Looking for some info

[Marek]

Hey, db got me into this hobby. And so I wanted more locks to play with, he gave me a schlage to practice on, but I didn't want to have to repin it all the time... I went through my house, and found a Zeiss Ikon 5 pin lock, it looks like it has some neat feature by the looks of the key. I was just hoping someone could give me some more information on the lock if possible.


Here are some photos!

It looks like it will have a sidebar or pin/s that need to pushed out to turn the plug, i would sugest doing those last after picking the normal pins.

I think they are now owned by Abloy as Zeiss seem to concentrate on optic manufacture.

I think they are also sold under the Ruko name and are common in masterkey systems.

The sides of the key do interact with a pinstack set on each side if I recal correctly. One pin one each side is either pushed into a groove and locks the cylinder or is allowed to be pushed in by the groove during rotation if the correct key profile is used. The second pin system on each side is a pin stack that has to be lifted to the correct position to again allow the plug to rotate.

Is this a common lock?

Not common in the US, but likely to be around somewhat in Europe. Your lock looks slightly different than mine judging from the keys. Your lock appears to have only a single pin or pin stack on each side of the plug.

Zeis makes a good quality lock, even with only 5 pins it can be a challenge. They also make 6 and 7 pin cylinders based on the same keyway. The company left the N/A market several years ago so I don't see many of these anymore.
If you rotate the plug , after picking, only a few degrees you will not have to deal with the side pins.
It is a good find have fun with it.

I thought that the strange keyway was somekind of copy protection. Without the right blank key the lock would only turn a little bit.
Those kind of locks are common in the Netherlands.

When you hand pick this lock and it gets blocked, you can just use a rake or so to "unblock" it. Just move the pick over the pins on the side.

Am i right ??

That is correct

This is an older system of Zeiss Ikon (indeed now owned by Assa Abloy), and it's hard to find any info about it anymore.

The marketing name was "Sperr Rippen Profil" - a profile with ribs that can block the cylinder.

A German description can be found here:
