You can change the key fobs you own however, you must be aware of the correct procedure. For the best results, you should have the following items:
Keys
Most modern cars require a transponder key to operate. This gives security and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to work with your car's systems and the specific model. It's costly to replace them if they become lost, so it's best to have spares available. You can locate replacement key fobs in online stores as well as many brick-and mortar auto shops. But how do you know that the new key fob you bought is authentic? Do you know whether it has been programmed to work with another vehicle or if it can be reprogrammed to fit your vehicle?
If you are planning to program an entirely new key first, you need to make sure that your car is running. Insert the key that you wish to reprogramme into your ignition, but don't turn it. You have just a few minutes before the system will reset all commands and leaves the programming mode. This is why it is crucial to move fast and not wait between steps. Turn off the engine to prevent this. Switch the key from "on" to "off" to test the system. The door locks should cycle, and you will hear a sound that indicates that the procedure was successful.
Some newer cars use a rolling key technology, which stops thieves from using a stolen car's key to start it. This feature is still susceptible to a technique known as replay attack. It allows thieves to record and then reproduce the signal received from the vehicle key fob to open the car. To stop this, manufacturers have added the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

Transponder chips
Car keys that feature transponder chips require special programming to function.

The key needs 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 standard feature of modern cars. The chip is a small microcircuit which transmits a radio-frequency signal when the ignition key is placed. 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 in the vehicle. The car will also shut down if a frequency is not valid. This makes it harder for thieves with no experience to wire a vehicle hot and then start it.
The chip and the key are connected by a circuit board that includes an induction coil. When the key is put in the ignition the magnetic field is generated around the transponder. This generates a signal, which is received by the coil and then transmitted to the key's identification. The key's identification number is then returned to the car and the engine is started when the identification number is in line with.

To accomplish this, you'll need scanners or a computer equipped with an USB port to identify the chip and establish its identity.
Reprogramming an transponder's key is simple, but it requires special software and a scanning tool. It's best to ask an auto locksmith for help if you're a novice. Also, avoid buying second-hand keys as they're likely to be programmed and will not work with your car.
