Reprogramming Car Keys Transponder keys are thought to be more secure for cars and are more difficult to copy by thieves. However, a key may need to be reset if it becomes damaged or lost. You can program key fobs yourself but you must be aware of the proper procedure. To get the best results, you must have the following items: Keys Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. The keys have to be programmed to your particular vehicle and its systems by a certified dealer or locksmith. They are costly to replace in the event of loss, so it is recommended to keep spare keys in the car. You can purchase key fobs to replace them in online stores as well as numerous brick-and-mortar auto shops. But how can you tell that the one you purchased is genuine? Do you know whether it has been programmed to work with another vehicle or if it could be programmed to work with your car? If you are planning to program a new key the first step is to ensure that your vehicle is operating. Insert the key you want to reprogram 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 leaves programming mode. It is essential to be quick and don't be patient between each step. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. There should be a chime to indicate that the process was successful. The door locks will be able to cycle. Certain cars with more modern technology have rolling key system, which stops 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 then replicate it to open the car. To stop this, manufacturers have added an additional security feature known as the CAN bus protocol to prevent hacking attempts. Certain manufacturers also employ special encryption on their key fobs which are not decoded by an easy program. You should only try this process if your experience is with electronic devices. It is recommended to read the owner's manual of your vehicle or search for the manufacturer online, as the steps differ based on vehicle type. Transponder chips Transponder chip car keys require a special reprogramming to function. Any hardware store can offer you an entirely new car key, however the real challenge lies in implementing it to your vehicle. The key you reprogrammed needs to be compatible with the specific identification number of your vehicle, or it won't start the engine. Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is inserted in the ignition. The car then detects the signal and begins the engine if it is in line with the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it difficult for novice car thefts to hot-wire a vehicle 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 electric field around the transponder. This creates a signal which is received by the coil and then transmitted 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 methods to program a key transponder, however all of them require a special tool. These tools are available online or from most automotive locksmiths. These tools aren't expensive, but they are essential for programming the chip in your car. You can also use an reprogrammable key that was previously programmed for an alternative vehicle. In this scenario, make sure that the key has not been damaged or the transponder has not been altered in any way. To accomplish this, you can use a scanner or a computer with an USB port to identify the chip and establish its identity. Reprogramming the transponder is a straightforward process, but requires special software. It also requires an scanner tool. It is best to consult an auto locksmith for help for those who are new to the process. Avoid buying used keys because they might already be programmed, and they won't be compatible with your vehicle.
