Reprogramming Car Keys
Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. However, a key might need to be reprogrammed when it becomes damaged or lost.
You can change the programming of your key fobs at home, however you must be aware of the correct procedure. You should have these items to achieve the most effective results:
Keys
Modern cars require a transponder keys to operate. This provides security and anti-theft protection. The keys must 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 therefore, you should have spares in your car. You can also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you know that the key you purchased is authentic? Can you tell whether the unit is programmed to work with a different vehicle, or if it can be programmed differently?
If you want to program an entirely new key, the first step is to make sure that your car is on and running. Insert the key you wish to reprogramme into your ignition, but don't turn it. There are only a few seconds left before the system resets all commands and exits the programming mode. This is why it is essential to move quickly and not wait between steps. Turn off the engine to avoid this. You can check the car's security system by turning the key to the "on" position and back to the "off" position. The door locks should be able to cycle, and you will hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the car. This technology is still vulnerable to a method known as replay attacks, which allows thieves to record the signal of the vehicle's key fob and then replicate it to unlock the car. To prevent 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 which cannot be decoded by an easy program. These types of cars require programming by a professional. Therefore, you should only attempt this procedure only if you've worked with electronics. It is a good idea to consult your car's owner manual or look up the manufacturer online, as the steps will differ depending on the vehicle model.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. 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 code on your car, otherwise it won't be able to start.
Transponder chips, which are used to prevent car theft are a standard feature of modern automobiles. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car can detect the signal, and starts the engine only if the signal is in line with 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 hot-wire a vehicle and then start it.
A circuit board with an induction coil connects the key to the chip. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal that is absorbed by the coil, which transmits it to the key's identification number. The key's identification number is sent back to the car and the engine will start if the identification number matches.
There are many ways to program a transponder key however, they all require an appropriate tool. These tools are available online or from most automotive locksmiths. They're not cheap, but they are vital for programming the chip in your car.
You could also use a unreprogrammable key that was programmed for another vehicle. In this scenario, you'll need to make sure that the key isn't damaged or the transponder been altered in any way. You can read the chip by using a scanner or a computer equipped with the USB connector.
Reprogramming the transponder key is simple, however it requires an expertly designed software and scan tool. It is best to consult an auto locksmith for help if you're a novice. It is also recommended to avoid purchasing second-hand keys as they're probably already programmed and will not work with your car.
