remote problem

If the remote doesn't work, and also the key LED light doesn't light... I presume it just means the battery needs replacing?

This just happened to me so I'll change the battery this weekend. The weird thing, though, is that it was an instant stop, not a gradual loss like a battery running out. The remote worked great yesterday, and I think the LED light was just fine. Lets see...

If a key's battery is flat dead (not even the least bit of charge in it) does the key have to be reprogrammed?

If the answer is yes, and no barcoded tag is available for that key, is it rendered worthless?
