Keys
Most modern vehicles require some kind of transponder key or fob in order to operate, providing security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to work with your car's system and the specific model. It's costly to replace them if they're lost, so it's a good idea to keep extras on hand. You can find replacement key fobs in online stores as well as numerous brick-and-mortar auto shops. How can you be sure that the key you purchased is genuine? Do you know whether the unit is programmed to work with another vehicle or if it could be programmed differently?
If you want to program an entirely new key first, you need to ensure that your vehicle is running. Insert the key you wish to program into the ignition without turning it. There are only a few seconds before the car's system reverts the commands and exits programming mode. It is important that you move quickly and do not be patient between each step. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. You should hear a sound indicating that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to keep thieves from using stolen keys to start the car. This feature is still vulnerable to a technique known as replay attack. It allows thieves to record and later reproduce the signal from the key fob of the vehicle to unlock the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to prevent hacking.
Certain manufacturers have a unique encryption on their keys that cannot be decoded using an easy program. You should only try this method if you have experience is in electronics. It is a good idea to read the owner's manual of your vehicle or look up the manufacturer on the internet, since the steps will differ depending on the car model.
Transponder chips
Car keys that feature transponder chips need special reconfiguration to work. While any hardware store can cut a new key for you, the real challenge is making it function with your specific car. A reprogrammed key will need to be compatible with the exact identification number of your car, or it won't start the engine.
Transponder chips, which are used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is inserted into the ignition. The car is able to detect the signal and begins the engine only if the signal matches the original one that was programmed in the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then turn it on.
The chip and the key are linked by an electronic circuit board that contains an induction coil. When the key is placed in the ignition it creates a magnetic field created around the transponder. This creates a signal which is taken up by the coil and sent to the key's 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 an instrument that is specifically designed for. These tools can be purchased through the internet or from many automotive locksmiths. They are not cheap, but they're crucial for programming the chip into your car.
You may also use a reprogrammable key that was previously programmed for another vehicle. In this scenario you'll need to make sure that the key isn't damaged or the transponder been altered in any way. To do this, you can use scanners or computers with an USB port to read the chip and determine its identity.
Reprogramming an transponder is a simple procedure, but it requires specialized software. It also requires the use of a scanner. If you're just beginning, it's best to seek out the help of an auto locksmith. Avoid buying used keys because they might already be programmed and will not work with your vehicle.
