Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. A key may have to be reprogrammed in event that it is damaged or lost.
You can change the programming of your key fobs at home, however you should be aware of the proper procedure. For the best results, you'll need the following items:
Keys
Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. It's costly to replace them if they become lost, so it's better to keep extras on hand. You can also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How do you ensure that the new key fob you bought is authentic? Do you know whether the unit is programmed to work with a different vehicle, or if it can be programmed differently?
To program a new car keys, you must first ensure that your vehicle is running. Insert the key you want to reprogram into the ignition, but do not turn it. You will only have just a few seconds before the car's system resets the commands and exits programming mode. This is why it is essential to move quickly and not be able to wait between steps. Shut off the engine to stop this. You can test the car's security 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 to indicate that the procedure was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique known as a replay attack which allows thieves to record the signal of the key fob of the car and then replicate it to open the car. To prevent this, manufacturers have introduced an additional security feature known as the CAN bus protocol to prevent attacks on hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded using an ordinary program. These types of vehicles require programming by a professional. Therefore, you should only try this if you have experience working with electronics. Consult your car's manual or look up the manufacturer's website for information on how to program it. The steps to follow will differ depending on the model of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. Any hardware store can offer you an entirely 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 on your vehicle, or else it won't be able to start.
Transponder chips are a common feature of modern automobiles and are designed to stop car theft. The chip is a small microcircuit that emits a radio frequency signal when the ignition key is put in. The car then detects the signal and then starts the engine if it matches the original signal that was programmed into the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it difficult for thieves with no experience to hot-wire a vehicle and then start it.
The chip and the key are connected by an electronic circuit board that contains an induction coil. When the key is inserted into the ignition it creates a magnetic field 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 ID number is transmitted back to the vehicle, and if it is in line with the engine will begin to run.
There are many methods to program a key transponder, but all require an instrument that is specifically designed for. You can purchase these tools on the internet or at many locksmiths in the automotive industry. They are not cheap, but they are vital for programming the chip into your vehicle.
You can also use an resettable key that was programmed for an alternative vehicle. In this case, you'll need to make sure that the key has not been damaged or the transponder been altered in any way. The chip can be read with a scanner, or a computer with a USB connector.
Reprogramming a transponder is a simple process, but requires specific software. It also requires an scanner tool. If you're just beginning you should seek out the help of an auto locksmith. Also, avoid buying secondhand keys, as they're probably already programmed and won't work with your vehicle.
