You can reprogram key fobs yourself however, you must be aware of the correct procedure. To get the best results, you must have the following items:
Keys
Most modern vehicles require some kind of transponder fob or transponder keys to work, which provides security and anti-theft protection. The keys have to be programmed to your particular vehicle and its features by a certified dealer or locksmith. It's expensive to replace them if they're lost, so it's a good idea to have spares in your possession. You can find key fobs that can be replaced in online stores as well as numerous brick-and-mortar auto shops. How can you ensure that the one you bought is authentic? Do you know whether the unit is programmed to work with a different vehicle or if it could be reprogrammed?
If you are planning to program a new key first, you need to ensure that your car is operating. Insert the key you want to program into the ignition without turning it. There are only a couple of seconds before the car's system reverts the commands and then exits programming mode. Therefore, it is important to move fast and not be able to wait between steps. Stop 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. There should be a chime signalling that the procedure was successful. The door locks will cycle.
Certain newer vehicles have rolling key technology, which stops thieves from using a stolen vehicle's key to start it. The feature is still vulnerable to a technique known as replay attack. It allows thieves to record and later reproduce the signal received from the vehicle key fob to unlock the car. To combat this, manufacturers introduced a security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs, which are not decoded by an ordinary program. These types of cars require to be programmed by a professional, so you should only try this if you have experience working with electronic devices. It is recommended to read the owner's manual for your car or look up the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Transponder chip car keys require special reprogramming in order to function. Any hardware store can offer you an entirely new car key, but the real challenge is in implementing it to your car. The key has to be programmed to match the exact identification number on your vehicle, or else it will not start.
Transponder chips, which are used to stop theft of cars, are a common feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is placed in the ignition. The car is able to detect the signal, and starts the engine only if the signal is in line with the original one that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it much more difficult for car thieves with no experience to wire a vehicle and start it.
A circuit board that has an induction coil that connects the key to the chip. When the key is put in the ignition the magnetic field is generated around the transponder. This creates a signal that gets taken up by the coil, which then transmits it to key's identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will start.
There are programming car key to program a key transponder, however all of them require the use of a specific tool. These tools are available on the internet or at most auto locksmiths. They are not cheap, but they're essential for programming the chip in your car.

Reprogramming the transponder key is simple, but it requires special software and a scanning tool. If you're new to the process you should seek the assistance of an auto locksmith. It is also recommended to avoid purchasing second-hand keys, since they're probably already programmed and will not work with your vehicle.
