You can change the key fobs you own however, you must be aware of the correct process. You should have these items to ensure the most effective results:
Keys
Modern cars require a transponder key in order to operate. This provides security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to work with your car's systems and specific model. They are expensive to replace if lost, so it is recommended to keep spare keys in the car. You will also find replacement key fobs at various online stores and in many brick-and mortar auto shops. But how can you tell that the new one you purchased is genuine? Are you able to tell if the unit has been programmed to work with a different vehicle or if yours can be programmed differently?
To program a new car key you must first ensure that your vehicle is running. Insert the key you wish to program into the ignition without turning it. You only have a few seconds before the car's system resets the commands and exits programming mode. Therefore, it is crucial to move quickly and not wait between steps. 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 signalling that the procedure was successful. The door locks will be able to cycle.
Certain newer vehicles have rolling key technology that stops thieves from using a stolen vehicle's key to open it. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and then duplicate the signal generated by the car key fob to unlock the car. To prevent this, manufacturers added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys that can't be decoded with an easy program. These types of vehicles require programming by a professional. Therefore, you should only attempt this procedure if you have experience working with electronic devices. It is recommended to consult the owner's manual for your car or look up the manufacturer online, as these steps vary by car model.
Transponder chips
Transponder chip car keys require special reprogramming in order to work. While any hardware store can cut a new key for you, the biggest issue is how to integrate it in conjunction with your particular car. The key needs to be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips, which are used to protect cars from theft, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is put in the ignition. The car then scans for the signal and then starts the engine if it is in line with the original signal that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it harder for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This generates a signal, which is taken up by the coil before being sent to the key's identification number. The ID number of the key is transmitted back to the vehicle and if it matches, the engine will begin to run.
There are a few different methods to program a transponder key but they all involve using a special tool. These tools can be bought online or from most automotive locksmiths. These tools aren't inexpensive, but they are vital to program your car's chip.
You could also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this scenario, you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. You can read the chip using a scanner, or a computer equipped with an USB connector.
Reprogramming an transponder's key is simple, but it requires specialized software and a scan tool. It is recommended to contact an auto locksmith for help in case you're not an expert. Also, avoid buying second-hand keys, since they're probably already programmed and won't work with your vehicle.
