Ah Okay thank you for explaining that! Makes total sense now. This will definitely help me out. I think I'll do the same as you and just start out with the Mega.

I'm sorry I'm honestly confused on what you mean by the Uno or Mega. Sorry still a Noob.

I'm still doing all of my research into everything. I need to hurry up and just buy the arduino, board, and ring and just start messing with everything. That'll honestly be the best way for me to figure it out.

Oh my god!! You have a skyline!! That's amazing!! I'm over here with a s13 240sx.

That'll honestly be really cool to see. Aren't your doors all metal though? Won't the signals not be able to pass through?

That would be pretty cool! I'm honestly just afraid of doing that just in case it happens to malfunction. That way I can just revert back to my key if all else fails.

Thank you very much for your amazing replies. I mean't to to say relays lol not resistors. I was still waking up before work when I typed that. I realized today that my car does actually have plastic door handles so my original idea might actually work. I'm thinking up having the sensor positioned up from underneath the handle so when I go to grab for it, it will unlock the door.

Will do! Are there any websites or links that you would reccomend me going to to read up on programming arduino and NFC along with the resistors? This was I have a decent understanding of what I'm doing.

I really like the Mirror idea. My side mirrors are indeed plastic!

Yeah I'm trying to figure out where it would work. I feel I could put it directly under the handle but that is mostly metal.. Along with my car. What else would I need besides the board I showed and Arduino to get this project going?
