How to fix a Honeywell Security System keypad that is locking up after 3-4 button presses?

If your Honeywell Security System keypad locks up after a few button presses, ensure that the keypad's address is unique and doesn't match any other keypad on the system, as address conflicts can cause lockups. Also, a shorted green wire can prevent commands from reaching the panel. If multiple devices are on the ECP, connect them one at a time to isolate the problematic wire run.
