I've looked and been unable to find a clear explanation how to remove a front door car with the door locked/closed. But I've also seen reference to garages knowing about the problem getting it sorted with 1 hour labour.

Is this correct; what are the typical costs (plus the cost of a new lock) for a Jag specialist to fix a front door lock that's probably double locked? 1 hour, if correct, is about £100.

Or is there a ridiculously easy trick to getting the card off?
