Key fob Lights Up, Doesn't Work
My key fob lights up with button presses, and the key works fine to lock and unlock the car, deactivating and reactivating the alarm system, but nothing happens with button presses other than the red light illuminating.
This happened after the negative cable came loose recently and the car wouldn't start, necessitating tapping the cable back down. I've had problems with these stinking cables not tightening down on the posts, so I've installed post shims. The positive cable post shim helps it be tight, but the negative side is too tight with the shim and won't go down all the way. Still working on a good fit there so it doesn't keep getting partially dislodged after a bump. It's never fully off, just about 2/3rds of the way off, so it drives fine, just won't restart if that happens until you pop the hood and tap it back down.
Anyway, I've tried the trick of turning it to the right, holding the lock button until the right button flashes fast, then releasing the button and turning it to the left and doing the same with the unlock button. Still doesn't do anything.
Any ideas or familiarity with this problem?

Only say it because mine is going, and the little light on the fob still lights.

I changed the battery out and while the red light seems brighter now on the fob, that didn't fix it. At least I have a new battery! Good thought though.
I performed a reset of the electrical by disconnecting the battery, connecting the negative and positive connections to each other with some soldering wire (don't know if it even did anything), and waited a couple minutes and reconnected the battery cables to the battery.
The fob works!
Seems like maybe the program that runs the fob froze up or something and resetting it did the trick.
