You can purchase key fobs to replace them in online stores as well as many brick-and mortar auto shops. But how can you tell that the new one you purchased is authentic? Can you tell whether the unit has been programmed to work with a different vehicle or if it could be programmed again?

If you want to program an entirely new key the first step is to ensure that your vehicle is on and running. Insert the key that you'd like to reprogramme into your ignition, but do not turn it. You will only have a few seconds before the car's system resets commands and then exits programming mode. Therefore, it is important to move fast and not pause between steps.

The key must be programmed to match the exact identification number on your car, or else it won't start.

Transponder chips, used to stop theft of cars are a standard feature of modern cars. The chip is a microcircuit which transmits a radio frequency signal when the key is inserted in the ignition.

The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it much harder for novice car thieves to hot wire a vehicle and start it.

A circuit board equipped with an induction coil connects the key to the chip. When the key is put in the ignition, a magnetic field is created around the transponder. This generates a signal that is amplified by the coil which transmits it to the key's identification number. The ID number of the key is transmitted back to the vehicle, and if it matches, the engine will begin to run.
