Ie do a second poll of the key This has been a solved problem for some time in luxury/expensive vehicles. Vehicle tracking systems detect if the car is moved without the tracking card in it and silently inform their control centre of the fact, along with vehicle’s location. Control centre then calls owner and verifies if it’s them. Doing it this way has the advantage that if the driver is being threatened (carjacking for example), it doesn’t put them at further risk.
