How do you reset the alarm in a 1999 discovery land rover?

To reset the alarm in a 1999 Land Rover Discovery, you typically need to unlock the vehicle using the remote key fob or the key itself. If the alarm is still active, insert the key into the ignition and turn it to the "ON" position without starting the engine, then turn it back to "OFF." This process may reset the alarm system. If the alarm continues to go off, consult the owner's manual for specific instructions or consider disconnecting the battery briefly to reset the system.
