This only lasts for only a few minutes before the car exits the programming mode.
Once your vehicle is in programming mode, you will need to repeat the process for each key you'd like to program. The instructions contained in the owner's manual must be specific to the type of key and model you're trying to program, since some models have additional security features that have to be enabled (for instance the passcode required to access certain programming modes).

Key Fobs
Modern key fobs come with numerous advantages in terms of security and convenience. They can be used to replace or augment traditional keys for cars and manage more than only locking doors. They can start the engine, activate the alarm and perform other functions.
The key fob communicates with the receiver in the vehicle via radio signals. When you press the button on the keyfob, it transmits the code to the receiver which then fulfills the function you desire. Commercial building owners also use key fobs as they allow them to integrate them with an entire system of access control. This lets them track who enters and exits, and also stop fobs that have been lost or stolen.
Like all electronic devices, key fobs can fail at times. They can break or lose their signal if they are lost in purses or pockets. Although they're built to withstand many things, they're not indestructible; after all, they're little more than metal and plastic.
