The white cable connector has two ridges that should be facing outwards and the cable connector should snugly fit into the adapter located on the interior side of the lock. [This video](https://www.youtube.com/watch?v=KP1LkA21Glk) can help.

If the battery is low, a series of warning beeps will sound and the Assure Lock will also provide you with a visual low battery warning after a valid code has been entered. The lock operates as normal immediately following the alerts. The critical battery indicator causes the Assure Lock to flash red and the lock does not operate. **For YRD410 or YRD420:** In the event the batteries die, you can unlock the door with your mechanical key backup. **For YRD430 or YRD 450:** In the event the batteries die, you can touch a 9V battery to the terminals on the front of the lock.
