Most modern vehicles require some kind of transponder key or fob to operate, ensuring security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. They can be costly to replace if they are lost and it is recommended to keep spare keys in the car. You can purchase key fobs to replace them in online stores as well as numerous brick-and-mortar auto shops. But how do you know that the new one you purchased is authentic? Do you know if it has been programmed for a different vehicle or if it could be reprogrammed for yours?

You only have just a few seconds before the car's system reverts the commands and exits programming mode. For this reason, it is important to be quick and not pause between steps. Turn off the engine to avoid this. Switch the key from "on" to "off" to test the system. You should hear a chime indicating that the process was successful. The door locks will go through a cycle.

The key needs to be programmed to match the exact identification code on your vehicle, or else it won't be able to start.
Transponder chips, which are used to stop theft of cars are a standard feature of modern cars. The chip is a microcircuit that transmits a radio frequency signal when the key is put in the ignition. The car then recognizes the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for novice car thefts to wire a vehicle hot and then turn it on.
A circuit board with an induction coil that connects the chip to the key. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This generates a signal that is taken up by the coil, which then transmits it to key's identification number. The key's identification number is then sent back to the car, and the engine starts if the identification number matches.

The chip can be read using a scanner, or a computer equipped with a USB connector.
