Keys
The majority of modern vehicles require a transponder key in order to operate. This is a security feature and anti-theft protection.

Transponder chips
Car keys with transponder chips need special reprogramming to work. While any hardware store can cut keys for you, the biggest challenge is making it function to work with the specific car you own. The key must be programmed to match the exact identification code on your vehicle, or else it won't start.
Transponder chips, which are used to protect cars from theft are a standard feature of modern cars. The chip is a microcircuit which transmits a radio frequency signal when the key is put into the ignition. The car then scans for the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it much more difficult for car thieves with no experience to wire a vehicle and then start it.
The key and the chip are connected by the circuit board which includes an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This creates a signal which is taken up by the coil and sent to the key's identification. The key's identification number is then transmitted back to the car and the engine is started when the identification number matches.
