a good idea to upgrade some or all of them. You can always consult your locksmith on site and learn about more options other than rekey.

Remember that a good lock can last 30 years and more and replacing a good working lock may not be required in order to rekey your home.
