Hi, my front door handle plate has come loose but I can't remove the handle / plate to tighten the screws. The handles have grub screws which I have removed but the handle is still very firmly stuck to the shaft. The face plates have no visible screws but do have a black plastic end cap top and bottom. It is possible to lever these caps up/down a little but not enough to release the face plate, anyway the handles would still prevent the plate being removed. Do I need to be more brutal and prize the handle off the shaft or there some trick to this. The lock is a union monarch aluminium with a euro cylinder.
Thanks for any replies.
