The majority of modern vehicles require a transponder key to operate. This is a security feature and protection against theft.

You can find key fobs to replace them in online stores as well as numerous brick-and-mortar auto shops. But how do you know that the one you have bought is authentic? Can you tell whether it has been programmed to work with another vehicle or if it could be reprogrammed to fit your vehicle?
If you're looking to program a new key first, you need to make sure that your car is running. Insert the key you wish to program into the ignition, but do not turn it. There are only a few seconds left before the system will reset all commands and exits the programming mode. For this reason, it is important to move quickly and not be able to wait between steps.

This makes it harder for novice car thefts to connect a vehicle to a hot wire and then turn it on.
The chip and the key are connected via a circuit board that includes an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This creates a signal that gets amplified by the coil which transmits it to the key's identification number. automotive key programming of the key is then sent back to the vehicle, and if it is in line with the engine will start.
