405 Phase 2 rear door lock removal

[bumperman]

As title really......
My 93 405 STDT estate(great old car!) is suffering from seized central locking on NSR door.
I've removed grab handle, door card, speaker, membrane, outer handle bolt, plastic cover, 3x lock screws etc, but although loose I can't seem to detach lock from door - any tips please? Haynes is pretty useless!

thanks

Sorry lads, but I was working against the bright light of the sun & couldn't see inside the door properly...........
I've now got it out of the door!

thanks
