Most modern vehicles require some kind of transponder key or fob in order to operate, providing security and protection against theft. The keys have to be programmed to your specific vehicle and its systems by a certified dealer or locksmith. It's expensive to replace them if they become lost, so it's better to have spares in your possession. You can locate replacement key fobs in online stores and many brick and mortar auto shops. How can you be sure that the one you purchased is authentic? Can you tell whether it has been programmed for another car or if it can be reprogrammed for yours?

If you're looking to program an entirely new key first, you need to ensure that your vehicle is operating. Insert the key you want to reprogramme into the ignition, but don't turn it. You have only a few seconds before the system resets all commands and leaves the programming mode. Therefore, it is crucial to move fast and not pause between steps. Stop the engine to avoid this.

This makes it much harder for thieves who are not experienced to connect a vehicle with hot wires and then start it.

The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This produces a signal which is amplified by the coil which transmits it to the key's identification number. The key's ID number is sent back to the vehicle, and if it matches the engine will begin to run.

There are a variety of ways to program a transponder, but all of them require a special tool. You can purchase these tools online or at most automotive locksmiths. They're not cheap, but they're crucial for programming the chip to your vehicle.
