When the integrity of a door lock is compromised what comes to most people’s mind is changing the locks. Many are not aware of the process of rekeying a lock. While most people will opt to change the locks completely, rekeying is another viable option. Each of these processes have their pros and cons. Below is a detailed description of each and their pros and cons.

Rekeying: What it is?

Rekeying describes a process of adjusting the internal workings of a lock such that the old key no longer works for it. A new key would be used for the adjusted lock without compromising the lock integrity. This may sound simple, but it is not. It requires the skills of a professional locksmith. Rekeying is cost-effective as it makes use of the existing lock body.

In order to rekey a lock, the lock cylinder must be unmounted from the door and then the key pins must be rearranged or changed in order to fit with the new key. The new key must be in hand during the rekeying process and an understanding of the way key pins work is needed. Pin sizes are meant to match key depth. A key decoder is very useful for this process. Below are a few pros and cons of rekeying;


1. Cost effective:

This is the number one pro of rekeying over changing locks. When it comes to rekeying, the only thing that needs to be changed are the key pins, which are very inexpensive, particularly when compared to buying a completely new lock. Rekeying is the best option for homeowners who would like to change their home security but who wouldn’t want to spend too much on it. The only cost involved is the labor cost of having a locksmith over.

2. Quick and easy:

When handled by a professional, the process of rekeying can be quick and easy. It doesn’t require so much manpower or tools. All that is needed is a key decoder, a spanner, a catching tool and the new key that is to be used.
