You can change the programming of your key fobs at home, however you need to know the right process. You should have these items to get the best results:
Keys
Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. These keys are programmed by a locksmith or authorized dealer to work with your car's systems and the specific model. It is expensive to replace them if they become lost, so it's better to have spares available. You will also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. But how do you know that the new one you have bought is genuine? Are you able to tell if the unit has been programmed to work with a different vehicle or if it could be programmed again?
If you want to program an entirely new key first, you need to ensure that your vehicle is running. Insert the key you want to reprogram into the ignition without turning it. You only have a few seconds before the car's system reverts the commands and leaves programming mode. It is crucial to be quick and don't delay between each step. Turn off the engine to prevent this. Switch the key from "on" to "off" to test the system. There should be a chime indicating that the process was successful. The door locks will cycle.
Certain newer vehicles have rolling key system, which stops thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique known as a replay attack that allows thieves to record the signal from the vehicle's key fob and reproduce it later to unlock the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to thwart attacks on hacking.
Certain manufacturers employ a specific encryption on their keys that cannot be decoded using a simple program. These kinds of cars will need to be programmed by a professional, and you should only attempt this procedure only if you've worked with electronics. Consult your car's manual or visit 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. Any hardware store can give you a new car key, but the real challenge is in integrating it with your car. A key that has been reprogrammed will need to be matched with the specific identification number of your car, or it won't start the engine.
Transponder chips are a typical feature in modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car is able to detect the signal and starts the engine only if it matches the original that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it much more difficult for car thieves with no experience to wire a vehicle and start it.
The key and the chip are linked by an electronic circuit board that contains an induction coil. When the key is put 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's identification. The ID number of the key is then sent back to the vehicle and if it is in line with the engine will start.
There are a few different ways to program a transponder key however, they all require a special tool. These tools are available on the internet or at most auto locksmiths. They're not cheap, but they are vital for programming the chip in your vehicle.
You may also use a reprogrammable key that was previously programmed for another vehicle. In this case, make sure that the key has not been damaged or the transponder has not been altered in any way. To accomplish this, you'll need scanners or a computer equipped with a USB port to read the chip and determine its identity.
Reprogramming a transponder is a simple procedure, but requires specialized software. It also requires the use of a scanner. If you're a beginner it is recommended to seek the assistance of an auto locksmith. Avoid buying used keys as they may already be programmed, and they won't work with your vehicle.
