A key may have to be reprogrammed in the event that it is damaged or lost. You can reprogram your key fobs at home, however you need to be aware of the correct procedure. You should have these items to ensure the most effective results: Keys The majority of modern vehicles require a transponder keys to operate. This 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. It's costly to replace them if they are lost, so it's better to have spares available. You can locate key fobs to replace them in online stores as well as numerous brick-and-mortar auto shops. How can you be sure that the key you purchased is authentic? Do you know whether it was programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle? If you want to program a new key the first step is to make sure that your car is running. Insert the key you wish to program into the ignition, but don't turn it. You only have a few seconds before the car's system resets commands and exits programming mode. Therefore, it is crucial to move quickly and not wait between steps. Turn off the engine to prevent this. You can check the system of your car by turning the key to the "on" position and then back to the "off" position. You should hear a sound indicating that the process was successful. The door locks will go through a cycle. Certain newer vehicles have rolling key system, which stops thieves from using a stolen vehicle's key to start it. This feature is still vulnerable to a method known as a replay attack, which allows thieves to record the signal of the vehicle's key fob and reproduce it later to open the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to stop hacking. Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an easy program. You should only try this method if you have experience is with electronics. Refer to the manual for your car or look up the website of the manufacturer for information on how to program it. The steps are different depending on the model of vehicle. Transponder chips Car keys with transponder chips require a special reconfiguration to work. While any hardware store can cut a new key for you, the biggest issue is how to integrate it to work with the specific car you own. A key that has been reprogrammed will need to be compatible with the exact identification number of your car or else it won't be able to start the engine. Transponder chips are a standard feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is put in. The car detects the signal, and starts the engine only if the signal matches the original one that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it much more difficult for novice car thieves to connect a vehicle with hot wires and then start it. A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal, which is absorbed by the coil and sent to the key identification number. The key's identification number is returned to the car and the engine will start if the identification number matches. There are many methods to program a transponder keys, but they all involve using a special tool. You can purchase these tools online or at most automotive locksmiths. These tools aren't cheap but are essential for programming the chip in your car. You could also use a resettable key that was programmed for an alternative vehicle. In this case you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. To accomplish this, you'll need scanners or computers equipped with a USB port to identify the chip and establish its identity. Reprogramming an transponder is a simple procedure, but it requires special software. It also requires a scanner tool. It is recommended to contact an auto locksmith for help in case you're not an expert. Avoid buying used keys because they might already be programmed, and they won't work with your vehicle.
