This morning I went to unlock my truck this morning, like Ive done a million times, the horn went on. It blared a minute. Open the door, same thing, horn on. Anything I do, more and more horn.

Since this happened at 6am, I disconnected the battery and wait for later.

Any ideas?

Everything worked fine yesterday.

"Update" I tried my backup remote, same thing. Although if I hit the "lock" button the horn will shut off.

 

Got sick of dealing with it, the neighbors were getting upset. Took the truck to the dealer. Hopefully it's covered under my warranty.....

 

The dealer figured out the issue. It was the keyless entry module. The nice thing everything was covered under my extended warranty. Should get it back in the morning.

 

bunch of help we were...

thanks for letting us know and posting the fix

 

If anyone is interested I can post the price for parts on the fix.

 

That is an 02 Double Cab? If so did the RS3200 module have to be replaced?

Looked at your profile- Corolla (spelling?) for your wife is a nice one too.

 

The 02 is no more. I now have a 04. My wife's (corolla) is a blast! Currently I'm looking for a 08 S for myself. One difference, I want a manual.

To your question. Yes it was, an RS3200.
