Troubleshooting
1. Check door for proper installation (see pictures to the right). Verify
1/8" between the latch and strike.
2. Check hinges. They should not be loose or have excessive wear on
knuckles.
3. If Latchbolt will not deadlock:
Either strike is out of line or gap between door and jamb is too great.
Realign strike or shim strike out towards flat area of latchbolt.
4. If Latchbolt does not retract or extend properly:
Latchbolt tail and retractor may not be properly positioned.
A. Remove lockset. Look through 2-1/8" hole and verify latchbolt tail
is centered between top and bottom of hole.
B. Remove latchbolt and insert lockset. Look through latch hole and
verify retractor mouth is centered in hole. Adjust outside rose
plate if not. (See #5 on page 2)
C. Rebore holes if necessary to line up retractor and tail.
