Keys

Most modern cars require a transponder key in order to operate. This provides security and protection against theft.

Transponder chips are a typical feature of modern cars and are designed to prevent car theft. The chip is a microcircuit that emits a radio frequency signal when the key is put in the ignition. The car is able to detect the signal, and starts the engine only if the signal matches the original that was programmed into the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.

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