You can change the programming of your key fobs at home, however you must know the right process. To get the best results, you should have the following items:
Keys
The majority of modern vehicles require a transponder key to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with your car's system and specific model. It's expensive to replace them if they're lost, so it's best to keep extras on hand. You can purchase key fobs to replace them in online stores, as well as numerous brick-and-mortar auto shops. But how do you know that the one you purchased is genuine? Are you able to tell if it has been programmed to work with another vehicle or if it can be programmed to work with your car?
If you want to program a new key first, you need to ensure that your car is on and running. Insert the key that you'd like to reprogramme into the ignition, but don't turn it. You will only have a few seconds before the car's system resets the commands and then exits programming mode. It is crucial to be quick and don't delay between each step. To prevent this from happening, turn off the engine. Turn the key from "on" to "off" to test the system. The door locks should cycle and you will hear a chime signalling that the process was successful.
Certain cars with more modern technology have rolling key technology that stops thieves from using a stolen vehicle's key to open it. This feature is still vulnerable to a technique known as a replay attack, which allows thieves to record the signal received from the key fob of the car and then replicate it to open the car. To combat this, manufacturers introduced a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys, which can't be decoded with an ordinary program. You should only attempt this process if your experience is in electronics. It's a good idea to read your car's owner manual or look up the manufacturer on the internet, since the steps will differ depending on the car model.
Transponder chips
Car keys with transponder chips require a special programming to function. While any hardware store can cut a new key for you, the main challenge is making it function in conjunction with your particular car. The key has to be programmed to match the exact identification number of your car, or else it won't be able to start.
Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is put in 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 so that it will stop when it detects an incorrect frequency. This makes it more difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.
The chip and the key are connected via an electronic circuit board that contains an induction coil. When the key is put in the ignition the magnetic field is generated 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 identification code is transmitted back to the car and the engine will start if the identification number matches.
There are a variety of methods to program a key transponder, but each requires an instrument that is specifically designed for. These tools can be bought through the internet or from many automotive locksmiths. These tools aren't cheap but are essential for programming the chip in your car.

The process of reprogramming the transponder key is simple, however it requires special software and a scanning tool. If you're a beginner you should seek the assistance of an auto locksmith. Avoid buying used keys as they might already be programmed, and they won't be compatible with your vehicle.
