Does anyone know how to disable the horn sound when locking and unlocking the car? It's a 2004 Honda Accord EX and I believe it is an aftermarket alarm that was installed from what I've read. It honks once when locking and twice when unlocking. It is incredibly annoying when you unlock the car at 6 am...I believe I have traced it to a Karr alarm series from that time, but the valet switch seems to be a little different than what others have. Any help would be appreciated!!
