You can reprogram key fobs yourself but you must be aware of the proper procedure. For the best results you should have the following items:

Keys

Most modern vehicles require a transponder key or fob in order to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with the car's systems and specific model. They are expensive to replace in the event of loss, so you should have spares in your car. You can also find replacement key fobs in various online stores and in many brick-and-mortar auto shops. But how can you tell that the key fob you bought is genuine? Can you tell if it has been programmed for another car keys reprogramming or if it could be reprogrammed for yours?

To program a new car key you must first verify that your vehicle is operating. Insert the key that you want to reprogramme into the ignition, but don't turn it. There are only a couple of seconds before the car's system reverts the commands and exits programming mode. For this reason, it is essential to move fast and not pause between steps. To avoid this happening, shut off the engine. You can test the system of your car by turning the key to the "on" position and then back to the "off" position. You should hear a chime signalling that the procedure was successful. The door locks will cycle.

Certain newer vehicles have rolling key technology that prevents thieves from using a stolen vehicle's key to start it. This technology is still vulnerable to a method known as replay attack which allows thieves to record the signal of the vehicle's key fob and then replicate it to unlock the car. To stop this, manufacturers have added a security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.

Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by an easy program. These types of vehicles will need to be programmed by a professional, and you should only try this only if you've worked with electronic devices.

Transponder chips

Car keys with transponder chips require special programming to function. While any hardware store can cut a new key for you, the biggest challenge is making it function to work with the specific car you own. A key that has been reprogrammed will need to be compatible with the specific identification number of your car or else it won't be able to start the engine.

Transponder chips, which are used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit that transmits a radio frequency signal when the key is placed in the ignition. The car then scans for the signal and starts the engine if it matches the original signal that was programmed into the vehicle. The vehicle is also programmed to shut down if it detects an invalid frequency. 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 linked by the circuit board which includes an induction coil. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that gets absorbed by the coil, which transmits it to the key's identification number. The key's identification code is sent back to the car, and the engine starts if the identification number matches.

There are several ways to program a transponder, however all of them require the use of a specific tool. These tools are available online or from most automotive locksmiths. They are not cheap, but they are crucial for programming the chip into your vehicle.

You could also use a reprogrammable transponder key that was previously programmed for a different vehicle. In this scenario, ensure that the key isn't damaged or the transponder has not been altered in any way. You can read the chip with a scanner, or a computer with the USB connector.

Reprogramming an transponder's key is simple, however it requires specialized software and a scan tool. If you're just beginning it is recommended to seek the assistance of an auto locksmith. Avoid buying used keys because they might already be programmed, and they won't be compatible with your vehicle.
