Reprogramming programming car key are said to be more secure for cars and harder to copy by thieves. However, a key might require reprogramming when it becomes damaged or lost.
You can program key fobs yourself, but you must know the proper procedure. To get the best results, you'll need the following items:
Keys
Modern cars require a transponder keys to operate. This is a security feature and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to work with the car's systems and specific model. They can be costly to replace in the event of loss, so you should keep extras handy. You can also find replacement keys fobs on various websites and in many brick-and-mortar auto shops. How can you know that the one you bought is authentic? Can you tell whether it has been programmed for another car or if it could be programmed to work with your car?
To program a new car keys, you must first ensure that your vehicle is operating. Insert the key you wish to reprogram into the ignition without turning it. There are only a few seconds left before the system will reset all commands and then exits the programming mode. Therefore, it is crucial to move fast and not pause between steps. To avoid this happening, turn off the engine. Switch the key from "on" to "off" to test the system. You should hear a sound indicating that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique dubbed replay attacks that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to stop attacks on hacking.
Certain manufacturers also employ special encryption on their key fobs, that cannot be decoded with an easy program. It is best to only attempt this method if your previous experience is in electronic devices. Refer to the manual for your car or go to the manufacturer's website to learn how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming in order to work. While any hardware store can cut a new key for you, the biggest problem is to make it work in conjunction with your particular car. The key you reprogrammed needs to be compatible with the specific identification number of your car, or it won't start the engine.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car can detect the signal and starts the engine only if it matches the one programmed in the vehicle. The car is also programmed to shut down if it detects an invalid frequency. This makes it difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.
The chip and the key are linked by an electronic circuit board that contains an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal that gets absorbed by the coil, which transmits it to the key's identification number. The key's identification number is then transmitted back to the car and the engine will start when the identification number matches.
There are a variety of methods to program a key transponder, but each requires the use of a specific tool. You can buy these tools online or from most locksmiths for cars. They are not cheap, but they are essential for programming the chip into your car.
You could also use a resettable key that was programmed for a different vehicle. In this case you'll need sure that the key isn't damaged or that the transponder has been altered in any way. You can read the chip using a scanner, or a computer equipped with an USB connector.
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 help from an auto locksmith. It is also recommended to avoid purchasing second-hand keys as they're likely to be programmed and will not work with your vehicle.
