Keys

Nearly all modern vehicles require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. They are expensive to replace in the event of loss and it is recommended to keep spare keys in the car. You can also find replacement keys fobs on various websites and in many brick-and-mortar auto shops. But how can you tell that the key fob you bought is authentic? Are you able to tell whether it was programmed for another car or if it is able to be programmed to work with your car?

To program a new car keys, first make sure that your vehicle is operating. Insert the key you want to reprogram into the ignition, but do not turn it. You will only have just a few seconds before the car's system resets commands and leaves programming mode. It is crucial to move quickly and don't wait between each step.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to open the car.

The car will also shut down if a frequency is not valid. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then start it.

A circuit board equipped with an induction coil connects the key to the chip. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This creates a signal which is taken up by the coil and sent to the key's identification number. The key's ID number is transmitted back to the vehicle and if it is in line with the engine will start.
