Yesterday I changed the handle on my front door and the lock etc. was left in place and something strange has happened!!! Before if I push closed the front door (without the key), the door could not be opened from the outside unless you had a key. Now however, unless the door has been locked with a key, the door can be opened from the outside just using the handle. Not sure what I’ve done here, any ideas??? Pics below of my new handle (still has to be fully screwed) - the old handle had a thumb lock where I have coloured the bit in red…this simply used to force the latch to stay completely in its recess so the door could be pushed open without any latch engagement…I’ve shown pics of the old thumb lock too… PS Sorry wasn’t sure which forum to put this into, so mods please do move if incorrect.
