I’m a mechanic and I’ve been doing this for years! It’s not all that complicated and you definitely wouldn’t be hitting a button, scanning, opening a door at the same time. Just scan and it’s unlocked. The button is there in case you want to turn off that reader for some time if you don’t like the area you’re in. Once voltage has been sent to the unlock sequence… it’s unlocked. No need to wire it like an RFID door that needs a capacitor or it only opens when it’s activated because that actually could cause some issues.
I find this a slightly difficult to believe although some cigarette lighter are always live, and some head units dont have a remote line, I’ve just never seen a car that hasn’t had some remote wire somewhere. Ether way you could just order a LOC, Line Output Converter, that will tap into existing speaker wires and give you a remote wire, 12v, if you don’t feel like ripping your dash apart to use a voltmeter to find the right wire off the right fuse.
Installing a new ignition switch is entirely specific on your car but still pretty universal wiring so it shouldn’t be too bad. Most of the work will be trying to find the right wiring diagram.
This entire project shouldn’t take longer than an hour nor require too much thought so don’t stress yourself too bad over this. It’s just a few wires. Even just taking it to Car Toys, the 16 year old working in the back could have you taken care of in just a few hours XD.
Best of luck to everyone taking on a project like this! They all differ in some type if way and no one way is best. Do what works best for you
Car mods are easier than they look! After spending probably 4 times more on aftermarket parts than what I bought this car for, I can safely say that this is one of the easiest mods to do with minimal modification. It can easily go back to stock in the matter of minutes if you need to sell the car.
