First of all, I have been trying to make time to have fun with Arduino projects and now I have something in my mind and want to put it into action. I have some basic knowledge in electronics, also some basic code knowledge but I am eagarly willing to learn and to help also.
I want to make my car central locking device with several operations.
Second of all I want to buy and Arduino. And what I need for this project (I think) is a RF remote, right? So…what RF remote to buy? I found 2 options that, I think, are the easiest ones.
With the first option, I need 4 buttons and all 4 buttons should have just press also press and hold, so press:unlocks the car;press and hold:locks the car.
Can this be done with either of the two options? If so, I will order myself an Arduino and RF remote, also a few relays kit. Then it gets interesting…

Thank you for all the help!
Yes this can be done, but interacting with automotive 12/14V systems can be a little tricky. Although technically the arduino’s can be powered by up to 16v, in practice the boards don’t like that very much. Also, in an automotive system, you don’t just have a battery, there are all kinds of things on the system that affect the power system like the starter and alternator that can damage the board.
I’m not vary familiar with all the different flavors of RF remotes out there, but the ones I’ve seen send a code when pressed and when held down sends that code repeatedly. This means you can do a separate action if your “hear” the same code repeated for x seconds.
