Most modern vehicles require some kind of transponder key or fob to operate, ensuring security and anti-theft protection. The keys must be programmed to your particular car and its systems by a licensed locksmith or dealer. They are costly to replace in the event of loss and you should keep extras handy. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you know that the one you purchased is authentic?

There are only a few seconds left before the system will reset all commands and then exits the programming mode. It is important that you move quickly and don't wait between each step. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a sound that indicates that the process has been successful.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the vehicle. The feature is still vulnerable to a technique dubbed a replay attack.

A reprogrammed key will need to be matched with the specific identification number of your car, or it won't start the engine.

Transponder chips, which are used to protect cars from theft are a standard feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and then starts the engine in case it matches the original one that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much harder for thieves who are not experienced to hot wire a vehicle and then start it.

The chip and the key are connected via a circuit board that includes an induction coil. When the key is placed in the ignition, it creates an electric field 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 number is then transmitted back to the car and the engine will start when the identification number matches.
