Whether you just moved into a new house or have been in the same house for quite some time, one of the many things people recommend you are either changing your locks or re-keying them. However, understanding the difference between these two and what proves to be more suitable to a given requirement can be challenging, especially if you have no knowledge about them. Here is a brief guide on what you should go for when it comes to re-keying or replacing locks in your house.  

When Is Re-keying Suitable 

Re-keying is simply where you keep the same lock that you have but alter its mechanisms in a way that will work only with a new key. So with re-keying you will only have to get a new key that works with the re-keyed lock. 

Re-keying is done in a lock by replacing certain mechanisms, mainly pins and springs that are found in the lock cylinder. In every lock, there are a series of key pins, and each of these will correspond to a key. Only when they match a key will they be able to unlock a door. So when you re-key i.e. change the pins in the lock you will need a new key to open the door. 

In most cases re-keying is the most suitable option for the following, 

  • If all your house locks are of the same brand or have the same keyhole but use different keys, then you can re-key your locks to be opened using one common key. 
  • If you have lost your key and fear someone will have access to your house then you can rekey your locks. This will make the lost key obsolete. 
  • If you move into a new house that had tenants or owners before you, or if a roommate of yours who had a spare key for the house left the accommodation, then rekeying is a way to guarantee that no one except you and your family has access to the house. We never know how many people have copies of the original lock or got spare keys from the house owner. 
  • Re-keying is a good option if you’re looking to tighten the security of your home without changing the existing interior statement. The same can be done if you don’t want to change the locks for sentimental or heritage reasons, but want to tighten security.  

Compared to lock replacement, re-keying is cost-effective, simple and efficient. However, it should not be mistaken for key duplication

When Is Changing A Lock Suitable 

Changing locks is pretty straightforward, it’s basically changing the locks completely to a new one. In the case of a lock change, the lock will be changed and you will also need a new key, unlike in rekeying where the lock isn’t replaced but altered with only the requirement of a new key.  

Compared to re-keying, the cost for lock replacement is a little higher and takes time as you need to search for locks that will match your interior style and a locksmith has to remove the old lock and related hardware and install new ones.

In some cases, lock replacement is more sensible than re-keying for the following reasons, 

  • If your current lock security is outdated or if you feel it’s not secure enough, then it’s best to change the lock and go for more advanced locks. 
  • If you feel the condition of the lock is weak enough to break easily or if it’s heavily damaged, then a lock replacement is the best option. It’s the same if your current locks are not that easy to operate, or are worse for wear.
  • If all the doors in your house have different lock brands and you want to open all of them using a single key for convenience, then a lock replacement is suitable. 
  • You can also consider changing your lock if you lost your key, experienced any recent break-ins, thefts or similar incidents that put the security of your house at risk. 

As you can see, whether or not you should go for re-keying or lock replacement depends on your requirement and other budget, interior, and security preferences. Once this is defined, deciding which one to choose is simple and straightforward.
