A Brief History History Of Reprogramming Car Key
Reprogramming Car Keys
Transponder keys are said to be more secure for cars and harder to copy by thieves. However, a key may need to be reset when it becomes damaged or lost.
You can change the key fobs you own, but you must know the correct procedure. To get the best results, you should have 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 must be programmed to your specific car and its systems by a licensed locksmith or dealer. They can be costly to replace if lost therefore, you should have spares in your 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 authentic? Can you tell whether it has been programmed for another car or if it can be reprogrammed for yours?
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 reprogramme into the ignition, but don't turn it. There are just a few minutes before the system will reset all commands and exits the programming mode. It is crucial to move quickly and don't be patient between each step. Turn off the engine to stop this. Change the key from "on" to "off" to test the system. You should hear a chime to indicate that the process was successful. The door locks will go through a cycle.
Certain newer vehicles have rolling key system, which prevents thieves from using stolen cars' key to open it. This technology is still vulnerable to a technique known as a replay attack that allows thieves to record the signal from the key fob of the car and reproduce it later to unlock the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers employ a specific encryption on their keys that cannot be decoded by a simple program. You should only try this method if you have experience is in electronic devices. Check the manual of your car or look up the website of the manufacturer for information on how to program it. The steps are different depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require special reprogramming in order to work. While any hardware store can cut a new key for you, the main problem is to make it work in conjunction with your particular car. The key must be programmed to match the exact identification number of your car, or else it will not start.
Transponder chips, used to prevent car theft, are a common feature of modern cars. The chip is a tiny microcircuit that transmits a radio-frequency signal when the ignition key is placed. G28 detects the signal and starts the engine if it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves who are not experienced to hot wire a vehicle and start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This creates a signal which is taken up by the coil and then transmitted to the key identification number. The key's identification number is sent back to the car, and the engine starts if the identification number matches.
There are many ways to program a key transponder, however each requires a special tool. You can buy these tools online or from most automotive locksmiths. They're not cheap, but they are essential for programming the chip into your vehicle.
You may also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this scenario, you'll need to make sure that the key has not been damaged or the transponder has been altered in any way. To check this, you can use a scanner or a computer with a USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but requires specialized software. It also requires an scanner tool. It's best to ask an auto locksmith for help for those who are new to the process. Avoid buying used keys because they could already be programmed and won't work with your vehicle.

In the past the time when car owners wanted to replace their key fob had to visit an agent to have it electronically paired with the vehicle.
