    They are simply worn.

    Don't bother digging the chisel out of the tool box, just find out whether
    it's the handles or latch that's worn and change the offending item - or
    both handles and latch if you wish.

    I investigated a worn latch like this just a few days ago. The wear
    was where the 'rotating bit' sits in the 'fixed bit' if you see what I
    mean. It doesn't have proper bearings, there's just a round hole in
    the metalwork of the innards where the 'rotating bit' through which
    the square shaft for the handle runs. The round hole was far from
    round after many years of door opening. There's not a lot one can do
    to repair it and I guess they're not very expensive anyway.

    Also the square hole in the handle and in the innards becomes a sloppy fit
    causing the handle not to fully retract the catch. Don't touch the striker -
    it is innocent!

    Buy new catch sets and possibly handles - grease well when assembling to
    reduce wear in the future

    It'll be the mortice latch mechanism which has worn. They are made of
    piss poor cast metal and not lubricated during manufacture.

    Screwfix sells them very cheaply and cheaper still in 10 off
    quantities, also the sheds have them.

    Unfortunately at some time in the recent past they went from Imperial
    to Metric, they look the same but by golly they're not the same so
    most probably you'll still need to get it out (your chisel, that is)
    so best do them all whilst you're at it.

    Generally the problem doesn't result in people getting stuck behind a
    locked door, but a similar problem on a bathroom lockset has resulted
    in people getting locked in the loo three times here.

    Aha. I wondered why some just don't quite fit - that makes perfect sense.

    Be careful as you unscrew the handles, and again when you're removing
    the latch. Often, a pile of oily metal filings drops out, and it's
    a real bugger to get them out of a light coloured carpet. Slide a
    piece of newspaper under the door to protect any flooring from this.
