Reprogramming Car Keys Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. However, a key might require reprogramming when it becomes damaged or lost. You can reprogram key fobs yourself, but you must know the correct process. For the best results you'll need the following items: Keys Most modern vehicles require some kind of transponder fob or transponder keys to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to function with your car's systems and the specific model. They can be costly to replace in the event of loss, so you should keep extras handy. You can also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How do you ensure that the key fob you bought is genuine? Do you know whether it has been programmed for a different vehicle or if it could be programmed to work with your car? To program a new car keys, you must first ensure that your car is running. Insert the key you want to reprogram into the ignition, but do not turn it. You have only a few seconds left before the system resets all commands and exits the programming mode. It is crucial to move quickly and don't wait between each step. To prevent this from happening, shut off the engine. You can test the system of your car by turning the key to the "on" position and back to the "off" position. There should be a chime to indicate that the process was successful. The door locks will cycle. Some newer cars use a rolling key system, which prevents thieves from using a stolen car's key to start it. The technology is still susceptible to a technique dubbed replay attack that allows thieves to record the signal received from the key fob of the car and reproduce it later to unlock the car. To combat this, manufacturers introduced security features known as the CAN bus protocols to ward off hackers from gaining access to the vehicle. Certain manufacturers have a unique encryption on their keys that cannot be decoded by an easy program. These types of vehicles require programming by a professional, and you should only attempt this procedure only if you've worked with electronics. Consult your car's manual or visit the website of the manufacturer to find out how to program it. The steps to follow will differ depending on the model of vehicle. Transponder chips Transponder chip car keys require a special reprogramming to work. While any hardware store can cut a new key for you, the main problem is to make it work to work with the specific car you own. A reprogrammed key will need to match the specific identification number of your vehicle or else it won't be able to start the engine. Transponder chips are a typical feature in modern cars and are designed to guard against car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is put into the ignition. The car then scans for the signal and starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car is also programmed to shut down if it detects an invalid frequency. This makes it harder for novice car thefts to connect a vehicle to a hot wire and then turn it on. A circuit board that has an induction coil connects the chip to the key. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This creates a signal which is received by the coil and sent to the key's identification number. The key's ID number is then sent back to the vehicle and if it matches, the engine will begin to run. There are many ways to program a transponder, but all of them require a special tool. These tools can be bought on the internet or at most auto locksmiths. They're not cheap, but they are essential for programming the chip into your car. You can also use an reprogrammable key that was previously programmed for another vehicle. In this instance you'll need sure that the key isn't damaged or the transponder been altered in any way. To accomplish this, you'll need scanners or computers equipped with an USB port to scan the chip and determine its identity. The process of reprogramming the transponder key is simple, however it requires specialized software and a scan tool. If you're new to the process, it's best to seek the assistance of an auto locksmith. Don't buy used keys since they might already be programmed and won't work with your vehicle.
