Key Fobs
Modern key fobs offer many conveniences and security benefits. They can be used to replace or enhance traditional car keys and can do more than just lock doors. They can also start the engine, activate alarms, and perform other functions.
The key fob communicates with the receiver in the vehicle using radio signals. When you press the button on the keyfob it transmits the code to the receiver which then does the job you want it to. Commercial building owners also make use of key fobs to connect them to a larger system of access control. They can track who is entering and leaving and also prevent fobs from being stolen or lost.

Some car manufacturers have an onboard program that is specifically designed for their vehicles, while others require you have an advanced programmer attached to the OBD2 connector.
The most commonly used method of programming new keys for cars is to insert the key fob into the ignition and turn it on in a specific order.

The computer then saves the code and then takes the car out of programming mode.
