I'll bear that in mind, if I have to go inside.
So how old is the battery you haven't gone inside to replace?
There's a reset in there by shorting 2 test points - you usually have to do
that after replacing the battery.
Can't hurt to try that, and its a good excuse to put a new battery in
anyway.
Lithium coin cell shelf life is somewhere in the direction of 10yrs, but
mine uses the oddball CR1620, so who knows how long its been hanging on the
display rack.
