An engine immobilizer is an electronic device designed to prevent the unauthorized starting of the car engine. This component is attached to the engine Control Unit (ECU) computer. It will ensure the engine doesn’t start without a valid car key. The key usually has an identification chip that your car immobilizer can only identify. But it's not just software updates that you need to keep an eye on. There are also certain firmware updates that can affect your vehicle's operation. For example, it's important to keep your car's electronic control unit (ECU) firmware updated as well.
