You can change the key fobs you own however, you must be aware of the correct process. For the best results, you'll need the following items:
Keys
Most modern cars require a transponder key in order to operate. This is a security feature and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. They are expensive to replace if lost and 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. How do you ensure that the one you purchased is genuine? Do you know whether it was programmed to work with another vehicle or if it could be reprogrammed to fit your vehicle?
To program a new car key first make sure that your car is running. Insert the key that you'd like to program into the ignition, but don't turn it. There are only a few seconds before the car's system resets the commands and exits programming mode. It is important that you move quickly and do not be patient between each step. Shut off the engine to prevent this. Turn 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 go through a cycle.
Certain cars with more modern technology have rolling key technology, which keeps thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique known as replay attacks that allows thieves to record the signal of the key fob on the vehicle and then replicate it to open the car. To prevent this, manufacturers have added security features known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys, which cannot be decoded using a simple program. It is best to only attempt this method if your previous experience is in electronic devices. Consult your car's manual or look up the website of the manufacturer to find out how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Car keys with transponder chips need 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 match the specific identification number of the vehicle otherwise it won't even start the engine.
Transponder chips, used to prevent car theft are a standard feature of modern automobiles. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is placed. The car then detects 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 incompatible frequency. This makes it more 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 placed in the ignition the magnetic field is created around the transponder. This generates a signal, which is taken up by the coil and then transmitted to the key's identification number. The key's ID number is sent back to the vehicle, and if it matches the engine will begin to run.
There are many ways to program a transponder, but each requires the use of a specific tool. These tools can be bought through the internet or from many automotive locksmiths. These tools are not cheap but are essential for programming the chip in your car.
You may also utilize a transponder that is reprogrammable that was previously programmed for a different vehicle. In this case you'll need sure that the key isn't damaged or the transponder been altered in any way. You can read the chip by using a scanner or a computer that has a USB connector.
The process of reprogramming an transponder's key is easy, but it will require specialized software and a scan tool. If you're just beginning, it's best to seek help from an auto locksmith. Don't buy used keys since they could already be programmed, and they won't work with your car.
