You can change the programming of your key fobs at home, but you should know the right process. You should have these items to ensure the most effective results:
Keys
Most modern cars require a transponder key in order to operate. This gives security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to work with your car's system and the specific model. It is expensive to replace them if they are lost, so it's better to have spares available. You can locate replacement key fobs in online stores and many brick and mortar auto shops. But how can you tell that the new one you purchased is authentic? Can you tell whether it was programmed for another car or if it is able to be reprogrammed to fit your vehicle?
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 program into the ignition, but do not turn it. There are just a few minutes before the system will reset all commands and exits the programming mode. It is crucial to move quickly and do not be patient between each step. To avoid this happening, turn off the engine. You can check the car's system by turning the key to the "on" position and back to the "off" position. You should hear a chime signalling that the procedure was successful. The door locks will go through a cycle.
Certain newer vehicles have rolling key technology, which prevents thieves from using stolen cars' key to start it. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and later duplicate the signal generated by the vehicle key fob to unlock the car. To prevent this, manufacturers have introduced an additional security feature known as the CAN bus protocol to stop hacking attempts.
Some manufacturers use a special encryption on their keys, which cannot be decoded by an easy program. These types of vehicles require to be programmed by a professional. Therefore, you should only attempt this process if you have experience working with electronics. It is recommended to refer to the owner's manual of your vehicle or look up the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys with transponder chips require a special reconfiguration to work. While any hardware store can cut a new key for you, the biggest challenge is making it function with your specific car. A key that has been reprogrammed will need to be matched with the specific identification number of your vehicle or else it won't be able to start the engine.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and starts the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and then start it.
A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal that is absorbed by the coil and then transmitted to the key identification number. The key's ID number is transmitted back to the vehicle and if it matches, the engine will start.
There are a variety of ways to program a key transponder, however all require an instrument that is specifically designed for. These tools can be bought on the internet or at most auto locksmiths. These tools aren't cheap but are essential for programming your car's chip.
You could also use a unreprogrammable key that was programmed for a different vehicle. In this scenario, ensure that the key hasn't been damaged or the transponder has not been altered in any way. You can read the chip by using a scanner or a computer that has the USB connector.
Reprogramming an transponder is a simple procedure, but requires specialized software. It also requires an scanner tool. If you're just beginning it is recommended to seek the assistance of an auto locksmith. Also, avoid buying second-hand keys as they're probably already programmed and will not work with your vehicle.
