Have you tried entering your user code again to reset the tamper?
You are right to be concerned about SDs suggestion.
That procedure will involve working on a live panel
potentially dangerous,one slip and its game over.Is it worth the risk????.
you mentioned having a service several months ago
still got his number?
Safer to give him a call
Did you change the battery yourself?
my advice is to leave well alone and be safe :)
