fob/key/transponder/immobiliser are all separate systems ( some have them all like in the UK ) but in the states im told they dont have the immobilizer? if not that would simplify things,
the alarm is turned on by the fob as it locks the doors and all you need to do is unlock it with the key to turn it off should the fob become damaged,
in the UK and most other countries the key has a chip in it so only that key can start the car so "no immobilizer means no chip" and chaser is correct
