XnT unlock your car/do whatever you want with it
So I didn't know of a better way to show people this so I am just making a new post. I have seen people that use their tag to unlock a car, or unlock their house and I wanted to do the same thing. but I didn't know how the hell they were doing it with like custom kits and things. So when looking up how to do it I decided that it all sucks and I wanted to do it my self. So I took my car key fob apart and took the battery and buttons off of it. I then wired the parts for the battery into an arduino with some firmware on it (will put link at the bottom) and a NFC reader from adafruit. I then soldered the button for unlock to be always pushed and I was done. I just needed power and I can now unlock my car by scanning my hand. But the cool thing about this is the firmware I wanted to make something that would scan your hand and do *blank* whatever you wanted! so now we all have firmware that we can put in with existing project that can act as a button press or more a motor, or something like that.
So please check it out and feel free to make your own car unlock system or whatever you want. If you want I would also be willing to make some systems for people so you can look cool in front of your friends.

My car had some security feature where the unlock button couldn’t be pressed from inside a locked car or I would have wired it there instead of using battery operated fob.
I was planning on trying to directly wire into the locking system and run the reader up to my door where i would normally place my hand to unlock it.
My question is why are you using a keyfob? Is this just because you do not want to/ know how to or where to wire into the truck as i said i will be doing?

Yea I am kinda paranoid about a bike I have been saving up for getting stolen....
I may also need to be creative if that proves to complex. Good thing is I only have two doors to unlock ;)
Wiring into the lock button would eliminate the need for a fob to be tied in and would make it so you don't need to trace wires back. Bare in mind this is just to unlock the car and not start it.
I found out I actually just had some corrosion on my plug so the button function is fine. My current rt would be simply identifying the prong for unlock and then just crimping the wire into that plug.
I'll be doing some similar automotive bio-integration mods before too long.
This was the first time I had to actually do anything to this truck. Your saving me time on the looking through the Google for wiring diagrams thank you much @posthumanist.
I'll consult with my electrical diagnostician once I know which diagram is correct for your vehicle.
What mods will you being doing with you vehicle to integrate with you?
This is a grounded circuit, meaning in order to actuate the mechanical lock you will apply a ground to the wire NOT power.
I'm trying to think of a way to use my remote start right now but I haven't been able to think of anything I really like. I'm toying with the idea of implanting a remote start with a Reed switch and using a magnet to trigger it. (I would also have to have a magnet too).
The remote start I think could be rigged to be keyless also but I haven't really looked into that yet and the obvious problem would be a powers ounce for the remote.
The ultimate goal for me would be to install an RFID reader in the driver door handle that would unlock the door, disable the alarm, and start the engine. I would of course need to bypass the steering wheel lock mechanism in the column and wire a dummy load so the remote start thinks the vehicle has a key in the ignition so I can just hop in and go.
Now, I would need To do that with one chip implanted in my hand and on the other hand, a chip that would send a signal to lock the doors and arm the security system as I exit.
