Reprogramming Car Keys
Transponders in car keys are thought to keep vehicles more secure and harder for thieves to duplicate. The key could need to be reprogrammed in event of damage or lost.
You can reprogram key fob (their explanation) key fobs yourself but you must be aware of the correct process. To get the best results, you'll need the following items:
Keys
Modern cars require a transponder key to operate. This provides security and protection against theft. These keys must be programmed to your specific car and its systems by an authorized dealer or locksmith. They are costly to replace in the event of loss therefore, you should keep extras handy. You can locate key fobs to replace them in online stores and many brick and mortar auto shops. But how to program a car key can you tell that the new one you purchased is authentic? Do you know whether the unit is programmed to work with another vehicle, or if it can be programmed differently?
To program a new car key first make sure that your car is running. Insert the programing key you want to program into the ignition without turning it. You only have just a few seconds before the car's system resets the commands and then exits programming mode. It is crucial to be quick and don't wait between each step. Turn off the engine to prevent this. You can test the car's 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'll hear a chime signalling that the process was successful.
Certain vehicles of recent years use rolling key technology to prevent thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique dubbed replay attacks that allows thieves to record the signal received from the vehicle's key fob and then replicate it to unlock the car. To combat this, manufacturers introduced a security feature known as the CAN bus protocols to ward off hacking.
Some manufacturers also use special encryption on their key fobs that cannot be decoded with a simple program. These types of cars will need to be programmed by a professional, so you should only attempt this procedure only if you've worked with electronics. It is recommended to refer to your car's owner manual or search for the manufacturer online, as the steps differ based on vehicle type.
Transponder chips
Car keys that feature transponder chips require special reconfiguration to work. While any hardware store can cut and program car key keys for you, the real challenge is making it function in conjunction with your particular car. The key must be programmed to match the exact identification number of your vehicle, or else it will not start.
Transponder chips, used to prevent car theft are a standard feature of modern automobiles. The chip is a microcircuit that emits a radio frequency signal when the key is placed into the ignition. The car then scans for the signal and starts the engine in case it matches the original frequency that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it difficult for thieves with no experience to wire a vehicle hot and then start it.
A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition it creates a magnetic field around the transponder. This creates a signal that is absorbed by the coil, which sends it to the key's identification number. The key's identification number is then transmitted back to the car and the engine will start if the identification number matches.
There are a variety of ways to program a key transponder, however all require the use of a specific tool. These tools are available on the internet or at most auto locksmiths. They're not cheap, but they're crucial for programming the chip in your car.
You may also use a unreprogrammable key that was programmed for another vehicle. In this instance, you must ensure that the key hasn't been damaged or the transponder has not been altered in any way. The chip can be read by using a scanner or a computer equipped with the USB connector.
The process of reprogramming a transponder key is quite easy, but it will require specialized software and a scan tool. If you're just beginning, it's best to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they're probably already programmed and will not work with your car.
