I snapped one in a fastener quite a few years back, hence my earlier comment. The rest of the set immediately went in the bin once I realised there was no way back from there.

Thanks for the responses so far. I think I will try the Torx bit method and see if I can shift it that way, failing that, given that I can easily remove the handles both sides I may go for the nuclear option and try lock snapping.

I am sure there will be a 'helpful' video somewhere on line that will explain the process, but I will reserve that for 'when everything else fails' because at least as thing are the door is still secure using the original lock. If I try snapping and that for some reason doesn't work then I will have nowhere else to turn but to 'get someone in'

Have to say, the drilling a few mm into the centre of the screw head using a ~2mm bit is a neat addition, Grumpy.

Rubble, don't WALLOP the bit in, but give it a series of firm blows, making sure the bit doesn't shift position each time. The screw head is malleable - as you've proven - so it should form quite nicely around the bit.

Also, the blows will hopefully help to break whatever seal is making it awkward.

Yup, don't forget that just on the other side of the stile there are two large (=expensive) panes of glass, which are providing much of the rigidity of the door and therefore resistance to the [gentle hammer taps].

Thanks everyone for your help. Special mention to @Section62 and @grumpy_codger The Torx bit solution did the trick. One to remember for the future

Great result! 😁

You can give the new screw a smear of grease, and nip it up firmly, but not 😜

Yes. Another great solution filed away in the memory. Thanks to both.

It worked for me for £8, cheap solution. Not everyone has a tool to grind a slot in the head.

I had exactly this problem on my (2 year old) conservatory outer slave door after I moved in last year. My brother loaned me his Aldi screw extractors. The srew was far too soft to hold any torque.

My solution: tapping a nice sharp centre punch downwards from the 9 o'clock position loosened it.
