12v Trigger? Newbie here.

Well look at that. I was actually able to pull off part 1 of my project. My RFID keyless entry to my apartment without modifying the door, lock, or striker (I'm not allowed too) is now installed and working beautifully.

I just wanted to say thanks to those who helped me below. I wanted to quit and now that I see progress I am actually ordering another arduino to try more projects.
