Change cylinder on Mottura lock

[juanm]

So, I just lost one of my apartment keys, and in case it was stolen instead of lost, I have to change the lock cylinder. I've changed quite a few smaller cylinders and locks over the years, but this one is from a security door, and I cannot access the cylinder retaining screw (labeled "2") from the side. I've been doing some research, and it seems to be a Mottura Champions C28 (not sure about the exact model) in a Series 85 Mottura Lock.

My instinct tells me the small screw on the left of the cylinder (labelled "1") might be the answer to my problem, but my experience -and my wife- tell me there's also a fair chance I'll end up making a small bolt fall inside the lock assembly, so I thought it would be better to ask the experts before.




Any ideas about how to get the cylinder out of there? Thanks!

Keep in mind that I am NOT a locksmith, but screw 2 holds the lock in the door. Fairly confident that screw 1 holds that cover in place (along with at least one other screw). If you remove the cover, you should be able to get a tool in and loosen the screw #2 to remove the lock towards you.

Might be a good idea to hear input from those who are locksmiths first, but that is what I would do.

Thanks. That's what I thought. It just looks like a cheap screw, not one that would hold in place one of the most important screws in the mechanism. If that's the case, I'm, well, screwed, because to take apart the whole front plate, I'm afraid I'd have to take apart the whole door (the wood is glued around).

I've done some more research, and in their catalogs, they mention the cylinder attachment method with the side T slot where Screw 2 goes, is called "Mottura Attacco" (in English, "Mottura attachment"). Does that sound familiar? I could, with some patience, dremel that screw to cut it and take the cylinder out, but to replace a new one I'd have to jury rig something, and I don't like that.

Thanks, that's it, yes. Do you think the only way to change the cylinder is to take off the whole cover plate?

una vez quitada la parte posterior del escudo
el cilindro sale hacia ti girando la llave hacia la posicion de la leva en vertical

no es necesario desmontar nada mas

after removal of the back of the shield
  the cylinder goes into turning the key to the position of the cam you vertically

is not necessary to remove any more

Muchas gracias!!

Thanks you all! In the end the insurance took care of it, and sadly I wasn't home when the repairman came to do it, so I guess I'll give it a try next time!
Cheers.
