Had a rather interesting experience about 300km from home yesterday.
The Jaguar has a start button which functions when the key is in or very near the car. Once started I believe it will keep going even when the key is out of range.
BMW's are like that. My son had that experience, his wife had opened their car he then got in and drove her to work where she got out, he drove on when he finally stopped at his destination he could not find the fob to lock the car. His wife had put it in her handbag, result one grumpy son as he couldn't then restart the car and he had to get a lift to go and collect the fob.
