Rekeying a door lock is a straightforward process that can be completed in a few simple steps. To start, insert the key into the lock and turn it a quarter of a turn to the right. Then, use the removal tool included in the kit to press the clip that allows you to remove the knob from the spike. The next step is to determine if the locks have the same key holder. To do this, take the key you want to use and check if it slides through the hole in the new lock.
If it slides inward, then you can rekey the locks to match each other. However, if the key is not inserted, then it means that the cylinders (keys) are different and the lock cannot work with that key. Once you've established that the locks have the same key holder, you can rekey them so they use one key. This will make it easier and more convenient for you to access both locks with one key.
