Keys
The majority of modern vehicles require a transponder key in order to operate. This provides security and anti-theft protection. The keys must be programmed to your specific car and its systems by an authorized dealer or locksmith. It's expensive to replace them if they are lost, so it's best to keep extras on hand. You can also find replacement key fobs on various websites and in a variety of brick-and-mortar automotive shops. How can you know that the one you purchased is genuine? Can you tell whether it has been programmed for another car or if it is able to be reprogrammed to fit your vehicle?
If you are planning to program a new key the first step is to ensure that your car is on and running. Insert the key you wish to program into the ignition, but do not turn it. There are only a few seconds before the system will reset all commands and then exits the programming mode. It is crucial to move quickly and don't be patient between each step. Stop the engine to prevent this. You can test the system of your car by turning the key to the "on" position, then back to the "off" position. You should hear a chime signalling that the procedure was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the car. This feature is still susceptible to a technique dubbed a replay attack. It allows thieves to record and later duplicate the signal generated by the vehicle key fob to open the car. To prevent this, manufacturers introduced the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys that can't be decoded with an easy program. You should only attempt this method if you have experience is with electronics. Consult your car's manual or go to the manufacturer's website to learn how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys with transponder chips require special reconfiguration to work. Any hardware store can give you a new car key however the real challenge lies in implementing it to your car. The key you reprogrammed needs to match the exact identification number of the vehicle, or it won't start the engine.
Transponder chips, which are used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the ignition key is put in. The car then scans for the signal and begins the engine in case it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it more difficult for thieves who are not experienced to wire a vehicle and start it.
The key and the chip are connected by a circuit board that includes an induction coil. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This generates a signal that gets amplified by the coil which transmits it to the key's identification number. The key's identification number is transmitted back to the car and the engine is started if the identification number matches.
There are many ways to program a key transponder, but all require an instrument that is specifically designed for. You can buy these tools online or from most locksmiths for cars. They're not cheap, but they're essential for programming the chip in your car.
You can also use an reprogrammable key that was previously programmed for a different vehicle. In this scenario you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. The chip can be read by using a scanner or a computer with the USB connector.
Reprogramming an transponder's key is simple, however it requires special software and a scanning tool. If you're a beginner it is recommended to seek help from an auto locksmith. Don't buy used keys since they might already be programmed and won't work with your car.
