Odd, I had the same problem. Only, the CR2032 I had was kind of old (it measured ok with no load, but under load, it totally sucked.)

1) take the battery out, measure the voltage with a 1k load (ermm. get a cheap DMM from harbor freight or something, they have a cool battery test feature that is very useful. It's also a really useful tool that can save your butt sometimes...)
-- if you don't want to do this, buy another known good battery.--
2) Clean the battery and contacts.
3) reinstall the battery (don't put the cover back on just yet.)
4) push the lock button.
5) does the led on the upper right flash? if not, take the battery out and repeat #3.

my theory: this happened to me, I replaced the battery with a 'known good' source. I'm not sure whether the CPU inside the FOB actually reset properly or decided to challenge me.. It took several power cycles to get it back up. Just make sure to press the button and look for the LED to blink before wrapping it back up..

At this time it might also be a good idea to clean the o ring area so that the fob remains waterproof.

I'm replacing the one FOB battery at 4 years and 4 months. (November 2003-March 2008) I think that's pretty good. Our 2nd (lesser used) FOB CR2032 battery is still going.
