Commercial lock change is a common maintenance task, but you shouldn’t treat it lightly. It is not only a way to make sure that you are the only one who has access to your office space, but it can also protect inventory and equipment in your business. In addition, if you have a tenant move out or you find that an employee has been keeping the key, it is important to replace the lock as soon as possible.
The first step in commercial lock replacement is to remove the existing latch. This can be done by unscrewing the through bolts on the interior side of the door. You will see a small hole where the latch meets the door, and your new lock will come with a tool with a pointy end that you can poke into this to release a springed clip that allows you to pull the handle off. If the poke tool that came with your lock isn’t long enough, you can use a strong toothpick or the end of a wire coat hanger.
Next, you will need to remove the faceplate of the lock. Unfasten the two screws that hold this on the inside of the door with a screwdriver. If you are replacing the same type of lock, you will likely be able to keep your latch plate and strike plate as well. If you’re switching to a different type of lock, double-check the cylinder dimensions and cam shape as well as the set screw length.
