My wife's 2003 Tahoe battery went dead last week (left the GPS plugged in).

Recharged the battery and the car starts and runs good but several odd things are now happening:

1. Unable to program the remote door keys.
2. Unable to lock or unlock the doors with the door switch on the passenger door.
3. The radio turns off immediately when the ignition is turned off. Before it didn't turn off until a door was opened.

#1 and #2 is a "Gotta Fix" (Mama ain't happy)

#3 is just another symptom of the problem

Checked with a couple of local mechanics and emailed a local Chevy dealer but so far nobody has any idea and the only response from the Chevy dealer is, "We received your email."

Anybody got any ideas?

Not an auto mechanic, but when the battery in my F150 was ready to be replaced the electrical systems in the truck started doing all sorts of weird things. The truck started and ran fine, but the radio, door locks, windows and other stuff were really flaky.

Maybe it's time for a new battery?

This happened to me with my 2005 Yukon (same vehicle) and I was told to disconnect the battery for a full day or two and let the car sit with no electrical current at all. Surprisingly it worked, something to do with all of the electronics having to be "drained and rebooted".
Don't ask me to explain it because I can't, I just know it worked for me.
Good luck..

I had the same issue with my Trailblazer. Just disconnected the battery cables for a few minutes and everything went back to normal.

Do this above or you have to get it plugged into a dealer computer to get the codes cleared.

Disconnected the battery this afternoon and since the wife doesn't need to use her car until Monday, we'll give it the full two days to rest up and get rid of its bad hair.
 
Methinks, if you have not already, you should have the battery checked for free at Auto Zone. Recharging does not cut it. Resetting the codes by disconnecting the battery is the right choice, however. Everyone is on track.
 
Hooked up the battery this morning and everything is back to normal.
Mama (and I) both say, "Thank you, Thank you, Thank you" to everyone who answered my post.

My next post will probably be about my personal 83 year old battery and how to rejuvenate it. :biggrin:

Whatever you do, don't try the disconnect trick.
