Dangit! I knew I forgot something.

As for why a low battery would cause a problem, just guessing, but I'm thinking the componentry that received the signal from the remote isn't getting the right signal, or low voltage in general just causes issues.

If my alarm had been off, then I might have been able to start it and charge it back up. Or it would have just not started and I would have gone right to the battery as a source. As you mentioned, you leave yours unlocked, so when it's dead, the lock/unlock/alarm never enters into it.

I'm just really hoping a low battery is really the culprit and not deeper electrical issues. The fact that the fuse blew on Saturday before the key fob/alarm issue has me worried....
