    I have an Ingersoll lock, about six years old, that has become loose. It can now be opened just by pushing on the door. If I let the door swing closed, the lock tends to just bounce out rather than locking. There's nothing visibly wrong with the lock, but something must have become misplaced. Any idea how I fix this? There are two small screws above and below the mechanism that look as if they are used for some sort of adjustment - maybe I need to adjust them?

    Thanks.

    Here you go. Not sure that they show much except that there's a screw missing. The lock was purchased new.

    the staple (keep) on the frame doesn't look right. it is a very poor fit and is not pushing on the deadlocking feeler above the bolt. That has to be pushed in to lock the door.

    has it been altered, or is it an electric release or something?

    show us more of it.

    Nothing has been altered recently, I just noticed it starting to be a problem a couple of weeks ago. It's not an electric release or anything. You'll see in the photo that there's some sort of security fitting around the staple so this makes it harder to reposition it.

    Try moving the latch hold back device. That is the rotating piece on the very left hand side of your photo. It will move upwards.
    The two screws you refer to are holding the backset on to is mount on the door.

    Yes it does move upwards but all that does is hold the lock on the latch so it won't lock at all, surely?

    the staple looks rather old to me.

    the gap between the door and the frame is far too big. In this picture,
    the door does not look as if it is fully closed into the frame.

    If the staple was correctly fitted so it was close to the fore-end of the lock, then it would press that feeler button in when the door was shut, which deadlocks the bolt. Press it in with your thumb and you will see what I mean.

    The feeler is telling the lock that the door is open, so it is not properly locked.

    I suppose you could pack out the the staple with a strip of hardwood or something. but it does need to be firmly fixed to the doorframe and/or wall to resist attack.

    If it has recently got worse it might be that weather conditions have made the door and/or frame warp or shrink away from each other so that the gap has got bigger.

    There is a good picture of the SC71 here http://www.discountlocks.co.uk/Inge...clid=COjajND5u7UCFYfJtAod1hEAOA#axzz2L6fi2Qgw

    I think that what has happened is that a lot of the plaster behind the staple has fallen away, causing the staple to fall in on the right hand side of the photo of the staple. The staple is old but I don't see anything wrong with it, it's just what it's sitting on that is the problem. I'll try filling the gap in with polyfilla unless you think it's important to use hardwood.

    you have an expensive lock to keep burglars out.

    Polyfilla is useless. I would scrape the frame clean and fit a long hardwood strip, glued and screwed, and remake the fixing holes for the staple. While you're at it ensure the frame is screwed and plugged firmly to the wall.
