You can find key fobs that can be replaced in online stores as well as many brick-and mortar auto shops. How can you ensure that the key you purchased is authentic? Are you able to tell if the unit has been programmed to work with a different vehicle or if it could be programmed again?

To program a new car key, you must first verify that your vehicle is operating. Insert the key you'd like to reprogramme into the ignition, but don't turn it. There are only a few seconds left before the system resets all commands and then exits the programming mode. It is crucial to move quickly and do not be patient between each step. Turn off the engine to stop this. Turn 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 keep thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique dubbed a replay attack that allows thieves to record the signal received from the key fob on the vehicle and then replicate it to open the car. To prevent this, manufacturers introduced the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

This makes it more difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.

The key and the chip are connected via a circuit board that includes an induction coil. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is taken up by the coil and sent to the key identification number. The key's identification number is returned to the car and the engine is started when the identification number matches.
