easy-peasy...
You'll probably have to get new red tabs from vx, but they are pence.
basically:
a row of screws along the bottom,
one behind the cover on the door handle (interior one that is

)
two behind the other handle (the one that pulls the door, not opens it....)
take the door mirror cover off cos it'll help.
remove the red tab from the locking pin, it'll probably break.
and one screw behind that.
then pull!

make sure you don't break the clips that hold it all on, there's only a couple.
the plastic sheet behind needs to go back on so try not to split it - I think it's for condensation purposes.
