Modern cars are geared up with an immobilizer system, an electronic security device that prevents the engine from running unless the appropriate key (or token) exists.
When a programmed key is inserted into the ignition or brought inside a car with push-button start, it sends out a distinct digital "handshake" to the car. If the codes match, the immobilizer is deactivated, and the car begins. Without correct programming, even a key that completely fits the mechanical lock or matches the car's shape will fail to begin the engine.
