Well, I am not sure this will work as the OP has push button start and I think part of the idea was to avoid setting off the alarm on return. I think the idea is simple as long as you do not mind not having the alarm on while away from the vehicle. The other issue with the push button start is the fact that to leave the FOB in the vehicle it must be disabled as there is a safety measure to prevent you from locking it in the car. I think a good fix would be to have an option to disable the beeps when using the button on the rear gate.
