Keys

Transponder chips are a typical feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted in the ignition. The car detects the signal and starts the engine only if the signal matches the one programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it harder for thieves with no experience to connect a vehicle to a hot wire and then start it.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal, which is received by the coil and sent to the key’s identification number. The key’s ID number is transmitted back to the vehicle, and if it matches, the engine will start.
