1. See Figure 84. Insert the brass installation/removal key into the lock until you
hear it click into place.
2. Gently pull the brass key.
The brass key and the lock insert should come out of the lock cylinder together.
Pressing down on the brass key as you pull makes it easier for the lock insert to
come out along with the brass key.
Installing a blank lock insert
Blank lock inserts are used to cover the opening at the lock cylinder if no lock has
been installed.
1. Hold the blank lock insert so that the lug is aligned with the slot in the lock
cylinder (see Figure 85.)
2. Push the blank lock insert into the empty lock cylinder until it is flush with the
top of the lock cylinder.
3. Use the blank lock installation handle (see Figure 86) to turn the locking screw
clockwise until it reaches the bottom of the hole. Do not overtighten. The blank
lock insert is now installed.
4. Return the brass installation and removal key, aligner, and blank lock installation
handle to your supervisor for safekeeping.
