change the handle on the passender side, the arm that operates the lock mech will have either snapped off completely, or cracked(usually a commo prob with ECP and GSF handles) easy fix tbh,
as horney said with the brake lines and brake lights.
orange bulb for the indicators.
easy peasy.
and daniel, no that shouldnt fail i dont think, mine was fully de-locked at one point had its mot and it passed, so both passenger door and drivers door were de-locked. admittedly it had central locking and remote locking, but im sure the passenger side doesnt need to have a lock.
