Reprogramming Car Keys
Transponders in car keys are believed to make cars more secure and are less likely to be duplicated by thieves. However, keys may need to be reset if it becomes damaged or lost.
You can reprogram key fobs yourself, but you must know the proper procedure. For the best results you should have the following items:
Keys
Nearly all modern vehicles require some kind of transponder key or fob in order to operate, ensuring security and protection against theft. These keys are programmed by a locksmith or authorized dealer to function with your car's systems and specific model. It's expensive to replace them if they are lost, so it's best to have spares in your possession. You can locate key fobs that can be replaced in online stores, as well as numerous brick-and-mortar auto shops. But how do you know that the new key fob you bought is authentic? Do you know whether the unit is programmed to work with a different vehicle or if yours can be programmed again?
If you're looking to program a new key, the first step is to make sure that your car is running. Insert the key you want to reprogram into the ignition without turning it. You have only a few seconds left before the system will reset all commands and exits the programming mode. Therefore, it is crucial to move quickly and not wait between steps. To prevent this from happening, turn off the engine. You can check the car's system by turning the key to the "on" position and back to the "off" position. You should hear a sound indicating that the process was successful. The door locks will be able to cycle.
Some newer vehicles use rolling keys to stop thieves from using stolen keys to open the car. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and later duplicate the signal generated by the key fob of the vehicle to open the car. To stop this, manufacturers added security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an ordinary program. You should only try this method if your previous experience is in electronics. Consult your car's manual or go to the manufacturer's website 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 work. Any hardware store can make you an entirely new car key, but the real challenge lies in making it work with your car. The key has to be programmed to match the exact identification number on your vehicle, or else it won't start.
Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car then recognizes the signal and then starts the engine if it matches the original one that was programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it harder for thieves with no experience to wire a vehicle hot and then turn it on.
A circuit board that has an induction coil that connects the key to the chip. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This produces a signal which gets amplified by the coil which transmits it to the key's identification number. The ID number of the key is sent back to the vehicle, and if it matches the engine will start.
There are many methods to program a transponder key, however, all require an instrument that is specifically designed for the purpose. These tools can be purchased online or from most automotive locksmiths. These tools aren't expensive, but they are essential to program your car's chip.
