Thanks Suss for the quick reply :)
zhilton, If you are looking to keep it "blonde" simple, Install the DBALL from xpresskit. You will however need their XKLoader to program the unit in whats called RSR mode. This RSR mode allows you to hit lock 3 times on your factory remote within a few seconds and the car will start up for you. Same thing to turn it off.
The down side to just using the DBALL in the RSR mode is that you are limited to the range of the factory keyless. If you are looking for longer range you can add a remote start to the DBALL in another mode or add what is called their range extender kit
