Keys

Nearly all modern vehicles require a transponder key or fob in order to operate, providing security and anti-theft protection.

The key must be programmed to match the exact identification number on your car, otherwise it won't be able to start.

Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then recognizes the signal and then starts the engine in case it matches the original signal that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.

A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is taken up by the coil before being sent to the key identification number. The ID number of the key is then sent back to the vehicle and if it matches, the engine will start.
