CaRFID - Custom Ignition Switch Replacement (Open Source)

An unintended but welcome side effect of the screen, it’s really, really easy to notice now if I accidentally leave it on. I had intentionally made it so there were no status LEDs on in the idle state (not running & deauthenticated) in order to reduce power draw in the event of me leaving it on.

This was great as I could accidentally leave the board on for days without ill effect, but after leaving it on once or twice, I got worried, given that I sometimes don’t drive for over a week when I’m at college.

With the screen on, I can’t really leave the car without noticing that I left it the system on, with it saying “Scan implant:”.

Shouldn’t have any issues anymore. One thing I would definitely recommend to anyone doing this, or any other ignition replacement, is to go to your local hardware store and have a spare door key made. I needed to do that earlier for the ignition lock bypass, but I went back today and had another made for another $4. This is so that if I leave anything on (worst case scenario), and drain my battery completely, I can still get inside my car to pop the hood and jump the vehicle. I have a jump pack in my trunk, so it’s no biggie if it happens, and having the spare key gives me immense peace of mind for only $4.
