The code doesn’t unlock the door.
  • Press the “C” (clear) key and enter the passcode again.
  • Ensure that each key (including the “C” key) has been fully pressed.
  • Remove the lock and the lock code plate to ensure that each letter/digit in the chosen code is represented by a red code tumbler and all other code tumblers are blue.
  • Remove and reinsert the code tumblers, ensuring that they are correctly oriented and fully inserted.
The latch lever turns, but the latchbolt does not retract
  • The spindle used is too short for the door’s thickness. The spindle must be long enough to simultaneously engage both the interior and exterior levers. Use a longer spindle.
