Keys
Modern cars require a transponder key in order to operate. This gives security and protection against theft. The keys must be programmed to the specific vehicle and its systems by an authorized dealer or locksmith. They can be costly to replace if lost and it is recommended to keep spare keys in the car. You can find key fobs to replace them in online stores and many brick-and mortar auto shops. How can you ensure that the one 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 an entirely new key first, you need to make sure that your car is operating. Insert the key that you wish to reprogramme into the ignition, but don't turn it. There are just a few minutes before the system resets all commands and leaves the programming mode. For this reason, it is essential to move fast and not be able to wait between steps. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. The door locks should cycle and you will hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to open the car. The feature is still vulnerable to a technique dubbed replay attack. It allows thieves to record and reproduce the signal received from the vehicle key fob to unlock the car. To counter this, manufacturers have added an additional security feature known as the CAN bus protocol to stop hacking attempts.
Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an easy program. It is best to only attempt this process if your experiences are with electronics. It is a good idea to read the owner's manual of your vehicle or look up the manufacturer on the internet, since the steps differ based on vehicle model.
Transponder chips
Car keys that feature transponder chips need special reconfiguration to work. Any hardware store can give you a new car key but the real challenge is in integrating it with your vehicle. A reprogrammed key will need to be compatible with the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips, used to prevent car theft are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signal when the key is inserted in the ignition. The car is able to detect the signal and begins the engine only if it matches the one programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it difficult for thieves with no experience to hot-wire a vehicle and then turn it on.
A circuit board with an induction coil that connects the chip to the key. When the key is placed in the ignition, it creates a magnetic field around the transponder. This creates a signal which is taken up by the coil before being sent to the key identification number. The ID number of the key is then sent back to the vehicle, and if it matches the engine will begin to run.
There are a few different ways to program a transponder key but they all involve using a special tool. These tools can be purchased on the internet or at most auto locksmiths. They are not cheap, but they're vital for programming the chip to your vehicle.
You can also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this scenario you'll need to make sure that the key has not been damaged or that the transponder has been altered in any way. To do this, you'll need scanners or computers with a USB port to identify the chip and establish its identity.
The process of reprogramming an transponder's key is easy, but it will require special software and a scanning tool. If you're just beginning you should seek the assistance of an auto locksmith. You should also avoid buying second-hand keys as they're likely to be programmed and won't work with your vehicle.
