Optima Compact G3 Tamper Lock

[timc73]

I have an Optima Compact G3. It was in the house already when we moved in back in 2006. It has worked fine, had to replace the battery about 10 years ago and it worked fine afterwards.

A couple of months ago the tamper light came on and then none of the buttons on the keypad work. I suspected that it might be the battery again so have replaced it (only just got round to it) with a new one. The old battery was indeed faulty when I tested it with a volt meter. The new battery is reading 12v fine.

However, it has not fixed the issue, the tamper light is still on and the keypad is not responsive. Looking at the manual it describes this as a lock out, but it does not offer much in the way of help to fix it.

Any advice? - is there some sort of reset I can try? I have been round to all the sensors and they all respond with movement as normal. The tamper spring sensor does not seem to make any difference if I push on it or not (when the cover is off).

Thanks
Tim
