Remote starter makes horn honk
We have a 2006 GT with the remote starter, which is an awesome option. But lately we've found that trying to start it with 1 of our key fobs makes the horn honk (like a panic mode) rather than start the engine. The other fob works just fine. We've duplicated it many times: following the correct procedure (lock -> start) our 1 fob starts the car just fine, and the other one put the car into a horn honking cycle until we push lock again to make it stop. Nothing found in the manual about this, anybody seen this before? Thanks.
