Find the two tabs on top of your keypad, press them in to release the cover and gently pull the keypad toward you.
Quickly inspect the old battery. If the battery looks abnormal (i.e. has a swollen or split case, liquid leaking from the case, or corroded terminals) close the keypad and call (800) ADT-ASAP to schedule a service call.
Remove the small screw from the plastic battery bracket. Be sure to put the screw in a place where you won’t lose it since you’ll need it later.
Gently remove the wires from their retaining clips, and then disconnect the battery wires by pulling on the plastic connector.
Then tip the top of the battery up to remove it from the compartment.

Thread the wires under the retaining clips, remove the protective plastic from the connector, and plug it into the receptacle.
Replace the keypad, the two tabs snap back into place, and then plug the transformer back into the outlet.
Check your alarm keypad to ensure it no longer displays the “BAT” or “SYSTEM LO BATTERY” message. If it still shows a low battery message, try entering your code and pressing the OFF button. Repeat if necessary. If the message still shows, it may take 24 to 48-hours for the battery to fully charge. If after 48-hours the message still shows, please go to MyADT.com and start a Chat Session with us, or call (800) ADT-ASAP to troubleshoot your system.
When the message is gone or you’re waiting for the battery to charge, remove your system from Test Mode at MyADT.com.
