Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. However, a key might need to be reprogrammed if it becomes damaged or lost.
You can change the key fobs you own but you must be aware of the correct procedure. For the best results, you'll need the following items:
Keys
The majority of modern vehicles require a transponder key in order to operate. This provides security and anti-theft protection. The keys have to be programmed to your specific vehicle and its systems by an authorized locksmith or dealer. They can be costly to replace if they are lost and you should have spares in your car. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. But how do you know that the one you have bought is authentic? Can you tell whether it has been programmed to work with another vehicle or if it is able to be programmed to work with your car?
To program a new car key you must first verify that your car is running. Insert the key you want to reprogramme into your ignition, but do not turn it. You only have a couple of seconds before the car's system reverts the commands and then exits programming mode. This is why it is essential to be quick and not be able to wait between steps. To prevent this from happening, turn off the engine. You can test the system of your car by turning the key to the "on" position and back to the "off" position. You should hear a chime indicating that the process was successful. The door locks will be able to cycle.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique called a replay attack. It allows thieves to record and then duplicate the signal generated by the vehicle key fob to unlock the car. To stop this, manufacturers introduced security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs which are not decoded by a simple program. You should only try this method if your previous experience is with electronics. Refer to the manual for your car or visit the manufacturer's website for information on how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge is in implementing it to your car. The key needs to be programmed to match the exact identification number of your car, or else it won't start.
Transponder chips are a typical feature of modern cars and are designed to guard against car theft. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal, and starts the engine only if the signal matches the original one that was programmed in the vehicle. The car will also shut down if a frequency is not valid. This makes it much harder for novice car thieves to connect a vehicle with hot wires and then start it.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This creates a signal that gets absorbed by the coil, which then transmits it to key's identification number. The key's ID number is sent back to the vehicle and if it matches the engine will begin to run.
There are a variety of ways to program a transponder, but all require an instrument that is specifically designed for. You can buy these tools on the internet or at many locksmiths in the automotive industry. These tools are not inexpensive, but they are vital to program your car's chip.
You could also use a unreprogrammable key that was programmed for another vehicle. In this instance, you must make sure that the key has not been damaged or that the transponder has not been altered in any way. To do this, you'll need scanners or a computer equipped with a USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple process, but requires specialized software. It also requires an scanner tool. If you're a beginner you should seek the assistance of an auto locksmith. Don't buy used keys since they might already be programmed and will not be compatible with your vehicle.
