GeGe cylinders

One has to learn to face his fears, so after I managed to open some old Guard cylinders (now EVVA G330/550) with nasty paracentric keyways, I decided to take a look at GeGe...

GeGe ANS2-6
This is a six pinner with very interesting element in the bottom of the keyway - it is a hard metal stop, that should work as an additional drilling protection. It also features a anti-bump protection (here pin 6), that is very similar to the one I encountered in the FAB 200 cylinder - the driver enters the cylinder only a tiny bit, so the pin sits quite low and usual bump key wouldn't touch it...
Other than that, there is a counter-milling in chambers 2-6, that makes the last few moments of picking quite frustrating. Thing to note is also the interesting shape of the security drivers - it is an interesting serrated/spool hybrid; also note the variety of driver lengths - I'd say it is another level of the anti-bump protection (not sure if it can make impressioning any harder).
And last, but not least - note the anti-drill keypin in chamber 1 and driver in chamber 2 - I'd expect them in the same chamber...

As far as picking is concerned, the key bitting isn't helping much, not to mention the keyway profile - 15 thousands and a selection of deep hooks is a must (at least for me - SSDev combined with Multipick) and to be honest, these locks made me switch picks like no other...
One thing I didn't managed to photograph are 2x5 holes on both sides of the lock body - they are most probably meant for passive pins in the master key systems; the lock I have didn't have any installed and the core had no holes them.

GeGe AP2000
This is a standard five pinner, that seems to be a newer incarnation of the ANS2 - event the key profile is the same (although the strange element in the bottom of the keyway prevents full insertion of the AP2000 to the ANS2 lock - the key "lip" is thinned on one side). This particular lock doesn't have any anti-drill protection at all, which is probably the reason why it is one level bellow the ANS2 securitywise.
The rest is more or less the same, just the anti-bump pin is in chamber 4 - that makes it stand out like a missing tooth, when you explore the keyway with pick the first time...

This one went first - one pin less helps quite a lot, when learning the feedback...

Next stop - pExtra+, probably a sixpinner...

GeGe pExtra+ SE-6
This is a grade 4 cylinder, six-pinner, with interestingly shaped keyway, that is meant to make creation of the blank very hard - the "Y" shaped protrusion aims to do that.

The internals are pretty similar to other GeGe locks - there are the serrated-spool hybrids, the last chamber features the anti-bump pin and the rest are standard drivers. Also the core is countermilled in chambers 2 to 6. The core also has a single chamber for a passive pin, the key has a dimple for it, but the pin itself is for some reason not present in this lock. The lock bible has five dimples on each side, so it is possible that there might be more than one passive pin, or the passive pin might be in different positions in different locks (for masterkeying purposes?). And last thing are the two steel inserts, that are protecting the sides of the core - they were free in their chambers and fell out of there when the core was turned pin side down (out of the lock, of course).

Pickingwise this lock was not that hard to pick - the keyway caused very little problems and also the tensioning (TOK) was much less of a problem. The bitting left only two pins where the serrations could cause a problem; the technique of trying to push a binding pin as far as it will go and looking for the last click allows for relatively quick "mapping" of the problematic pins. All this allowed for unexpectedly short fight this lock put up, compared to the ANS2-6.

What caught me by surprise was the way the lock was packaged - the lock, the keys and the screw were all wrapped in a plastic foam sheets; no scratches from keys on the lock, nothing rattling. So far I haven't seen a lock packaged in this way.
