I have an xEM implant and an access controller and I have been looking for a general diagram to connect it to my cars door lock. If anyone knows any website too look at to find more information that would be greatly appreciated.
The easiest thing to do is hack a spare key fob. Connect a relay’s coil pins to ground and the white output wire of the access controller, then connect the NO (normally open) pins on the relay to both sides of the unlock button leads on the keyfob PCB. Pass your implant over the antenna, relay closes, connects the button leads as if you pressed the unlock button on the keyfob. Works great. Also disarms the alarm if you have one integrated.
