Low Battery Warning

The ESL5 and ESL5LP locks provide a warning when the battery is getting low.

When the battery power drops to a near critical level, after a normal lock opening cycle is completed, a low battery warning warble tone will sound for 3 seconds and the keypad LED(s) will flash. The lock will not open soon. Change your Battery!

Weak or Dead Battery

This is the #1 cause of opening issues. Symptoms of a low battery can include lack of keypad response to input or lack of bolt actuation (clicking sound) after inputting your combo. The ESL5/ESL5LP does not have a low battery indication.

The ESL5/ESL5LP uses a 9-volt alkaline battery. The simple and reliable nature of the ESL5/ESL5LP is centered on a large Solenoid that requires high current delivery very quickly. Batteries that may appear to have a good charge level may not have the capacity to deliver high current as they decay. Low quality batteries tend to show poor performance when they are placed in demanding conditions like this.

If you have changed your battery, and there is still no keypad response to input:

  • Remember to first press “C” when entering your combination
  • Make sure the cable has not become disconnected from the keypad. Remove the keypad and check the connection to make sure the cable is securely installed in the socket. The locking tab should engage, so that pulling on the cable will not dislodge the plug
  • Make sure the Battery Contacts snap firmly onto the battery posts. A loose connection cannot deliver high current.

Replacing the Battery by model

Always use a fresh name-brand Alkaline Battery for best results.

ESL5 Locks (Round Keypad)

  1. Grip the keypad and rotate approximately 1/8 turn counter-clockwise to disengage the keypad from the base.
  2. Carefully pull the keypad away from the base, taking care to not stress the cable that connects the keypad to the lock inside the safe. Do not allow the keypad to hang on the cable.
  3. Lift the 9-volt battery out of the pocket where it is retained.
  4. Carefully remove the battery clip from the end of the battery, making sure you don’t pull on the wires and disconnect the battery clip from the PC board.
  5. Snap the new 9-volt battery onto the clip, making sure it is tight with no loose contacts.
  6. Press the battery back into the battery holder pocket, taking care to route the wires in the open cavity so they are not positioned where they will get pinched under the battery when the keypad is placed on the base.
  7. Replace the keypad on the base, starting with the top of the keypad around the 11:00 position, pressing down to seat it where the three retaining tabs go into the receiving slots, then rotate clockwise to vertical. You should feel a bit of a snap as it locks into position when the keypad is level.

ESL5LP Locks (Long Keypad with integrated Handle)

  1. Slide the Battery Door on the bottom-right corner of the Keypad to the Right to expose the battery.
  2. Lift out the old battery.
  3. Place the new battery in the battery cavity.
    Note:The larger (minus) battery terminal is on top. Make sure both of the battery tabs are clean and making a good contact with the battery’s terminals.
  4. Replace the Battery Door over the battery, and slide it to the left until it’s seated.
