A transponder key includes a code transmitter that when inserted into a vehicle, sends a unique alpha-numeric code to the ignition of the automobile to turn on its engine. Whether with programming or reprogramming transponder key revolve around the model or make of a car.

Anytime you place your keys in the ignition switch cylinder and try to turn it, the transponder feature in the car sends an electric vibration to the fire telling the core to take a pulse back. If the vehicle’s computer gets the correct pulse value, it incapacitates the immobilizer thus allowing the engine to start.

Programming a transponder auto key is when you familiarize the vehicle’s computer to the transponder chip in the key. This first introduction may need special tools and machines to kick start things (known as On-Board Programming).

On Board Programming (OBP) is a means of programming transponder keys without the use of any expensive programming tools or equipment. Some vehicles are designed with an onboard programming feature only to include an additional key when there are one or two keys already functional, while other manufacturers allow the transponder system on board to be programmed even for the first master key.
