You can reprogram your key fobs at home, but you should be aware of the proper procedure. To get the best results, you should have the following items:
Keys
Most modern vehicles require some kind of transponder fob or transponder keys to work, which provides security and protection against theft. These keys must be programmed to your specific car and its systems by a licensed dealer or locksmith. They are costly to replace if lost therefore, 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 can you know that the one you bought is authentic? Can you tell if it has been programmed for a different vehicle or if it is able to be reprogrammed for yours?
If you are planning to program an entirely new key, the first step is to ensure that your vehicle is operating. Insert the key you want to program into the ignition without turning it. There are only a couple of seconds before the car's system resets commands and leaves programming mode. It is important that you move quickly and don't delay between each step. To prevent this from happening, turn off the engine. You can test the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should be able to cycle, and you will hear a sound that indicates that the process was successful.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the vehicle. The technology is still susceptible to a method known as replay attack, which allows thieves to record the signal from the key fob on the vehicle and then replicate it to unlock the car. To stop this, manufacturers have introduced a security feature called the CAN bus protocol to prevent attacks on hacking.
Some manufacturers use a special encryption on their keys that cannot be decoded by an easy program. You should only try this process if your experiences are with electronics. It is a good idea to read the owner's manual of your vehicle or look up the manufacturer on the internet, since these steps vary by car model.
Transponder chips
Car keys with transponder chips require special reprogramming in order to function. Any hardware store can give you a new car key, but the real challenge is in integrating it with your vehicle. The key you reprogrammed needs to match the specific identification number of your car or else it won't be able to start the engine.
Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car then scans for the signal and starts the engine if it is in line with the original signal 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 then start it.
A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This produces a signal which is amplified by the coil which then transmits it to key's identification number. 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 several ways to program a transponder, but each requires an instrument that is specifically designed for. These tools are available through the internet or from many automotive locksmiths. These tools are not inexpensive, but they are vital for programming your car's chip.
You may also utilize a transponder that is reprogrammable that was previously programmed for a different vehicle. In this instance, you must ensure that the key isn't damaged or that the transponder has not been altered in any way. To accomplish this, you'll need scanners or computers equipped with an USB port to identify the chip and establish its identity.
Reprogramming a transponder is a simple procedure, but requires special software. It also requires a scanner tool. If you're a beginner you should seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they're probably already programmed and will not work with your car.
