ABUS Panzerriegel lock

We have an Abus Panzerriegel lock on our front door, i don't know the english name for these additional "across the door" heavy-duty bolt locks, but it looks kinda like this:

My question: How to remove the cylinder? On the outside of the door the cylinder part is circular (looks a bit liike this one, the inner part is dimensioned like a regular europrofile.

There is no way to remove the plastic cap on the inside (black in the pic on the Abus site) that I have found. The outside is obviously also free of any kind of manipulation points like screws or something.

Now, how to remove this thing? I will put up some pictures of the lock tomorrow, I have borrowed my cam right now unfortunately. But maybe some lockie around here can give an answer right away.

These locks take (long) Euro cylinders. Even though the outside part is in a round enclosure.
Euro cylinders are always held in place by the one screw; to reach that you will have to remove the cover of the whole thing (aluminum color in the picture). Should be possible from the side.

Cheers,

Thanks to mh, I got it. Iw as looking like stupid for screws, your hint made me check the beam cover on the inside and it is clipped on to reveal the long-wanted screws I can screw with.

Shrub, right about that generally I suppose, not on this lock model though. In this one you unscrew 4 screws on the inside, on a kind of holding plate. This plate keeps the cylinder in (there is a little screw stub going through the regular cylinder hole under the clutch). When pulling out the cylinder with the plate you don't have to have the key, because the locking cam is embedded in two semicircular metal pieces that form a gear and drive the bolt when turning the lock with the key.

Thanks again.
