How Do I Take This Lock Apart?

[illusion]

Ok so as some of you will know this lock uses the Chubb AVA system and I'm sure most people can deduce that it is a bullet lock - Blah blah blah...

Basically, what I want to know is how I get the darn thing apart without cutting into it - although I have a feeling this might be the case...

Any ideas?

Got quite a nice photo of the keys:

most of your lock has a look of precise machining, but when you show the back of it, theres an area that does not apppear machined, while the pin that sticks through the back of the lock is machined.
perhaps this is machined out of a cast block and this is simply an un machined area, such as an engine block which is partly machined and the rest is just a cast metal finish.
however, lock makers use tricks to hide some things, like any snap ring fastener that would be on the back of so many locks.
so perhaps the internal core was assembled through the back of the lock and some method like press fitting or other such was used to cap that end and then disguised with some brass in epoxy mess or whatever.

I don't know that lock, but those are my thoughts.

Thank you for your thought Raimundo.

I'm not certain it is going to be possible to take this apart and reassemble afterwards without shed loads of work so I may have to give it a miss, it wasn't expensive at least and is quite a neat lock anyway.

Maybe a control key of some sort?

looking at it, the question arises, "how did they get the discs and spacers inside that tube.

when confronted with a brass pintumbler padlock,
you can ding the edge of the lock with a tiny jewelers ballpeen or even the round back of a spoon and when you hit one of the round brass covers over the drill holes that has been hidden by a brushed finish, the plugs will sink just a tiny bit further into the lock and leave a tell tale round mark of the drilled hole, of course you can see this with the eye if the plugs are made of a different brass than the lock body

I would look very closely at the outside of this lock to see if there are any hidden features like this.
