What is a Transponder Immobilizer?
A transponder immobilizer is an electronic security system that prevents unauthorized engine starting. The key contains a small chip, called the transponder, which communicates with the immobilizer system in the vehicle. If the transponder’s signal matches the data stored in the vehicle, the engine control unit is enabled.
An example: Imagine you try to start your car with the wrong key. Without the correct transponder, the immobilizer will block the starting process. The engine won’t start, and your vehicle remains protected.

How Does the Transponder Immobilizer Work?
Communication between the key and the vehicle occurs via an electromagnetic field. As soon as the key is inserted into the ignition switch, the immobilizer sends an interrogation signal to the transponder in the key. The transponder responds with a unique code. If this code matches the data stored in the vehicle, the immobilizer is deactivated, and the engine can be started. “The technology of the transponder immobilizer is constantly evolving to stay one step ahead of thieves,” says Dr. Ing. Klaus Müller, an expert in vehicle security systems, in his book “Modern Vehicle Technology”.
