Mechanical Keypad Door Lock

The SECO-LARM Mechanical Keypad Door Lock provides secure locking while avoiding the hassle and cost of dealing with providing, duplicating, or replacing keys. Unlike keyed locks, the lock code can be easily changed by the user at any time. The code is not sequential, so the code letters/digits can be entered in any order. Since it is completely mechanical, there is no need to run wires from a power supply or replace batteries. The inside handle always operates to allow safe egress in an emergency.

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.
