You can reprogram key fobs yourself, but you must know the correct process. You must have these things to ensure the most effective results:

Keys

Almost all modern cars require some kind of transponder key or fob to operate, providing security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's systems and specific model. It's expensive to replace them if they become lost, so it's best to have spares available. You can also find replacement keys fobs on various websites and in a variety of brick-and-mortar automotive shops. How do you ensure that the new one you purchased is authentic? Can you tell whether the unit has been programmed to work with a different vehicle, or if it can be reprogrammed?

To program a new car key you must first verify that your vehicle is operating. Insert the key you wish to program into the ignition without turning it. You will only have a couple of seconds before the car's system resets commands and leaves programming mode. For this reason, it is crucial to move fast and not be able to wait between steps. To prevent this from happening, turn off the engine. Switch the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime signalling that the process has been successful.

Some newer vehicles use rolling keys to keep thieves from using stolen keys to start the car. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and reproduce the signal received from the car key fob to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to prevent hacking attempts.

Some manufacturers also use special encryption on their key fobs, which are not decoded by an easy program. These types of vehicles require to be programmed by a professional, and you should only try this if you have experience working with electronic devices. It is recommended to read your car's owner manual or search for the manufacturer on the internet, since these steps vary by vehicle type.

Any hardware store can make you a new programmable car keys key, however the real challenge lies in integrating it with your car. The key needs to be programmed to match the exact identification number on your car, otherwise it won't be able to start.

Transponder chips are a typical feature of modern automobiles and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted in the ignition. The car is able to detect the signal and begins the engine only if it matches the original one that was programmed in the vehicle. The car also shuts down if a frequency is invalid. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then 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 an electromagnetic field around the transponder. This produces a signal which gets taken up by the coil, which then transmits it to key's identification number. The ID number of the key is sent back to the vehicle, and if it is in line with the engine will start.
