I came back from a tune-up last night, and this morning my car alarm keeps going off. But there is nothing to turn it on. The alarm is stock, and there's nothing going on. I'm just sitting right beside it and then it goes off. What's worse is the ways to stop the alarm (release trunk, key in front door) isn't working. My keyless entry battery went out about a couple of days ago so I can't use that. It just won't stop!!!!!! I just have it idling outside so nothing happens. Another thing... I tried to lock the doors and the unlock automatically the next second. What is this???? PLEASE HELP! I don't know how long my car can idle.

 

i can't help with the diagnosis but perhaps you could 1) disconnect the horn (or pull the fuse), 2) disconnect the battery, 3) reset the ECU.
I hope this helps,
Cheers,
Matt

 

you can't lock the car w/ the keys in the ignition... so that's why they automatically reopen after pushing the lock... the alarm might be going off because of the remote being faulty, try taking the remote battery out of the remote and using the key to open everything...

Worked. Thanks!!!

 

glad to hear it... what did you do exactly to fix it?

 

It was the remote that was going haywire... Thank goodness for the .org!!!!
