The ADT keychain remote is a small wireless fob that arms and disarms the system and sometimes sends a panic or status signal, and before it works it has to be enrolled with the control panel. The panel stores each fob as a device, so pairing is done at the keypad, not on the fob. Enter the panel's programming mode, which usually needs the installer or master code, go to the device or key fob enrolment option, and press the fob's button when the panel asks for it;
The checks in more detail
the panel beeps or shows a message when it has learned the fob. SafeWise notes that the key presses differ by panel model, so find the model in your online account or on the panel before you follow a sequence you found online. Give the fob a user number or a name so that the panel's history shows who armed or disarmed the system, which matters when several people use fobs. If the fob will not pair, start with the battery:
a fob that has a weak coin cell sends a weak signal or none, so fit a fresh one of the type printed in the battery compartment, with the positive side the right way up. Hold the fob close to the panel while pairing, because the enrolment signal is short range, and press the button once firmly and wait for the panel's response. A fob already enrolled on another panel or user number may need to be deleted first.
After enrolling, test it with the panel in the state you use: arm, disarm and check that the panel responds, and tell the monitoring company if you will use the panic button so that they know it is live. Do not leave a fob in a car that is easy to break into, because it can disarm the system, and delete a lost fob from the panel at once. If a pairing fails on a fresh battery, ask the installer to check the fob and the panel's receiver.
