CM Series lock (old locks)
- The battery compartment is located under the interior latch, secured by four Philips head screws, one at each corner.
- Remove all 4 screws while carefully holding on to the back of the lock so it doesn't fall.
- Carefully pull the piece off of the door.
- This is most easily done with the door closed.
- When you do this, you are locking yourself in the room. Don't freak out.
- The piece you are removing will look like this.
- The part remaining on the door will have a square hole that should have a peg with a spring on it. Sometimes the peg will fall out. Some of the doors are missing the spring.When you put it back in, make sure the rounded end is outward facing.
- Remove the old batteries and replace with new ones.
- Fit the back panel back, being careful to line up the peg and spring. Then replace the screws.
- Take care to sink the screws properly; if you don't, the threads inside the panel will be stripped, and the screw will not screw in completely. It may also cause damage to the panel.
- A good trick is to put the screw in by hand, turn it counter-clockwise until you feel the screw slip into place. Then carefully turn the screw clockwise by hand a rotation or two to properly thread the screw.
- Finally, pull on the handle to make sure that the latch engages. If it doesn't, remove the back panel again and check whether the batteries and the spring and pin are in correctly.
This final step is very important because if not done properly, patrons can get locked in the room. (eek!)
