Keys
The majority of modern vehicles require a transponder key to operate. This is a security feature and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and the specific model. They can be costly to replace if lost therefore, you should have spares in your car. You can also find replacement key fobs at various online stores and in a variety of brick-and-mortar automotive shops. But how do you know that the new key fob you bought is genuine? Do you know whether it has been programmed for another car or if it could be programmed to work with your car?
To program a new car key, first make sure that your vehicle is running. Insert the key you'd like to program into the ignition, but do not turn it. There are just a few minutes before the system resets all commands and then exits the programming mode. It is crucial to be quick and don't be patient between each step. To avoid this happening, shut off the engine. You can check the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle and you'll hear a sound that indicates that the process has been successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the car. 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 unlock the car. To stop this, manufacturers have added security features known as the CAN bus protocols to prevent hacking.
Certain manufacturers have a unique encryption on their keys that can't be decoded with a simple program. You should only try this process if your experience is with electronic devices. Consult your car's manual or go to the manufacturer's website for information on how to program it. The steps to follow will differ according to the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. Any hardware store can offer you a new car key, however the real challenge lies in making it work with your car. A reprogrammed key will need to match the exact identification number of your car otherwise it won't even start the engine.
Transponder chips are a standard feature of modern cars and are designed to stop car theft. 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 starts the engine if it matches the original one that was programmed into the vehicle. The vehicle is also programmed to shut down when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
A circuit board with an induction coil connects the key to the chip. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This generates a signal that is taken up by the coil and then transmitted to the key identification number. The key's ID number is sent back to the vehicle, and if it matches, the engine will begin to run.

In this case you'll need sure that the key has not been damaged or the transponder has been altered in any way. To accomplish this, you'll need a scanner or a computer equipped with a USB port to identify the chip and establish its identity.

You should also avoid buying secondhand keys, as they're probably already programmed and will not be compatible with your car.
