Keys

The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is placed. The car is able to detect the signal, and starts the engine only if the signal matches the original that was programmed in the vehicle. The car will also shut down if the frequency is invalid. This makes it much harder for thieves who are not experienced to connect a vehicle with hot wires and start it.

The key and the chip are connected by a circuit board that includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal that is received by the coil and then transmitted to the key's identification number. The ID number of the key is sent back to the vehicle and if it matches, the engine will begin to run.
