Reprogramming Car Keys
Car keys with transponders are thought to keep cars more secure and are less likely to be duplicated by thieves. A key may have to be reprogrammed in event of damage or lost.
You can change the programming of your key fobs at home, however you should be aware of the proper procedure. For the best results you must have the following items:
Keys
Nearly all modern vehicles require some kind of transponder fob or transponder keys to operate, ensuring security and anti-theft protection. The keys have to be programmed to your specific vehicle and its systems by a licensed locksmith or dealer. They are costly to replace if lost, so you should have spares in your car. You can find key fobs that can be replaced in online stores, as well as many brick and mortar auto shops. How can you be sure that the one you bought is authentic? Can you tell whether it was programmed for another car or if it could be programmed to work with your car?
If you are planning to program an entirely new key first, you need to ensure that your vehicle is operating. Insert the key you wish to program into the ignition without turning it. You have only a few seconds left before the system resets all commands and exits the programming mode. It is crucial to move quickly and do not be patient between each step. Shut off the engine to prevent this. Switch the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful. The door locks will go through a cycle.
Some newer vehicles use rolling keys to keep thieves from using stolen keys to open the car. This technology is still vulnerable to a method known as replay attacks that allows thieves to record the signal from the key fob on the vehicle, then reproduce it to unlock the car. To stop this, manufacturers have introduced a security feature called CAN bus protocol to thwart hacking attempts.
Certain manufacturers also have special encryption on their key fobs, which are not decoded by an ordinary program. You should only try this method if you have experiences are with electronics. Check the manual of your car or visit the website of the manufacturer to find out how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Car keys with transponder chips need special reconfiguration to work. While any hardware store can cut keys for you, the real issue is how to integrate it in conjunction with your particular car. The key has to be programmed to match the exact identification number of your vehicle, or else it won't be able to start.
Transponder chips are a typical feature of modern automobiles and are designed to prevent car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is inserted into the ignition. The car then recognizes the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it much harder for car thieves with no experience to connect a vehicle with hot wires and then start it.
The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is generated around the transponder. This generates a signal that is taken up by the coil before being sent to the key's identification. The key's ID number is then sent back to the vehicle and if it matches, the engine will begin to run.
There are a variety of ways to program a key transponder, but each requires an instrument that is specifically designed for. You can buy these tools on the internet or at many locksmiths in the automotive industry. These tools aren't expensive, but they are essential for programming the chip in your car.
You may also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this instance you'll need to make sure that the key isn't damaged or that the transponder has been altered in any way. The chip can be read with a scanner, or a computer equipped with a USB connector.
The process of reprogramming an transponder's key is simple, however it requires special software and a scanning tool. It is best to consult an auto locksmith for assistance in case you're not an expert. Also, avoid buying second-hand keys, since they're likely to be programmed and won't work with your vehicle.

In the past, car owners who wanted to replace their key fob were forced to visit an authorized dealer to get it electronically paired with the vehicle.
