Reprogramming Car Keys
Transponders in car keys are believed to make vehicles more secure and more difficult for thieves to duplicate. However, a key might need to be reset in the event that it is damaged or lost.
You can change the key fobs you own, but you must know the proper procedure. For the best results you should have the following items:
Keys
Most modern cars require a transponder key in order to operate. This provides security and protection against theft. The keys must be programmed to your particular vehicle and its features by an authorized dealer or locksmith. They can be costly to replace if lost and you should keep extras handy. You can find key fobs that can be replaced in online stores and many brick and mortar auto shops. How can you ensure 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 want to program a new key first, you need to ensure that your vehicle is running. Insert the key you wish to reprogram into the ignition, but do not turn it. There are only a few seconds before the system will reset all commands and leaves the programming mode. It is essential to move quickly and don't be patient between each step. To avoid this happening, shut off the engine. Change 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 go through a cycle.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the vehicle. This technology is still vulnerable to a method known as a replay attack that allows thieves to record the signal of the key fob on the vehicle and reproduce it later to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to prevent hacking attempts.
Certain manufacturers have a unique encryption on their keys that cannot be decoded by an easy program. It is best to only attempt this process if your experiences are with electronics. Consult your car's manual or visit the website of the manufacturer for information on 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. While any hardware store can cut a new key for you, the main problem is to make it work to work with the specific car you own. A key that has been reprogrammed will need to be compatible with the exact identification number of your car, or it won't start the engine.
Transponder chips, used to protect cars from theft are a standard feature of modern automobiles. The chip is a microcircuit which transmits a radio frequency signal when the key is placed into the ignition. The car then recognizes the signal and then starts the engine if it matches the original one that was programmed into the vehicle. The car also shuts down if a frequency is invalid. This makes it much harder for novice car thieves to connect a vehicle with hot wires and start it.
The chip and the key are connected via an electronic circuit board that contains an induction coil. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This creates a signal that is absorbed by the coil, which transmits it to the key's identification number. The key's identification code is returned to the car, and the engine starts when the identification number matches.
There are a few different ways to program a transponder key, but they all involve using an appropriate tool. You can buy these tools on the internet or at many locksmiths for cars. These tools are not inexpensive, but they are vital to program your car's chip.
You may also utilize a transponder that is reprogrammable that has been previously programmed for a different vehicle. In this scenario you'll need to make sure that the key has not been damaged or that the transponder has been altered in any way. To accomplish this, you can use scanners or a computer equipped with an USB port to identify the chip and establish its identity.
Reprogramming an transponder's key is simple, however it requires specialized software and a scan tool. It's best to ask an auto locksmith for help in case you're not an expert. Avoid buying used keys as they might already be programmed and will not work with your vehicle.
EZ Installer
Until recently, car owners who wanted to replace their key fob were forced to go to an agent to have it digitally paired to the vehicle.
