Keyless entry and start system

Does anyone know if you can get a keyless entry and keyless start package to add to the coupe? I've had a look on google but all I can find is a remote central locking and I'm after the one were the system can tell that your a few feet form the car and open, then a start button to get you going (just like the 370z).

Cheers,
Chris.

This...
there are more, and cheaper also...
some chinese solution

Thanks. I'll look into this further.

I like this but with the push start would you still need the KEY to unlock the wheel and turn the car to the acc? if anybody knows

hi, i've looked a bit in to this for my car but gonna practice on my other halfs car lol. you can just remove the steering lock pin from the steering coloum. as for turning to acc, no the passive signal from the cardkey does that, pressing the brake pedal, activates the on switch and holding the start button starts the car, all in sequence..... i think lol. just need to figure out how to remove my alarm an immobiliser
