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

There are only a few seconds before the system will reset all commands and then exits the programming mode. It is important that you move quickly and don't delay between each step. Turn off the engine to avoid this. You can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle, and you will hear a chime to indicate that the procedure was successful.
Certain newer vehicles have rolling key system, which keeps thieves from using a stolen car's key to open it. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and duplicate the signal generated by the key fob of the vehicle to unlock the car.

Car keys with transponder chips require a specific reprogramming to work. Any hardware store can give you an entirely new car key, however the real challenge lies in integrating it with your vehicle. The key must be programmed to match the exact identification code on your car, or else it will not start.
Transponder chips are a standard feature of modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is inserted into the ignition. The car then detects the signal and then starts the engine if it is in line with the original signal that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it harder for thieves with no experience to wire a vehicle hot and then turn it on.
The key and the chip are connected via the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This generates a signal, which is absorbed by the coil and then transmitted to the key identification number. The ID number of the key is transmitted back to the vehicle, and if it matches, the engine will begin to run.
