How do you reset the alarm on a 2001 range rover?

To reset the alarm on a 2001 Range Rover, first ensure that all doors, the hood, and the tailgate are securely closed. Then, insert the key into the ignition and turn it to the "ON" position without starting the engine. Wait for a few seconds, then turn the key back to the "OFF" position and remove it. This should reset the alarm system; if the alarm continues to trigger, consult the owner's manual for additional troubleshooting steps.
