The majority of modern vehicles require a transponder key to operate. This provides security and protection against theft. The keys must be programmed to your specific vehicle and its features by a certified locksmith or dealer. They are costly to replace in the event of loss therefore, you should keep extras handy.

If you want to program an entirely new key, the first step is to ensure that your vehicle is operating. Insert the key you want to program into the ignition without turning it. You will only have just a few seconds before the car's system resets the commands and leaves programming mode. It is important that you move quickly and don't be patient between each step.

Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the car.

To prevent this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded by an easy program. You should only try this process if your experience is with electronics.

Transponder chips
Car keys that feature transponder chips need special reprogramming to work. Any hardware store can make you a new car key, however the real challenge lies in implementing it to your car. A reprogrammed key will need to be compatible with the specific identification number of your car, or it won't start the engine.
Transponder chips are a standard feature in modern cars and are designed to prevent car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is put in the ignition. The car then detects the signal and then starts the engine if it matches the original frequency that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it much harder for thieves who are not experienced to connect a vehicle with hot wires and then start it.
The key and the chip are connected via a circuit board that includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This creates a signal that gets absorbed by the coil, which transmits it to the key's identification number. The ID number of the key is sent back to the vehicle, and if it is in line with the engine will start.

In this instance, you must ensure that the key has not been damaged or that the transponder isn't altered in any way. To do this, you'll need scanners or a computer with an USB port to scan the chip and determine its identity.
The process of reprogramming an transponder's key is easy, but it will require specialized software and a scan tool. If you're just beginning, it's best to seek help from an auto locksmith. Avoid buying used keys as they could already be programmed and will not work with your car.
