DSC LCD5500Z repair help

I have a DSC Classic PC 1555 with 2 DSC LCD5500Z wired keypads. One of the keypads is not working and the red light is on the alarm. The buttons don’t “beep” and the display has stopped as far as keeping up with date and time. The other keypad works perfectly well. Any ideas on how to troubleshoot the broken keypad? Thanks!

Power the system down, and swap the two keypads. If the issue follows the keypad, then you have a failed keypad, if the issue follows the location, you may have a bad cable between the alarm control and the keypad location.
