All I can say is don't get caught out in a place with no phone signal. You might be able to get into the car, but once the car wont 'start' without the key card, it can still be pretty frustrating when you have it but tucked away somewhere, or its still inside your house. Not all charge sites have good mobile signal, nor do underground car parks. And there is something about when I wash the car that can occasionally can lock me out too.
