One of the services that residential locksmiths tend to offer is a residential lock rekey. This is a common service that residential locksmiths generally engage in, and is incredibly easy for a trained professional to do. Many times, professional locksmiths get calls from customers saying that they want their change the locks in their home. However, they don’t often realize that the better solution is to rekey, let alone actually know what rekeying is. A residential rekey is a process in which a professional remove the springs and internal mechanisms of the lock, but not the entire unit as a whole. The springs and pins of the locks and removed and new ones are put in its place. The kind of rekeying that is done generally depends on the lock being used, and a well trained professional is generally able to rekey almost any kind of system that one has in place.
Once the changes have been made, a new key has to be made to fit with the lock. The reason for this is because once a rekeying is done, all the old keys would not be able to open the lock at all. A lock and key are meant to fit well with each other, which leads to the effect of it being ‘opened.’ Rekeying changes the grooved on the lock, thereby making it so that a new key that fits better with it needs to be used. The lock in this instance works like it is completely new, even though you haven’t actually taken out the entire piece.
