Re-Keying Your Front Glass Door Swing Bolt Lock

If you have a a #2 Phillips head screwdriver and a small flat head driver, then you can re-key your own front glass door. When I say "re-key", I mean removing the round cylinder and replacing it with a new one. Go to your better hardware store, not Lowe's, and ask for a 1 inch mortise cylinder with the Adams-Rite Cam. Have extra keys made and test them. Here are the steps in the change-out process

1. Remove the lock face plate on the side of the door. Usually held in with three Phillips head screws.
2. Look for two more Phillips head screws, one at the top of the lock and one at the bottom. Loosen these just enough so that the bolt body wiggles a bit.
3. Look for two sunken flat head set screws opposite each lock cylinder. Look closely. Each cylinder will have one. (Your door does have two cylinders, one inside, one outside.) Loosen these by about three turns, just so you can grab the cylinder you are changing and unscrew it.
4. Unscrew the lock cylinder. You will notice from the new one you purchased that the cylinder is threaded.
5. Take the spacer off the old lock and put it on the new one. Reinstall lock.
6. Do note that, if you screw the lock in too far, the cam may bottom out on the Adams Rite bolt workings inside the door. If you do this, you will feel the key grind as you turn it. If it is grinding, back the cylinder off by one turn.
7. Options you can add to this job are lubing the inside of the Adams Rite and adding an anti-wrench collar in place of the standard collar.
8. Reinstall the set screws, tighten the two top and bottom screws, reinstall the face plate. You just saved yourself $70.
