I recently bought a 2003 Altima 3.5 SE. The dealership didn't have the remotes but gave 2 new ones. Service was closed. When I got home I followed instrictions found online and successfully programmed the remotes to the car.
Problem: The option to silence the horn with locking and unlock doesn't work. If I hold down the lock and unlock buttons, after a few seconds the parking lights blink; but it doesn't stop the honking.
I doubt that the dealer will be helpful..... any suggestions?
