Keys

Modern cars require a transponder key in order to operate. This gives security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and the specific model. It is expensive to replace them if they are lost, so it's better to have spares in your possession. You can locate key fobs to replace them in online stores and many brick and mortar auto shops. How can you know that the one you bought is genuine? Can you tell if it has been programmed to work with another vehicle or if it is able to be reprogrammed for yours?

If you want to program an entirely new key, the first step is to make sure that your car is running. Insert the key you wish to program into the ignition, but do not turn it. You will only have a couple of seconds before the car's system reverts the commands and leaves programming mode. For this reason, it is important to move fast and not wait between steps. To prevent this from happening, turn off the engine. You can check the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should 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 car. The technology is still susceptible to a technique known as replay attack that allows thieves to record the signal from the key fob of the car, then reproduce it to unlock the car. To stop this, manufacturers have added an additional security feature known as the CAN bus protocol to thwart hacking attempts.

Some manufacturers also use special encryption on their key fobs which cannot be decoded by an ordinary program. You should only attempt this method if your previous experience is with electronics. It is a good idea to refer to 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

Transponder chip car keys require special reprogramming in order to work. While any hardware store can cut a new key for you, the biggest problem is to make it work with your specific car. The key has to be programmed to match the exact identification number on your car, otherwise it won't start.

Transponder chips are a common feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted in the ignition. The car detects the signal and begins the engine only if it matches the one programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it difficult for thieves who aren't experienced to hot-wire a vehicle and then turn it on.

A circuit board equipped with an induction coil that connects the key to the chip. When the key is put in the ignition, a magnetic field is created around the transponder. This creates a signal which is received by the coil before being sent to the key identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will start.

There are a variety of ways to program a key transponder, however each requires the use of a specific tool. These tools are available through the internet or from many automotive locksmiths. They're not cheap, but they're crucial for programming the chip in your car.

You could also use a unreprogrammable key that was programmed for another vehicle. In this case you'll need to make sure that the key isn't damaged or the transponder been altered in any way. To check this, you'll need scanners or a computer equipped with an USB port to read the chip and determine its identity.

Reprogramming an transponder is a simple procedure, but requires special software. It also requires the use of a scanner. If you're just beginning it is recommended to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they are likely already programmed and won't be compatible with your car.
