The "security" message on your 1996 Land Rover Discovery radio typically indicates that the anti-theft system has been triggered, preventing the radio from functioning. This can happen if the radio was disconnected from power or if the vehicle's battery was replaced.

If you don't have the code, you may need professional assistance to reset the system.
You reset the factory alarm by unlocking the doors with a key or remote.
