Keys
Most modern vehicles require some kind of transponder fob or transponder keys to work, which provides security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to work with the car's systems and the specific model. They are expensive to replace if lost therefore, you should keep extras handy. You can also find replacement keys fobs at various online stores and in a variety of brick-and-mortar automotive shops. But how to program a car key can you tell that the one you purchased is authentic? Are you able to tell whether it was programmed for another car or if it is able to be reprogrammed to fit your vehicle?
If you are planning to program a new key first, you need to make sure that your car is running. Insert the key you wish to reprogram into the ignition, but do not turn it. You will only have a couple of seconds before the car's system resets the commands and exits programming mode. Therefore, it is crucial to move quickly and not pause between steps. Turn off the engine to prevent this. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should be able to cycle, and you'll hear a chime signalling that the process has been successful.
Certain vehicles of recent years use rolling key technology to prevent thieves from using stolen keys to open the car. This feature is still vulnerable to a technique known as replay attack that allows thieves to record the signal from the vehicle's key fob, then reproduce it to open the car. To prevent this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded using an ordinary program. These types of vehicles will need to be programmed by a professional, so you should only try this only if you've worked with electronics. Consult your car's manual or visit the website of the manufacturer to find out how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming in order to work. While any hardware store can cut a new key for you, the main problem is to make it work with your specific car. The key must be programmed to match the exact identification number on your car, otherwise it won't start.
Transponder chips are a standard feature cost of programming a car key modern cars and are designed to stop car key programing theft. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car can detect the signal and starts the engine only if the signal matches the original one that was programmed in the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it much harder for novice car thieves to hot wire a vehicle and start it.
A circuit board with an induction coil connects the chip to the key. When the key is inserted into the ignition it creates a magnetic field around the transponder. This produces a signal which gets taken up by the coil, which transmits it to the key's identification number. The key's ID number is transmitted back to the vehicle and if it matches the engine will begin to run.

To accomplish this, you'll need scanners or computers with a USB port to identify the chip and establish its identity.

It is also recommended to avoid purchasing second-hand keys as they're probably already programmed and will not work with your vehicle.
