Rekeying VS Changing Locks- Which One Is Best?


We all want to lead a secured life. Apart from all other things, our home’s locking system is a vital part of ensuring that security.

Sometimes it just requires changing a key, and sometimes you may need to change the lock. If you want to know rekeying VS changing locks- which one is best, then you have to read the writing. As here, we are going to converse about both along with some other factors.

Difference Between Rekeying VS Changing Locks

Before dig into the deep, you have to have a vivid idea about the difference between the process. So let’s know the difference between them.


In rekeying, you will keep the same locking system but will change the key to another key, which fits in the lock. To elaborate, the lock will remain the same, but the inner system of the lock will be altered so that a new key can be used.

A professional locksmith will change the internal pins and springs in the lock cylinder at the time of rekeying. If you look at the key, you will see the ridges, and those are markings that represent the appropriate lock’s internal pins and springs.

Arrangement of those parts matches the key, which led to unlocking the door. In the rekeying process, those parts are rearranged in the lock cylinder. After rearranging, the previous key won’t work anymore, and a new key can be fitted.

For rekeying, the present key should be along with you. If you have lost the key, but you have one spare key, or someone from your family has the duplicate key, it will work as well.

However, without the original key rekeying can be done. But it will cost you more.

Changing Locks

On the contrary, changing a lock requires an entirely different process. Here, the whole lock will be removed physically. The locksmith will unscrew the lock, then remove the deadbolt and lock mechanism and install a new lock at the place of the previous one.

Rekeying a lock is more affordable instead of replacing it. Sometimes, at the time of rekeying, it can provide you hint if replacing the lock is needed.
