2000 VW Beetle The anti theft alarm does not disable when I unlock the door. How do I disable the alarm system?

To disable the anti-theft alarm on a 2000 VW Beetle, try unlocking the driver's side door with the key rather than using the remote. If that doesn't work, insert the key into the ignition and turn it to the "on" position without starting the engine; this can sometimes reset the alarm. If the alarm still doesn't disable, consult the owner's manual for specific instructions or consider disconnecting the battery briefly to reset the system. If problems persist, visiting a professional mechanic or a Volkswagen dealership may be necessary.
