So finally got around to wiring my car to the xEM controller.
So because my car doesn’t like to play well with others I had to get a key-fob to use for the project
The goal here was to be able to use a NExT to unlock my car. And to be as low profile as possible. Essentially nothing should be visible either inside or outside the car.
I achieved this by connecting the xEM to my car ground and a unused fuse slot on the fuse box. the signal wire actuates a common automotive relay, The relay closes the circuit to the key-fob’s “Unlock” button which I soldered some wires to.
All is hidden inside my dash in some empty spaces.
And the reader is inside the trim behind the black part of the glass.
it can still read no problem. and nothing is visible form the outside.
Future Goals; Originally I didn’t care about locking the car. Since I thought I’d be able to use the button in the car and then close the door. But if I do this, the drivers door won’t lock. Only way to lock it is to use the keyfob or the mechanical key, sigh.
Anyone have any ideas on how to be able to use the same xEM access controller to “push” both buttons? Ideally it could alterante between pressing one and the other.
some pictures of the installation, and the xEM with the wiring done.
