if he did use the express kit . . something is funky.
I've installed a few of the newer bypass kits and they are great for the new subies. I've done a wrx and a few foresters.
The module connects to the CAN wires in the vehicle and it gives you the ability to control the door locks, factory alarm features, and bypass the immobilizer without loosing a key.
tying into the factory alarm system was not an option in the previous model years (02-07)
