dsc 1500/1555 keypad question

[ghstudio]

I have a bad 1550 keypad and will replace it with one from EBAY. I'm almost embarrassed to ask, but do I just press in on the bottom indentation to release the cover to open the old keypad or do I have to do something else?. I obviously don't want to just yank it out of the wall

There should be tabs to release the front section of the keypad from the mounting bracket (back section) - wires are attached so be careful. Once the front is off you need to unscrew the backing plate from the wall.
