This interaction is assisted in by a small transponder chip embedded in the head of the key or within the electronic circuitry of a keyless entry fob.

When a chauffeur attempts to begin the automobile, the Engine Control Unit (ECU) sends a request for a code. The transponder sends its unique identification back to the ECU. If the codes match, the immobilizer is shut off, and the car begins. If the codes do not match, or if the signal is absent, the vehicle remains fixed. Reprogramming is the process of teaching the automobile's ECU to recognize a brand-new transponder chip or resetting the connection between an existing key and the Car Key Programming Cost.
Key Types and Their Programming Needs
