You can reprogram your key fobs at home, but you should know the right process. You should have these items to get the best results:
Keys
Nearly all modern vehicles require a transponder key or fob in order to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with your car's systems and the specific model. They can be costly to replace if lost therefore, it is recommended to keep spare keys in the car. You can also find replacement key fobs in various online stores and in many brick-and-mortar auto shops. How can you ensure that the key you purchased is authentic? Can you tell whether the unit has been programmed to work with another vehicle or if it could be programmed differently?
If you're looking to program an entirely new key the first step is to ensure that your car is running. Insert the key that you'd like to reprogramme into your ignition, but don't turn it. You have only a few seconds left before the system will reset all commands and then exits the programming mode. It is essential to move quickly and do not be patient between each step. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. You should hear a sound indicating that the process was successful. The door locks will be able to cycle.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the car. This feature is still vulnerable to a method known as replay attack that allows thieves to record the signal received from the vehicle's key fob, then reproduce it to unlock the car. To prevent this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers also have special encryption on their key fobs, which are not decoded by a simple program. These types of cars will need to be programmed by a professional, and you should only try this only if you've worked with electronic devices. It's a good idea to read your car's owner manual or look up the manufacturer online, as the steps differ based on vehicle type.
Transponder chips
Car keys with transponder chips require special programming to function. Any hardware store can offer you a new car key but the real challenge lies in implementing it to your vehicle. A key that has been reprogrammed will need to be compatible with the specific identification number of the vehicle or else it won't be able to start the engine.
Transponder chips, used to protect cars from theft, are a common feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signal when the key is put in the ignition. The car can detect the signal and begins the engine only if the signal matches the one programmed in the vehicle. The car also shuts down if a frequency is not valid. This makes it much harder for car thieves with no experience to connect a vehicle with hot wires and start it.
A circuit board equipped with an induction coil that connects the chip to the key. When the key is placed in the ignition it creates a magnetic field created around the transponder. This generates a signal that gets amplified by the coil which transmits it to the key's identification number. The key's identification code is returned to the car, and the engine starts if the identification number matches.
There are many ways to program a transponder, however all of them require a special tool. You can buy these tools online or at most locksmiths for cars. They're not cheap, but they're vital for programming the chip into your car.
You could also use a unreprogrammable key that was programmed for an alternative vehicle. In this case, make sure that the key hasn't been damaged or the transponder is not altered in any way. To check this, you'll need scanners or a computer equipped with an USB port to identify the chip and establish its identity.
The process of reprogramming a transponder key is quite easy, but it will require special software and a scanning tool. If you're new to the process it is recommended to seek help from an auto locksmith. Don't buy used keys since they may already be programmed and will not work with your car.
