Keys
Modern cars require a transponder key to operate. This provides security and anti-theft protection. The keys must be programmed to your particular vehicle and its features by a certified locksmith or dealer. It is expensive to replace them if they are lost, so it's better to keep extras on hand. You can find replacement key fobs in online stores as well as many brick and mortar auto shops. How can you be sure that the one you bought is genuine? Are you able to tell if it has been programmed for another car or if it is able to be reprogrammed for yours?
If you're looking to program a new key first, you need to make sure that your car is operating. Insert the key you wish to reprogramme into the ignition, but don't turn it. There are only a couple of seconds before the car's system reverts the commands and then exits programming mode. This is why it is crucial to move quickly and not wait 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 will hear a chime signalling that the process has been successful.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique dubbed replay attack, which allows thieves to record the signal received from the key fob on the vehicle and reproduce it later to open the car. To prevent this, manufacturers have introduced an additional security feature known as the CAN bus protocol to thwart attacks on hacking.

Transponder chips
Car keys with transponder chips require a special reprogramming to work. Any hardware store can make you a new car key however the real challenge lies in integrating it with your vehicle. The key must be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips are a typical feature of modern cars and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is put into the ignition. The car then detects the signal and begins the engine in case it matches the original signal that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.
The chip and the key are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This generates a signal, which is received by the coil and sent to the key's identification. The key's ID number is transmitted back to the vehicle and if it matches, the engine will start.

In this scenario you'll need to make sure that the key is not damaged or the transponder has been altered in any way. The chip can be read using a scanner, or a computer equipped with an USB connector.

If you're a beginner, it's best to seek out the help of an auto locksmith. Also, avoid buying second-hand keys, since they are likely already programmed and won't work with your car.
