Keys

The majority of modern vehicles require a transponder key to operate. This gives security and protection against theft.

Transponder chips, used to protect cars from theft, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is placed into the ignition. The car is able to detect the signal and begins the engine only if it matches the original that was programmed in the vehicle. The car will also shut down if the frequency is not valid. This makes it difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.

A circuit board that has an induction coil that connects the key to the chip. When the key is put in the ignition the magnetic field is generated around the transponder. This creates a signal that is taken up by the coil, which transmits it to the key's identification number. The key's ID number is then sent back to the vehicle and if it is in line with the engine will begin to run.
