The majority of modern vehicles require a transponder key to operate. This is a security feature and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. It's expensive to replace them if they are lost, so it's a good idea to have spares in your possession. You can locate key fobs that can be replaced in online stores as well as numerous brick-and-mortar auto shops. But how can you tell that the one you purchased is genuine?

To program a new car key, you must first verify that your vehicle is operating. Insert the key that you wish to reprogramme into the ignition, but do not turn it. You will only have a few seconds before the car's system resets commands and exits programming mode. For this reason, it is important to move quickly and not wait between steps. Stop the engine to prevent this. You can test the car's system by turning the key to the "on" position and back to the "off" position. The door locks should cycle and you will hear a sound that indicates that the process was successful.

Transponder chips, used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit which emits a radio frequency signal when the key is put in the ignition. The car then recognizes the signal and begins the engine if it is in line with the original signal that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it difficult for thieves with no experience to hot-wire a vehicle and then turn it on.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition it creates a magnetic field created around the transponder. This creates a signal which is received by the coil and then transmitted to the key's identification number. The key's identification code is transmitted back to the car, and the engine starts when the identification number matches.
