The keys have to be programmed to your specific car and its systems by a licensed dealer or locksmith. It's costly to replace them if they're lost, so it's better to have spares in your possession. You can also find replacement keys fobs at various online stores and in a variety of brick-and-mortar automotive shops. How can you know that the key you purchased is genuine? Can you tell if it has been programmed for a different vehicle or if it can be reprogrammed for yours? If you want to program a new key, the first step is to ensure that your vehicle is operating. Insert the key you'd like to reprogramme into your ignition, but do not turn it. There are only a couple of seconds before the car's system resets the commands and leaves programming mode. For this reason, it is essential to be quick and not be able to wait between steps. To avoid this happening, shut off the engine. You can check the system of your car by turning the key to the “on” position and then back to the “off” position. You should hear a chime indicating that the process was successful. The door locks will cycle. Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to open the car. The technology is still susceptible to a technique known as a replay attack that allows thieves to record the signal of the key fob on the vehicle, then reproduce it to unlock the car. To prevent this, manufacturers added security features known as the CAN bus protocols to ward off hacking. Some manufacturers also use special encryption on their key fobs, which are not decoded by a simple program. You should only attempt this method if your previous experience is with electronics. It is a good idea to consult the owner's manual for your car or look up the manufacturer online, as the steps differ based on vehicle model. Transponder chips Car keys that feature transponder chips need special programming to function. While any hardware store can cut a new key for you, the biggest issue is how to integrate it in conjunction with your particular car. A key that has been reprogrammed will need to be matched with the specific identification number of your vehicle otherwise it won't even start the engine. Transponder chips, which are used to prevent car theft are a standard feature of modern automobiles. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car is able to detect the signal and begins the engine only if it matches the original that was programmed in the vehicle. The car is also programmed so that it will shut down when it detects an incorrect frequency. This makes it much harder for thieves who are not experienced to hot wire a vehicle and then start it. A circuit board with an induction coil connects the key to the chip. When the key is put in the ignition, a magnetic field is created around the transponder. This produces a signal which is absorbed by the coil, which transmits it to the key's identification number. The key's identification number is then transmitted back to the car and the engine is started if the identification number matches. There are many methods to program a transponder key but they all involve using an appropriate tool. These tools can be bought online or from most automotive locksmiths. These tools aren't expensive, but they are essential for programming the chip in your car.
