Well you were right jeff.
I have just talked to Brian Morland a locksmith from the UK and he told me that it actually is the Y52 keyway and key as you said. We both agreed that the keyway is nearly the same shape than the Y1 and that my locksmith probably was not wrong saying it is the Y1, both really look much alike (Y1+ being 5 pins and Y1 6 pins). He probably did not understand or recognise that people are also going to buy the blanks for it and that therefore Y1 is not correct and Y52 is correct. However Brian also stated that the Y11 is too big and not usable for the Commando Lock 5 pin core as it has a too large diameter.
AB62R is actually an ABUS blank, I have some Y5/Y52 blanks that also fit.
Y52 it is jeff I accept defeat and should have done better research.
I still do not like your attitude and the way you are talking about me and I will say that here in public as I have no problem with that. And as said before I said "restrictive" most of the time maybe except 1-2 times and have no idea why you got me wrong there. My first language is not English and I did not expect people to be that picky on that.
I honestly dont think anyone was talking "behind your back". It's a forum, we post here to interact with others in the hobby and promote discussion. From someone who speaks english as my first language I can tell you that Jeff was not being confrontational or disrespectful.
He knows what I mean. He is talking bad behind my back in an online chat.
