A frequently used way to steal cars with keyless entry systems is to find out where the key is, use a transponder to forward that signal to another transponder, which is in the vicinity of the car.
This transponder chain will then make it look like the key is right outside the car, so you can unlock the door. In the next moment, you use it again to start the car.

To mitigate this, when the key is stored in the house, new cars frequently are equipped with keys that turn off their transponder, if they haven't moved for a while.
This doesn't help when the perpretator simply walks beside you, after you left the car, though.
