At the risk of being shunned for suggesting it, see if you can get a
quote from a locksmith. A friend of mine had the same problem last year
(except that he knew he had a key inside), I was thinking about forcing
his smallest window (upstairs PVC double glazed unit) but in parallel
googled for locksmiths. Turns out there is one less than a mile away, he
was out and then in the house within an hour, even though it was a
Sunday evening. For £80, which I thought was a bargain.
You'd be surprised ...
When I became old enough to warrant my own front door key, mum gave me a key
that my late father had found which fitted the lock, although it was not
exactly the same.
Later, my younger brother became eligible for his own key so I had an idea. I
bought a couple of key blanks, then took the lock off the door and dismantled
it so that we would know for sure exactly which key profile was needed. At
this point, all became clear ...
... When I was 5 months old, a German V1 exploded not far away, demolishing
an entire block of houses at right angles to the end of our street and
causing severe damage to all the other houses in the area. We were
temporarily rehoused while the repairs were carried out.
When we returned, my parents found ample evidence that, being in the middle
of a row of 15 houses, the builders had found it convenient to use our house
as a base & to store all their materials. We even knew which door they'd hung
their dartboard on!
To make it easy to come and go, the crafty beggars had removed all the
innards of the lock so that the key to any front door in the street could
I cut the blanks down to size and presented one to my brother. A little later
we replaced the old mortise lock with a Yale one ...
Yeah thanks Adam. FWIW, I waited 8 days until I gave up and destroyed the lock; it then took just a further 36 hours for the old key to appear.
On a top shelf in the garage - WTF? Can only have been put there by me but I have zero recollection.

OK so I was 33 hours out. But we both know that even if you had waited
18 months to destroy the lock the spare key would still have only turned
up 36 hours after you had destroyed the lock:-)
BTW when you were searching for the spare key did your other half ask
you "when was the last time you had/saw the spare key?"
I'm reminded a friend of mine made a key.
Since you have a second identical lock, make a key with a peg to make
contact with just a single lever.
By measuring the angle this key makes when the peg contacts the lever
you can work out the lever depth by comparing similar angles with the
If you do this for each lever you have a fighting chance of cutting down
a blank key to the right profile.
Thanks for all the advice.
On the back of this I'd basically decided, 'right, it's locksmith time',
and was quoted ?60 incl VAT, excl the new lock (which I would do myself).
But then I thought 'sod it', let's have a crack with the angle grinder
first and see what happens...
...so I did, and you know what, it worked like a dream! No damage to the
door or frame at all. Locksmith cancelled :)
