Inertia switches are only found on Ford vehicles. Since the air bag deployed, that is your issue. Once an airbag deploys you won't be able to start the car due to safety reasons, it's disables the fuel system and battery to prevent a fire. The airbag needs to be replaced and the systems needs to be cleared and reprogramed with professional software Have the LR towed to a garage or auto body shop to help you. From now one, when working on an electrical part of the vehicle, you need to disconnect the negative battery cable from the battery to prevent shorts and airbag deployment.
