Hey guys, I hope everyone’s weekend was as good as mine.
On Saturday I wired an xEM access controller into my car’s locks, a 2013 Hyundai Veloster. I ran the antenna into my side mirror since the doors are metal, and it seemed like the most ergonomic approach. I wish I had taken some pictures to give you guys a proper write up, but when I get the itch to do a project I don’t think of such things.
It was a fairly simple but time consuming project. I removed the mirror and door from the car entirely. I used silicone wire to extend the antenna wires, just to have some extra wiggle when folding the mirrors. I had to run a [fused] power wire through the factory loom/weatherproofing into the door to power the xEM. I was originally going to tap into power in the door, but it turns out that all power to my door is lost with the courtesy timer for the interior lights and such. The lock switches themselves ground a relay in the fusebox which actuates the locks. This was a benefit as it’s very low current draw, and I was able to simply jumper the unlock wiring straight through the COM and NO on the xEM. No need to add an automotive relay to the circuit.
All in all this was about a 6 hour project, mostly because I’m very compulsive with wiring. It turned out perfectly clean and works great.
I posted this to an automotive group and let me tell you, they did not take it well. Mark of the beast, stupid, waste of time, “it’s gonna be so easy to break into your car now” etc. One guy even called me a dweeb 
I want to thank all of you for existing. These sort of things bring me a lot of joy, and none of it would be possible without all of you keeping this niche interest alive.
