Reprogramming Car Keys
Car keys with transponders are believed to make vehicles safer and are harder for thieves to duplicate. However, keys may need to be reprogrammed in the event that it is damaged or lost.
You can reprogram key fobs yourself, but you must know the correct process. For the best results, you should have the following items:
Keys
Nearly all modern vehicles require a transponder key or fob in order to operate, ensuring security and anti-theft protection. The keys must be programmed to the specific vehicle and its systems by a licensed dealer or locksmith. They are costly to replace if they are lost, so you should have spares in your car. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how can you tell that the new key fob you bought is authentic? Do you know whether the unit has been programmed to work with a different vehicle, or if it can be programmed again?
If you want to program a new key the first step is to make sure that your car is running. Insert the key you'd like to program into the ignition, but do not turn it. You only have a few seconds before the car's system resets the commands and then exits programming mode. It is essential to move quickly and do not wait between each step. Shut off the engine to stop this. You can check the car's system by turning the key to the "on" position, then back to the "off" position. There should be a chime indicating that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the vehicle. This feature is still susceptible to a technique called a replay attack. It allows thieves to record and then duplicate the signal generated by the key fob of the vehicle to unlock the car. To prevent this, manufacturers introduced a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs which are not decoded by an ordinary program. It is best to only attempt this method if you have experience is in electronic devices. It is recommended to consult the owner's manual for your car or look up the manufacturer on the internet, since the steps differ based on vehicle type.
Transponder chips
Car keys with transponder chips need special reprogramming to work. Any hardware store can give you a new car key, but the real challenge is in making it work with your vehicle. The key needs to be programmed to match the exact identification number of your vehicle, or else it won't be able to start.
Transponder chips, used to stop theft of cars are a standard feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signal when the key is placed in the ignition. The car then scans for the signal and starts the engine if it matches the original frequency that was programmed into the vehicle. The vehicle is also programmed to shut down if it detects an invalid frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and 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, which is received by the coil and sent to the key's identification number. The key's ID number is sent back to the vehicle and if it matches, the engine will start.
There are a variety of ways to program a key transponder, but each requires the use of a specific tool. You can purchase these tools online or from most locksmiths for cars. These tools aren't expensive, but they are essential for programming the chip in your car.
You could also use a reprogrammable transponder key that was previously programmed for another vehicle. In this scenario you'll need to make sure that the key is not damaged or the transponder has been altered in any way. The chip can be read by using a scanner or a computer that has the USB connector.
Reprogramming the transponder key is easy, but it will require special software and a scanning tool. If you're a beginner it is recommended to seek the assistance of an auto locksmith. Avoid buying used keys because they might already be programmed, and they won't work with your vehicle.
