Need help identifying ASSA cylinder

[Admin]

Hi guys, I recently took over some office space where the old tenants left me a big pile of old lock cylinders that belonged to old doors that had been removed. They did not know that lock cylinders kan be reconfigured and decided they would just get new ones in their new office. Anyway, I now have a bunch of cylinders with no keys that I would like to use for something, perhaps creating a number of practice locks out of. Phase one though is trying to figure out what it is I'm holding in my hand. I will here post some pictures I took, sorry about the image quality, using my iPhone for this.

* The cylinders have 6 top pins and look almost identical apart for what seems to be 3 extra (smaller) pins parallell to the main ones. One of the cylinders lack these 3 pins, and the cylinders that have them seem to be of two different configurations.

* The front of the cylinders all say ASSA SCD, except for the one cylinder that lack the 3 bonus pins, that one only says ASSA

* The back of the cylinders have engraved text, but otherwise looks identical. The text is:
Cylinder 1: SEP4 (no bonus pins)
Cylinder 2: E
Cylinder 3: R
Cylinder 4: SEP3
Cylinder 5: S
Cylinder 6: HHGDEE
Cylinder 7: HHGDEE
Cylinder 8: HHGDEE

Would be very grateful for any input

Cheers,

Matti

Moi, Matti!
Assa cylinders are quite hard to pick, but many of us are up for the challenge.
If you could post a picture of the keyway, we might be able to tell if blanks are available so keys can be cut.
The three extra pins you asked about are hardened steel pins just to make drilling more difficult. Hence the "SCD" -Security Cylinder Drillprotected.
I´m not sure, but think the 6-pinners are Assa 600 series.
Nice score! Now get some easier locks to practice on, and you´ll be able to pick these in a year or five.
If you ever want to get rid of them, just shoot a PM. I´m in the capital area.

Moi! Although, my name is a bit decieving. I live in Stockholm and don't speak Finnish at all However, i do have have a client in Helsinki that I visit maybe once per year.

After going through a box of 100+ old keys I managed to find one that fit 4 of the cylinders (keyed the same way). The key says "ASSA Twin Combi". I stripped it and parts where flying everywhere .. took me 30min just to put it back together. Like you say, this is clearly not a beginners lock. There were 6 pins, none of them straight. They are all security pins, of different length, with different length on the driver pins (I assume to make it impossible to bump the lock?). Also, there are 5 side pins working agains a second ridge on the key.

In the end, I took out the side pins plus 5 of the 6 top pins. Figured I will build 4 locks with 1,2,3,4 pins to practice how these security pins feel like when you pick them.

The 3 smaller pins are hardened inserts, these these are there to make it harder to drill out the pins in the plug.

Hello,

I hope you got my email about the account, sorry for any inconvenience but we're glad you're here.

I used to talk to Jaakko (a member here) in broken Fin, here is the source of much of what I know:
