Mine has the Mazda factory Remote Start, very nice feature... can start the vehicle from about 900 feet away, also open the windows, and it has a "car finder" feature which is nice in a crowded parking lot. I also have the keyless smart system. I just leave the credit card size key in my wallet, and do everything else keyless, lock, unlock, starte, etc... can even roll down/up the windows with this system.
