Well, that was a fiddle!  I've two locks on my flat door, when I go out I only ever lock the bottom mortice lock so I only carry that key; the top lock is a cylinder lock outside with a hand turn knob inside ... I use that when I'm in the flat so I can always get out the door without needing a key (A lesson I learned from my fire!).

So I get home today and the top lock is ... locked! 😱

(Not sure why ... one cannot open the top handle if it is locked so it wasn't that ... I can only imagine when I left this morning I was drowsy and unthinkingly turned the knob on the way out ... or it somehow locked itself when I pulled the door too!)

Call to my local friend who has a spare set ... I never gave her a top lock key.

Brief attempt to McGuyver it open using a paperclip ... not surprisingly unsuccessful.

Phoned my landlady who lives about 30min drive away ... who happened to be just around the corner, popped into estate agent to get spare keys and then let me in ... PHEW!!!

Lesson learned ... NEVER going out again without BOTH keys!
