I've been following the very well typed guide on the 'How to' section. I managed to get the passenger side off really easy. Ive removed everything on the drivers side now, come to pull the inner weight up and attempt to slide left whilst the Mrs was puling the handle, but there seems to be a plastic lug there to stop it coming out.. Is this something to do with keyless entry?
