Keys

Most modern vehicles require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. The keys have to be programmed to your specific vehicle and program its systems by an authorized dealer or locksmith. It is expensive to replace them if they are lost, so it's better to have spares available. You can locate key fobs to replace them in online stores and numerous brick-and-mortar auto shops.

You will only have just a few seconds before the car's system resets commands and leaves programming mode. It is crucial to move quickly and don't be patient between each step. To prevent this from happening, turn off the engine. Switch the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a sound that indicates that the process has been successful.

The chip and the key are connected by a circuit board that includes an induction coil. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This produces a signal which gets absorbed by the coil, which transmits it to the key's identification number. The key's identification number is then transmitted back to the car, and the engine starts when the identification number is in line with.
