Keys
Most modern cars require a transponder keys to operate. This is a security feature and anti-theft protection.

How do you ensure that the one you have bought is authentic? Can you tell whether it has been programmed for another car or if it is able to be reprogrammed to fit your vehicle?
To program a new car key, first make sure that your vehicle is operating. Insert the key you wish to reprogram into the ignition, but do not turn it. There are just a few minutes before the system resets all commands and leaves the programming mode. It is crucial to be quick and don't delay between each step.

The door locks should be able to cycle, and you'll hear a sound that indicates that the procedure was successful.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to open the car. The feature is still vulnerable to a technique called a replay attack.

To combat this, manufacturers introduced a security feature known as the CAN bus protocols to stop hacking.

Transponder chips
Car keys with transponder chips require a special reprogramming to function.

A key that has been reprogrammed will need to match the exact identification number of your vehicle or else it won't be able to start the engine.
Transponder chips, used to protect cars from theft are a standard feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is inserted in the ignition. The car then recognizes the signal and then starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incompatible frequency. This makes it more difficult for thieves with no experience to wire a vehicle hot and then start it.
The key and the chip are connected via a circuit board that includes an induction coil. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This creates a signal which is received by the coil and sent to the key's identification number. The key's identification code is sent back to the car and the engine will start if the identification number matches.
