Reprogramming Car Keys Transponders in car keys are thought to keep cars more secure and are more difficult for thieves to duplicate. A key may have to be programmed again in the event that it is damaged or lost. You can change the key fobs you own however, you must be aware of the proper procedure. You must have these things to ensure the most effective results: Keys Most modern vehicles require a transponder key or fob to work, which provides security and protection against theft. These keys must be programmed to your particular vehicle and its features by a licensed locksmith or dealer. It's expensive to replace them if they are lost, so it's a good idea to keep extras on hand. You will also find replacement key fobs on various websites and in a variety of brick-and-mortar automotive shops. But how do you know that the key fob you bought is genuine? Can you tell whether the unit has been programmed to work with another vehicle or if yours can be programmed again? If you want to program a new key, the first step is to ensure that your vehicle is on and running. Insert the key you wish to program into the ignition, but do not turn it. You will only have a few seconds before the car's system reverts the commands and leaves programming mode. For this reason, it is essential to move fast and not be able to wait between steps. To prevent this from happening, turn off the engine. 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 chime to indicate that the process was successful. Certain newer vehicles have rolling key technology that stops thieves from using a stolen vehicle's key to open it. This feature is still vulnerable to a technique called a replay attack. It allows thieves to record and later reproduce the signal from the vehicle key fob to unlock the car. To stop this, manufacturers added the security feature known as the CAN bus protocols to prevent hacking. Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by an ordinary program. You should only attempt this process if your experience is in electronics. It is a good idea to consult your car's owner manual or look up the manufacturer online, as the steps differ based on vehicle model. Transponder chips Car keys with transponder chips require a special programming to function. Any hardware store can make you a new car key but the real challenge lies in implementing it to your car. The key must be programmed to match the exact identification number on your car, or else it won't start. Transponder chips are a standard feature in modern cars and are designed to prevent car theft. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is put in. The car then recognizes the signal and then starts the engine in case it matches the original signal that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it difficult for novice car thefts to wire a vehicle hot and then start it. A circuit board equipped with an induction coil connects the key to the chip. When the key is placed in the ignition it creates an electric field around the transponder. This generates a signal that is amplified by the coil which then transmits it to key's identification number. The key's ID number is transmitted back to the vehicle and if it is in line with the engine will begin to run. There are many methods to program a transponder key, however, they all require a special tool. These tools can be bought online or from most automotive locksmiths. These tools aren't cheap but are essential for programming the chip in your car. You could also use a resettable 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 accomplish this, you'll need a scanner or a computer with a USB port to scan the chip and determine its identity. The process of reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. It is recommended to contact an auto locksmith for assistance if you're a novice. Avoid buying used keys as they may already be programmed and will not work with your vehicle.
