Reprogramming Car Keys

Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. A key may have to be reprogrammed in the event that it is damaged or lost.

You can reprogram your key fobs at home, however you must know the right process. 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 anti-theft protection. These keys must be programmed to your specific vehicle and its features by an authorized locksmith or dealer. It's expensive to replace them if they're lost, so it's best to have spares available. You can also find replacement keys fobs at various online stores and in a variety of brick-and-mortar automotive shops. But how do you know that the new key fob you bought is genuine? Can you tell whether the unit has been programmed to work with another vehicle or if yours can be programmed differently?

If you are planning to program an entirely new key first, you need to ensure that your vehicle is on and running. Insert the key you want to reprogramme into the ignition, but do not turn it. You will only have just a few seconds before the car's system reverts the commands and then exits programming mode. This is why it is essential to be quick and not wait between steps. Stop the engine to avoid this. You can test 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 chime to indicate that the procedure was successful.

Some newer cars use a rolling key technology that keeps thieves from using a stolen car's key to open it. This feature is still vulnerable to a method known as replay attacks that allows thieves to record the signal of 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 stop hacking attempts.

Some manufacturers also use special encryption on their key fobs, that cannot be decoded with an ordinary program. You should only attempt this method if your previous experience is with electronics. Consult your car's manual or look up the website of the manufacturer to learn how to program it. The steps to follow will differ depending on the type of vehicle.

Transponder chips

Car keys that feature transponder chips require special reconfiguration to work. Any hardware store can make you an entirely new car key, but the real challenge is in integrating it with your vehicle. A key that has been reprogrammed will need to be compatible with the specific identification number of your car, or it won't start the engine.

Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car can detect the signal and begins the engine only if the signal is in line with the original that was programmed in the vehicle. The car also shuts down if a frequency is not valid. This makes it difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.

The key and the chip are connected by an electronic circuit board that contains an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal that gets amplified by the coil which sends it to the key's identification number. The key's ID number is sent back to the vehicle, and if it is in line with the engine will begin to run.

There are several methods to program a key transponder, but all require an instrument that is specifically designed for. These tools can be bought online or from most automotive locksmiths. They're not cheap, but they're crucial for programming the chip to your car.

You can also use an unreprogrammable key that was programmed for another vehicle. In this instance, you must make sure the key hasn't been damaged or that the transponder has not been altered in any way. You can read the chip with a scanner, or a computer equipped with a USB connector.

The process of reprogramming the transponder key is easy, but it will require an expertly designed software and scan tool. If you're just beginning you should seek the assistance of an auto locksmith. Avoid buying used keys because they may already be programmed and won't work with your vehicle.
