In some cases locks do fail or break, and it is important to replace them quickly and correctly in order to protect your home. The starting process is similar to removing the knob or handle in lock rekeying, except that in this process the rose and spindle (the rod connecting the lock on one side of the door to the other lock on the opposite side) will be removed from the door.
The bolt will also be replaced by unscrewing the bolt guard (also known as housing) and removing the bolt. Once this is done, the holes may need to be adjusted depending on the difference of the new or desired lock. The reassembly is a cautious reversal of the disassembly process, with special attention kept to the fitting of the internal mechanisms. With the new lock installed, the homeowner can rest easy knowing that their locks will open and close as desired, and keep the building and its residents safe.
