So when I got to the job i had a good look at the lock which was fitted nice and tight, with no movement in the cylinder without the right key. At this point I was a bit sceptical about the guy opening the door with his key so the lady went over to the neighbour and asked him to try it again, he did and sure enough his key opened the ladys door




Upon further inspection of the 2 keys it turned out that from the shoulder of the guys key his 2nd 3rd 4th and 5th cuts where identicle to the 1st 2nd 3rd and 4th cuts of the ladys key and the 5th cut of the ladys key was equal to the leading edge of the guys yale key.
Now had I not seen it with my own eyes (and tried it myself more than once) I would never have believed that by putting this yale key into the lock and pulling it back one cut it would open the lock as it did.Surely this has got to be one of the strangest things I will ever come across in this job as I have often heard of lockies turning up to empty morice locks that will open with a screwdriver but come on, the guy across the hall having a near perfect copy of your key made by 2 different manufacturers thats almost x-files territory.
Has anybody else ever come across anything like this before or better still something stranger still.
