I have the port installed alarm, and it work seamlessly with the key fob. I don't have to push any extra buttons, all I have to do is grab the door handle, and wait for the beep then open the door.

Someone mentioned the TCH does not use motion detectors on the alarm, I have not tested this, but if it does not, I am a little PO'd about it. The only reason I wanted the alarm is to know when the car has been broken into if I am around it. I have had my truck broken into twice when I was within sight of the truck (both times at a strip shopping center near a highway).
