You can reprogram your key fobs at home, but you should know the right process. For the best results, you should have the following items:
Keys
Most modern vehicles require some kind of transponder key or fob in order to operate, providing security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to function with your car's systems and specific model. They can be costly to replace if lost, so you should keep extras handy. You can also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you know that the one you purchased is genuine? Do you know whether the unit has been programmed to work with another vehicle, or if it can be reprogrammed?
To program a new car keys, you must first verify that your vehicle is running. Insert the key you wish to program into the ignition without turning it. You will only have a couple of seconds before the car's system reverts the commands and leaves programming mode. For this reason, it is important to be quick and not be able to wait between steps. Turn off the engine to avoid this. Switch the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will cycle.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to open the vehicle. This feature is still susceptible to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal from the car key fob to unlock the car. To prevent this, manufacturers have added the security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an easy program. You should only attempt this method if your previous experience is in electronic devices. Check the manual of your car or look up the website of the manufacturer to learn 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. While any hardware store can cut keys for you, the biggest challenge is making it function to work with the specific car you own. A key that has been reprogrammed will need to be matched with the exact identification number of the vehicle or else it won't be able to start the engine.
Transponder chips are a typical feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is placed into the ignition. The car then recognizes the signal and begins the engine if it matches the original one that was programmed into the vehicle. The car is also programmed to shut down when it detects an incompatible frequency. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then turn it on.
The key and the chip are connected by the circuit board which includes an induction coil. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This generates a signal, which is taken up by the coil and sent to the key identification number. The key's identification number is returned to the car, and the engine starts if the identification number matches.
There are several ways to program a transponder, but all of them require an instrument that is specifically designed for. You can purchase these tools online or at most locksmiths for cars. They are not cheap, but they're vital for programming the chip to your car.
You can also make use of a transponder key that can be reprogrammed that has been previously programmed for another vehicle. In this case you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. To check this, you can use a scanner or a computer equipped with an USB port to read the chip and determine its identity.
The process of reprogramming the transponder key is simple, however it requires specialized software and a scan tool. It is best to consult an auto locksmith for help in case you're not an expert. Avoid buying used keys because they might already be programmed, and they won't work with your car.

This is because in order to make modern keys function they must be "paired". This required expensive and complex equipment that was only available to dealers.
