Soep 7:
Identify the mounting location for the key lock assembly.
Two threaded mounting holes are provided in the mounting tab to
accommodate the two mounting screws (E) and two fiber retaining
washers (F), which serve as spring washers when tightened. Make
sure the key (B) is removed before mounting the assembly. Position
the key lock assembly and tighten the two mounting screws. Make
sure the mounting bracket’s sheet metal tab is positioned under the
plastic of the pushbutton plate. Use a small flat screwdriver to get the
metal tab under the plastic.

back into place.

With the key lock assembly now installed, place the front
cover previously removed in Step 2 on an appropriate work surface
front side up. Put a rigid support under the round knockout window.
Using a small punch and a hammer, carefully punch out the round
window in the upper center portion of the front cover. If necessary,
use a small file to remove any burrs from the window. Make certain
that all pieces and/or particles are cleaned up and removed before
proceeding.
Soep 10:
Replace the front cover, and secure it in place with the
mounting screws previously removed in Step 1. Remove the adhesive
backing from the external protective ring (A), and press it onto the
front cover over the key lock.
