They can be costly to replace in the event of loss therefore, you should have spares in your car. You can find key fobs to replace them in online stores and many brick and mortar auto shops. But how can you tell that the one you have bought is authentic? Do you know whether it was programmed for a different vehicle or if it can be programmed to work with your car? To program a new car key, you must first ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. You will only have just a few seconds before the car's system reverts the commands and then exits programming mode. For this reason, it is crucial to move fast and not wait between steps. Shut off the engine to stop this. You can check the system of your car by turning the key to the "on" position, then back to the "off" position. The door locks should cycle, and you will hear a sound that indicates that the process has been successful. Certain newer vehicles have rolling key technology, which keeps thieves from using stolen cars' key to start it. This technology is still vulnerable to a method known as replay attack, which allows thieves to record the signal received from the vehicle's key fob and reproduce it later to unlock the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to stop hacking. Certain manufacturers have a unique encryption on their keys that can't be decoded with a simple program. It is best to only attempt this method if your previous experiences are with electronics. It's a good idea to read the owner's manual of your vehicle or search for the manufacturer online, as the steps will differ depending on the car model. Transponder chips Car keys that feature transponder chips require a special reprogramming to work. Any hardware store can make you a new car key but the real challenge lies in making it work with your car. The key you reprogrammed needs to be compatible with the specific identification number of the vehicle otherwise it won't even start the engine. Transponder chips, used to protect cars from theft, are a common feature of modern cars. The chip is a microcircuit which emits a radio frequency signal when the key is inserted in the ignition. The car then scans for the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it difficult for novice car thefts to wire a vehicle hot and then start it. A circuit board with an induction coil connects the chip to the key. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. This generates a signal that is taken up by the coil and sent to the key's identification. The key's identification number is then sent back to the car and the engine is started if the identification number matches.
