Lately I've been noticing (at least from where I park at home) that after the car has been locked via the remote key fob, my '03 sedan horns off at random times. The car stays locked the entire time but the hazard lights and the horn go off once in a while. This is strange behavior as my key fob sits untouched inside the home, and no one is near my car when it's locked.

Has this ever happened to anyone's G35? What can I do to fix this problem? I live in a condo complex, and I do not want to disturb my neighbors with this unpredictable behavior.

Oh, I should point out that I actually have 2 key fobs in my hands: one is working, and the other one isn't (even though I changed the battery which didn't help at all).

 

have you tried taking the battery off the one thats not working??

 

have u had any stereo equipment installed? i had this happen in my old car after some re-wiring and it had something to do with the relays and such. PITA to sort out!

 

I removed the battery from the non-operating key fob for now. However, I did have the CD changer unit replaced under warranty a while ago at the dealership, so that may be a possibility. We'll see what happens after this weekend, and if the same problem remains, I will go back to the dealership and inquire about the problem.
