Keys
Most modern vehicles require some kind of transponder fob or transponder keys to work, which provides security and anti-theft protection.

You can find key fobs that can be replaced in online stores as well as many brick and mortar auto shops. But how do you know that the new one you purchased is genuine? Can you tell whether the unit is programmed to work with a different vehicle or if it could be programmed differently?
To program a new car keys, you must first ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. There are only a few seconds before the car's system resets commands and then exits programming mode. Therefore, it is essential to move fast and not pause between steps. To prevent this from happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a chime signalling that the process was successful.
Certain newer vehicles have rolling key technology that stops thieves from using a stolen vehicle's key to start it. This technology is still vulnerable to a method known as replay attack, which allows thieves to record the signal from the vehicle's key fob, then reproduce it to open the car. To stop this, manufacturers have added a security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an ordinary program. These kinds of cars require programming by a professional, and you should only attempt this procedure with someone who has experience with electronics.

Transponder chips
Car keys with transponder chips require special reprogramming in order to work. Any hardware store can give you a new car key but the real challenge lies in integrating it with your vehicle. The key needs to be programmed to match the exact identification number on your car, or else it will not start.
Transponder chips, which are used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted into the ignition. The car then recognizes the signal and begins the engine if it is in line with the original signal that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much more difficult for thieves who are not experienced to hot wire a vehicle and then start it.
A circuit board that has an induction coil connects the chip to the key. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal which is received by the coil before being sent to the key identification number. The key's identification code is transmitted back to the car, and the engine starts if the identification number matches.
