I have a UPVC multipoint locking mechanism outside door. My problem was that the locking mechanism was quite stiff to operate even with the door open. I have tried 3 in oil and it now seems a little better. Is it a good idea to take the whole multipoint locking mechanism off and give it a good clean up and then replace it?( as far as I know the door is quite old )

Even if you took it out there wouldn't be a great deal to lube, the main gearbox my be riveted shut and pre lubed at source, if not i certainly wouldn't taking the lid off. There are holes and slots you could try getting some more oil in, i prefer to use aerosol lithium grease readily available at B&Q or hardware stores, the solvet makes it runny allowing it to get into tight spots then evapourates leaving the grease and its not so thin as to just flow away like say WD40 would, i'd also oil the locking strip from behind
