this is 'cool but stupid'.
Running a relay into the car to a switch thats protected just moves a analog electrical problem somewhere else, it' still just two wires to jump at the end of the day
What you want is what smarter cars have, integration to the ECU. So you put in the wrong key, it does a crypto exchange with the ecu, and the ECU won't crank. Even if you crank it by jumping the solenoid, it won't power the fuel pump, the computer will still say 'I am off' sorry no fuel no timing, nothing.
- okl 3y agoRight, the image shows it connected to the battery pole. Just pop the hood, bridge the contacts. Any proper solution has to be integrated into some essential part that is difficult to access (like the ECU). Maybe they want that thing to talk to the ECU? Otherwise, how is it locking the car?
- calvinmorrison 3y agoa lot of cars have cutoffs switches for all sorts of stuff, like rollover switches, overboost limiters etc... you could tap into any of those to immobilize a car. but you need to tuck that shit up under neath in the dash or wherever the ECU is, and that doesn't solve any issues because it's still just one wire to short out. You need something tucked up underneath you can use wireless transponder so theres nothing obvious preventing it from cranking.
