Subject: How to Restore Factory Master Code

Models: All DL2700 Locksets

If you are following the standard default procedure and the DL2700 will not restore the default Master Code (1 2 3 4 5), try varying the timing after reconnecting battery power as follows:

Step 1: Remove the battery cover (located on the inside housing assembly) and unplug the battery. Press and hold the AL key for 5 seconds, then release.

Step 2: Reconnect the battery plug, wait 1 second, then press and hold the AL key for 5 seconds. Press the default factory Master Code (1 2 3 4 5).

If the default procedure is successful , the lock LED flashes green and the outside lever engages the door latch for 5 seconds and then relocks.

If the default procedure is unsuccessful , the lock LED flashes red (with 5 beeps) and the outside lever does not engage the door latch. Repeat Step 1 above and follow Step 2B below.

Step 2B: Reconnect the battery and wait 2 seconds, then press and hold the AL key for 5 seconds. Press the default factory Master Code (1 2 3 4 5).

If the default procedure is successful , the lock LED flashes green and the outside lever engages the door latch for 5 seconds and then relocks.

If the default procedure is unsuccessful , the lock LED flashes red (with 5 beeps) and the outside lever does not engage the door latch. Repeat Step 1 above and follow Step 2C below.

Step 2C: Reconnect the battery and wait 3 seconds, then press and hold the AL key for 5 seconds. Press the default factory Master Code (1 2 3 4 5).

Repeat Step 2C until the default procedure is successful. Some DL2700 locks have a limited window of opportunity, and you must experiment a little with the timing after reconnecting the battery (in Steps 2, 2B and 2C).
