This is a security feature and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and the specific model. It's costly to replace them if they're lost, so it's a good idea 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. But how can you tell that the new key fob you bought is genuine? Do you know whether it was programmed for another car or if it could be reprogrammed to fit your vehicle? If you want to program a new key the first step is to ensure that your vehicle is running. Insert the key you wish to program into the ignition, but do not turn it. You only have just a few seconds before the car's system resets commands and exits programming mode. It is essential to move quickly and don't be patient between each step. 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 back to the "off" position. The door locks should be able to cycle, and you will hear a sound that indicates that the process was successful. Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the vehicle. This feature is still susceptible to a technique called replay attack. It allows thieves to record and then reproduce the signal from the car key fob to unlock the car. To combat this, manufacturers added the security feature known as the CAN bus protocols to prevent hacking. Some manufacturers use a special encryption on their keys, which cannot be decoded by a simple program. You should only try this method if your previous experience is in electronic devices. Check the manual of your car or look up the website of the manufacturer for information on how to program it. The steps are different depending on the type of vehicle. Transponder chips Transponder chip car keys require a special reprogramming to function. While any hardware store can cut a new key for you, the main problem is to make it work with your specific car. The key needs to be programmed to match the exact identification number of your vehicle, or else it will not start. Transponder chips are a typical feature of modern automobiles and are designed to prevent car theft. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is inserted. The car can detect the signal, and starts the engine only if the signal is in line with the original that was programmed in the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it. The chip and the key are connected by a circuit board that includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal that gets taken up by the coil, which then transmits it to key's identification number. The ID number of the key is then sent back to the vehicle, and if it is in line with the engine will begin to run. There are a variety of ways to program a transponder, but all require the use of a specific tool. You can purchase these tools on the internet or at many automotive locksmiths. These tools are not inexpensive, but they are vital for programming your car's chip. You could also use a unreprogrammable key that was programmed for another vehicle. In this instance, you'll need to make sure that the key isn't damaged or the transponder has been altered in any way. To check this, you can use scanners or a computer with an USB port to scan the chip and determine its identity. Reprogramming an transponder is a simple procedure, but it requires specific software. It also requires an scanner tool. If you're new to the process, it's best to seek the assistance of an auto locksmith.
