I have a problem with my alarm

I had a power cut last night and it seems to have rendered the system
unresponsive.
I'm getting a power on light but no response from key pad or any other
light.
The power light goes out when I take out the spur fuse so I assume that
the back up battery is dead. I can replace that but what about the non
responsive keypad

First try removing the backup battery AND power entirely for a couple
minutes. It may just be in a strange state.
