You can reprogram key fobs yourself however, you must be aware of the proper procedure. To get the best results, you'll need the following items:
Keys
Most modern cars require a transponder key to operate. This provides security and anti-theft protection. These keys must be programmed to your particular vehicle and its systems by an authorized dealer or locksmith. It's costly to replace them if they become lost, so it's a good idea to keep extras on hand. You can also find replacement keys fobs in various online stores and in many brick-and mortar auto shops. How can you be sure that the one you bought is authentic? Do you know whether the unit has been programmed to work with a different vehicle or if it could be programmed again?
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 resets commands and then exits programming mode. For this reason, it is crucial to move fast and not wait between steps. Turn off the engine to stop this. You can test 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 sound that indicates that the process was 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 a replay attack, which allows thieves to record the signal received from the vehicle's key fob and then replicate it to open the car. To stop this, manufacturers introduced a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Some manufacturers also use special encryption on their key fobs which cannot be decoded by an easy program. These types of vehicles require to be programmed by a professional, and you should only try this if you have experience working with electronics.

The key has to be programmed to match the exact identification number of your car, otherwise it won't be able to start.
Transponder chips, which are used to protect cars from theft, are a common feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted in the ignition. The car detects the signal and begins the engine only if it matches the one programmed in the vehicle. The car also shuts down if a frequency is invalid. This makes it more difficult for thieves with no experience 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 placed in the ignition it creates an electromagnetic field around the transponder. This creates a signal which is absorbed by the coil before being sent to the key identification number. The key's ID number is transmitted back to the vehicle and if it is in line with the engine will begin to run.

In this instance, you must ensure that the key isn't damaged or that the transponder isn't altered in any way. You can read the chip with a scanner, or a computer equipped with the USB connector.
Reprogramming a transponder key is quite easy, but it will require an expertly designed software and scan tool. It is best to consult an auto locksmith for assistance if you're a novice. It is also recommended to avoid purchasing second-hand keys as they are likely already programmed and won't work with your car.
