Keys

You only have a couple of seconds before the car’s system resets the commands and leaves programming mode. This is why it is important to move quickly and not pause between steps. Stop the engine to stop this. 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 has been successful.
Certain newer vehicles have rolling key technology that stops thieves from using a stolen vehicle’s key to open it. This feature is still vulnerable to a method known as a replay attack that allows thieves to record the signal of the vehicle’s key fob, then reproduce it to open the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to prevent attacks on hacking.
Certain manufacturers also employ special encryption on their key fobs which are not decoded by a simple program. These kinds of cars require programming by a professional, and you should only try this with someone who has experience with electronic devices. It is recommended to refer to your car’s owner manual or look up the manufacturer on the internet, since these steps vary by vehicle type.
Transponder chips
Car keys that feature transponder chips require a special reprogramming to work. While any hardware store can cut keys for you, the main challenge is making it function to work with the specific car you own. The key you reprogrammed needs to be matched with the exact identification number of your vehicle, or it won’t start the engine.
Transponder chips, which are used to stop theft of cars are a standard feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signals when the key is placed into the ignition. The car is able to detect the signal and starts the engine only if it matches the original one that was programmed in the vehicle. The car is also programmed so that it will shut down when it detects an incompatible frequency. This makes it harder for thieves who aren’t experienced to connect a vehicle to a hot wire and then start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This generates a signal that is taken up by the coil, which sends it to the key’s identification number. The ID number of the key is then sent back to the vehicle, and if it matches, the engine will start.
There are several ways to program car key a transponder key but they all involve using an instrument that is specifically designed for the purpose. These tools can be bought on the internet or at most auto locksmiths. They are not cheap, but they are vital for programming the chip to your vehicle.

To do this, you’ll need scanners or computers equipped with a USB port to scan the chip and determine its identity.
The process of reprogramming a transponder key is quite simple, but it requires an expertly designed software and scan tool. If you’re a beginner, it’s best to seek help from an auto locksmith. Avoid buying used keys as they might already be programmed, and they won’t work with your vehicle.
