[Shotimes] Help Locked out with a dead battery

[ANTHONY J Clerkin]

Allright, once again I prove that I am an idiot.  My SHO is for sale, so all 
the keys are on the same ring with the remote.

It's been cold here in Illinoise, so the battery died, with all the keys and 
the remote inside.

Any ideas?  Can I charge the battery from underneath?

Thanks,
Dumb in da midwest
