- Walk over to one of the businesses next to you and observe the position of the cylinder. You will note that the key insertion point is probably at the 6 o' clock position exactly. (Some door have in at 12 o' clock, but it is rare.) Also, make sure you are not looking at a door on the business where the lock cylinder has been turned upside down in order to disable the key operation on the outside. If in doubt, ask the store manager.
- Open your door and look on the door edge and you will see a cover plate with three screws in a vertical line. Using a screwdriver, remove these screws and remove the plate.
- Look for a small, black set screw that sits flush into the lock, right next to the cylinder that is loose. Back the screw out counterclockwise two turns, but do not remove it.
- Grab the cylinder. It is a threaded lock cylinder and it screws in and out like a regular screw. Turn the lock to where the key insertion point is sitting right a 6 o' clock. Tighten set screw. While you are at it, tighten both. You will see them side by side. Replace plate.
- Since you are servicing the lock, take WD-40 and shoot the key hole. Also, with the deadbolt in the partially "out" position, angle the WD-40 can into the bolt hole and aim in up into the lock where you guess the back of the lock's key cylinder would be.
