Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and harder to copy by thieves. A key may have to be reprogrammed in case of damage or lost.
You can change the programming of your key fobs at home, but you should be aware of the correct procedure. For the best results, you must have the following items:
Keys
Most modern vehicles require some kind of transponder key or fob in order to work, which provides security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to work with your car's system and specific model. They are costly to replace in the event of loss and it is recommended to keep spare keys in the car. You can purchase key fobs to replace them in online stores, as well as many brick-and mortar auto shops. How can you be sure that the one you bought is genuine? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be programmed differently?
To program a new car key, you must first ensure that your vehicle is running. Insert the key that you wish to reprogramme into the ignition, but do not turn it. You have just a few minutes before the system will reset all commands and leaves the programming mode. It is important that you be quick and don't wait between each step. Stop the engine to avoid this. Change the key from "on" to "off" to test the system. The door locks should be able to cycle, and you will hear a chime signalling that the process has been successful.
Certain newer vehicles have rolling key technology that stops thieves from using stolen cars' key to open it. The feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and then reproduce the signal from the key fob of the vehicle to open the car. To stop this, manufacturers have added a security feature called CAN bus protocol to thwart attacks on hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded by a simple program. These kinds of cars require to be programmed by a professional, and you should only attempt this process with someone who has experience with electronic devices. It is a good idea to refer to your car's owner manual or search for the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Car keys that feature transponder chips need special programming to function. Any hardware store can offer you an entirely new car key, but the real challenge is in implementing it to your car. The key you reprogrammed needs to match the exact identification number of your vehicle or else it won't be able to start the engine.
Transponder chips, used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit which emits a radio frequency signal when the key is put in the ignition. The car detects the signal and begins the engine only if the signal is in line with the original that was programmed in the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for car thieves with no experience to connect a vehicle with hot wires and start it.
The chip and the key are connected by a circuit board that includes an induction coil. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is amplified by the coil which then transmits it to key's identification number. The key's identification number is returned to the car and the engine is started if the identification number matches.
There are many ways to program a transponder key however, all require a special tool. You can purchase these tools online or at most automotive locksmiths. They are not cheap, but they're crucial for programming the chip to your vehicle.
You may also use a unreprogrammable key that was programmed for another vehicle. In this scenario, ensure that the key has not been damaged or that the transponder isn't altered in any way. To check this, you'll need a scanner or a computer equipped with an USB port to identify the chip and establish its identity.
Reprogramming an transponder is a simple procedure, but it requires specific software. It also requires an scanner tool. If you're a beginner it is recommended to seek out the help of an auto locksmith. Avoid buying used keys because they may already be programmed, and they won't work with your car.
