My neighbour has one of these and "lost" the key somewhere in the car. The vehicle has keyless go,so no problem using the car,but unable to lock it up as the system still thinks the key is in the cabin. Only way to lock it is with the second key emergency metal blade into the door lock. Eventually found the key,it had fallen down the centre console ,by the handbrake. This has a solid plastic trim, rather than a more tight fitting gaiter, which leaves a large gap. Even found a £10 note down there!
