Almost all modern cars require a transponder key or fob to operate, providing security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and the specific model. It's costly to replace them if they are lost, so it's best to have spares in your possession. You will also find replacement key fobs in various online stores and in many brick-and-mortar auto shops. But how do you know that the new one you have bought is authentic? Can you tell whether it has been programmed for a different vehicle or if it could be reprogrammed for yours?

To program a new car key first make sure that your vehicle is running. Insert the key that you want to reprogramme into your ignition, but do not turn it. There are just a few minutes before the system resets all commands and then exits the programming mode. Therefore, it is important to be quick and not pause between steps.

This makes it difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.

The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field around the transponder. This creates a signal which is received by the coil before being sent to the key identification number. The key's identification number is transmitted back to the car keys programmed and the engine is started when the identification number is in line with.
