ZeissIkon padlock - complete breakdown and reassembly

[p1ckf1sh]

WARNING: Huge images ahead!

OK, this my favorite padlock at the moment, nice heavy duty in black, made by ZeissIkon. What I really love about is the removable cylinder system. The cylinder is almost the size of a half eurocylinder but not quite the same format. It rather looks like a snowman, if anyone knows the exact name of that specification letme know.

The cylinder used is a standard pin tumbler, 6 chambers, the profile looks a bit weird at first, but you actually have a LOT of room to move the pick because the centerline is basically not obstructed.

I'll just post the pictures now, it is all pretty self-explanatory.













I'll have to check if the recording of the reassembly (yes! motion picture!) worked out good enough to be presentable to a wider audience. You'll also get a video of me opening this thing (6 pins, 4 spools) in 30 secs or something. I don't know if anyone is interested in this at all, it's just a pin tumbler, nothing special, so...

As always, comments and question are welcome.

[p1ckf1sh]

Hmmmm. No replys, no interest in this? Should I post the reassembly videos anyways or is this is not of interest to you guys?

Oh, it's interesting.
I would have spammed this thread, but i'm busy with my homework at the moment.
Srry.

Nice picks though.

And yes, a vid is allways welcome.

Yeah, ditto. From the look of that padlock, it's been around a while. Is it something you can buy new currently in, say, a Baumarkt? If so, how much?

I have not seen anything like this around in stores, i suppose you have to special order them because demand is low. I got it from buddy of mine who is building tech in a hospital. When i first opened and disassembled it there were only five chambers pinned and it was full of wafer pins, enabling et least a dozen key bittings.

Here are the videos...

1. Reassembly of the shell - putting balls, cam, spring, shackle into place, showing function of the cam and interaction with the balls (kinda), also making clear why shimming won't open this lock. I snipped out the part of putting the springs and lower pins into the cylinder, I could not align my eyes and the camera to look into that small area at the same time, and it would have warped the 3min time limit of photobucket.


2. Pinning the cylinder plug, assembling the plug and cylinder shell and mounting the cylinder into the shell. Cylinder is pinned through all 6 chambers, spool pins in 1,3,4,6, regular pins in the rest.


3. Picking this one. Time from insertion of pick to open shackle is about 20 seconds.


Enjoy. Hope the photobucket system works out for everyone. It works wie IE and Firefox, can't say anything about Mac or *ix systems.

thanks a lot, great videos.

Nice pictures and video I wish all locks were as simple to disassemble and tinker with.

I was under the impression that security pins were very rarely used as the #1 spot... or am I counting wrong. Is #1 the closest to the keyway or furthest inside the lock?

Thanks,

Ah, I guess it doesn't matter (see above, since they are in 1 AND 6). One of those is closest to the keyhole.

These are not even the original pins. As said, the lock came with a config that made multiple keys work (5 or 6 wafers in different stacks), so I repinned to have some more fun. Originally it had... 2 or 3 security pins if I remember correctly. I just did not care where I put the sec pins, in the pic (and the vid) they are on the 1,2,5,6 positions, currently it is repinned to 1,3,4,6. As long as there is one regular pin the lock is stable (will not wobble etc.)

On a side note, due to the heavy spring force you could actually put security pins into all stacks and still have no issues when inserting the key, because the spring will turn oit back to 0° reliably.

On the security pin in chamber 1 question - I don't know about the locks you play with, but quite some euro-cylinders I have seen do this. BKS usually has 2 security pins in 1 and 2 and Abus even uses 4 out 5 pins security (type spool) and the last one (rear of the plug) is a serrated security pin. These manufacturers don't seem to have any issues about it.

i just got hold of one of these but its got Assa Ruko 2 stamed one it, it had a broken keyway in it but the locksmith cut a key from the code stamed on the side.

the core also looks like its got some kind of check in after the second from the front. its larger pin set to the side of the rest in between the second and third.

did u ever findout the spec/name of that format?

when i first saw the photo of the plug, I noticed that the last, deepest hole actually appears to be slightly smaller than the other five drillings, I have seen this in other plugs as well where only five pins were installed, and have wondered what this hole is for, do they only make one plug and sell two grades of lock, the 5 and the 6 pin, because the hole always appears slightly smaller, I have speculated that a pin may hold this first drilled hole while the gang drill comes in and does the other five at one time. if a plug slipped sideways at all during the beginning of the drilling, it could foul the machine and require new drill bits, so the plug is held against rotation by a pin in that 6th hole, (thats only a guess of course.) It would be great if someone on the forum worked in a lock assembly plant and knew this stuff, unfortunatly, talking to us may not be agood carreer move.

ill have to get some pick of this i think its got 9 holes in all

Thank you . I need all the help I can get identifying locks.
