Hi Steve & Nicola,
sounds to me like your keypads are locked out , the cause of this is normally the battery is in need of changing.
To get it up and running again simply disconnect the mains power from the main panel by removing the fuse from the spur unit, then remove the front & disconnect the battery.
Then reconnect, but leave the battery disconnected.
The panel should come back to life again.
Enter your code to turn off, if your code doesn't work try 0123, replace panel front & press reset.
You can buy a battery from any electrical wholesalers for £10 approx.
Hope this helps
Regards
