You can change the key fobs you own however, you must be aware of the correct procedure. You must have these things to achieve the most effective results:
Keys
Most modern vehicles require some kind of transponder fob or transponder keys to work, which provides security and anti-theft protection. These keys must be programmed to your specific car and its systems by a licensed locksmith or dealer. It's expensive to replace them if they're lost, so it's best to keep extras on hand. You can find replacement key fobs in online stores and many brick and mortar auto shops. But how do you know that the key fob you bought is authentic? Can you tell whether it has been programmed for a different vehicle or if it is able to be programmed to work with your car?
If you want to program a new key the first step is to ensure that your car is operating. Insert the key that you'd like to reprogramme into the ignition, but don't turn it. You will only have just a few seconds before the car's system resets commands and exits programming mode. For this reason, it is crucial to be quick and not pause between steps. Turn off the engine to avoid this. Change the key from "on" to "off" to test the system. You should hear a chime to indicate that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the vehicle. This technology is still vulnerable to a method known as replay attack that allows thieves to record the signal from the key fob on the vehicle and then replicate it to open the car. To stop this, manufacturers added the security feature known as the CAN bus protocols to prevent hacking.
Certain manufacturers also have special encryption on their key fobs, which cannot be decoded by a simple program. These types of vehicles require to be programmed by a professional. Therefore, you should only attempt this procedure with someone who has experience with electronics. Consult your car's manual or go to the manufacturer's website to find out how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the real problem is to make it work with your specific car. The key must be programmed to match the exact identification number of your car, otherwise it won't be able to start.
Transponder chips, used to stop theft of cars are a standard feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted into the ignition. The car then recognizes the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it much more difficult for novice car thieves to hot wire a vehicle and start it.
A circuit board equipped with an induction coil connects the chip to the key. When the key is put in the ignition it creates a magnetic field created around the transponder. This produces a signal which is absorbed by the coil, which then transmits it to key's identification number. The key's identification number is sent back to the car and the engine will start when the identification number is in line with.
There are many ways to program a transponder, but all require an instrument that is specifically designed for. These tools can be purchased through the internet or from many automotive locksmiths. They are not cheap, but they're crucial for programming the chip in your car.
You may also make use of a transponder key that can be reprogrammed that has been previously programmed for another vehicle. In this scenario, make sure the key has not been damaged or the transponder has not been altered in any way. To do this, you can use scanners or computers equipped with a USB port to read the chip and determine its identity.
Reprogramming an transponder's key is easy, but it will require special software and a scanning tool. If you're a beginner it is recommended to seek help from an auto locksmith. Avoid buying used keys as they could already be programmed and will not be compatible with your vehicle.
