The audit log contains the last 1,500 access attempts with date, time, access granted or denied, and user name. When a valid credential is detected, the green LED illuminates, the latch retracts for the default time of five seconds, and there is a positive confirmation beep. If an invalid credential is entered, the red LED illuminates, and there is a negative beep.

NOTE: There is a five minute lockout after multiple invalid attempts.

The time-based parameters are a week in length, with half-hour increments incorporating one window per day. For convenience, a window can wrap one day into the next day. The dual credential requirement can require one person to enter two credentials or two persons to each enter one credential. The second credential must be a P.I.N.

The eLock is designed to be wired using plug-in connectors. There are five sockets in the rear of the electronic lock -- a 2.5mm optional external power supply connector, latching mechanism, battery pack, RJ11 remote programming port, and optional alarm module socket.

For the purpose of this article, we installed a proximity reader/keypad eLock with battery pack into a metal gun cabinet. The gun cabinet was equipped with two recessed tubular locks, each operating a metal locking bar. The tubular locks were removed. An oak board was installed and machined to provide a surface for the latching mechanism. Two stove bolts secure the oak board. The heads of the stove bolts were slid into security collars to maintain the clean appearance and resist forced removal.

To install the eLock:

  1. Remove the tubular locks.
  2. Cut wood to size. The length dimension was 47-1/2”.
  3. Locate recesses in door and use them as a template.
  4. Determine centers.
  5. Cut approximately 1/2” using 2-1/8” hole saw.
  6. Use laminate trimmer to remove wood. Take two passes because the tool is removing oak.
  7. Drill 3/8” diameter hole for stove bolts.
  8. Secure board into door using the fender washers and the nuts.
  9. Remove material for the latch mechanism to be flush with the interior of the door. Take two passes because the tool is removing oak.
  10. Install the 3” by 5” Strong Tie plate.
  11. Locate the openings for mounting the keypad and running wiring.
  12. Cut the openings.
  13. Remove the four Phillips head screws securing the mounting plate onto the keypad.
  14. Insert two 2-1/2” long 3/32” screws into the base.
  15. Secure the screws to the base using nuts.
  16. Reattach the base using the four Phillips head screws. Check to make sure the screws will slide into the drilled holes in the door.
  17. Enlarge the drilled holes in the door to 5/32” diameter to accommodate the nuts enabling the keypad to mount flush to the door.
  18. Insert four “AA” batteries into the battery pack.
  19. Connect the wiring from the keypad to the battery pack, latch mechanism, and RJ11 port.
  20. Secure the keypad to the outside of the door.
  21. Use the provided double stick tape to secure the battery pack to the inside of the door.
  22. Mount the latch mechanism. Test the operation of the eLock.

The CompX eLock is shipped without any Supervisor or User codes programmed into the lock. To test the operation of the eLock, there must be a Supervisor code within the system. The Supervisor code that is used to enter the programming mode cannot be deleted. The first Supervisor code programmed is in slot #001.

To program the first Supervisor Code:

  1. Press and hold the “#” key until the beeping stops.
  2. Input a Personal Identification Number or a Supervisor Card and press the “#” key. This P.I.N. or card is supervisor in slot #001. Test the operation of the #001 Supervisor.
