It allows thieves to record and reproduce the signal from the car key fob to unlock the car. To combat this, manufacturers have added a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.

Transponder chips

Car keys that feature transponder chips require special programming to function. Any hardware store can give you an entirely new car key, however the real challenge lies in implementing it to your vehicle. A key that has been reprogrammed will need to be matched with the exact identification number of your car or else it won't be able to start the engine.

Transponder chips are a typical feature in modern cars and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is placed into the ignition. The car then scans for the signal and begins the engine if it matches the original one that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it more difficult for car thieves with no experience to wire a vehicle and start it.

The chip and the key are connected by an electronic circuit board that contains an induction coil. When the key is put in the ignition the magnetic field is generated around the transponder. This creates a signal that is amplified by the coil which then transmits it to 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.
