Abloy Classic cutaway w/ pics

[dougfarre]

Just got this new Abloy Classic from Jaakko in Finland. Jaakko hand made this cutaway and it came out great. I figured i would share with everyone, because it is such an interesting lock. For those of us that have had little experience with Abloy's you should find this interesting. It wasn't until I actually took an Abloy apart, or looked at the cutaway, could I actually understand how the lock functioned. I could read Han Fey's articles all day, but still not have a clue how the lock worked. I really needed to get my hands on one to get a full understanding of how these things operated.

Considering we are not talking about picking, there is nothing advanced in this post. I am just showing you a few pictures. Here is where you go to learn more:

Here is a picture of the lock with the keyway visible and the keys off the the left.




This is a progression of the key going into the lock and turning the plug counter clockwise almost a full rotation.









As you can see, when you turn the key, all the little disks line up their grooves. This allows the side bar to retract into the plug, and allows the plug+cam to rotate!

Welcome to the world of Abloy
Be careful with these, they are addictive, next thing you'll do is spending all your money on the Protec drugs...

i agree with mh, stay away from Abloy once you start you can't turn back!

Abloy's are very sexy, and that is a beautiful cutaway. Jaakko did a great job, and you certainly have a nice lock on your hands.

And you are very correct in saying that it is so much easier to understand the working principle when you get to fiddle a cutaway lock I haven't yet got the time to disassemble the Disklock (Pro), but I'm getting there some day

Yea those things are so cool. I got one (not a cutaway) from Jaakko as well and spent like half an hour just putting the key in and turning it like a little kid. It found it amazing how simple they are to assemble and disassemble as well. You really get a feel of how nice the design is.

After the key lines up the disk notches and the sidebar drops in place, what rotates the plug? It seems that if the key continued to rotate the disks, the sidebar would just jump out of place again. Is there a part of the key that just rotates the plug the way the end of a lever lock key retracts the bolt?

And are those false notches on the disks?

[Trip Doctor]

Actually, after the sidebar drops, the key rotates the plug. So the first 90 degrees you spin the key, it lines up the wheels, after than, it rotates the plug. If you look at the gates/holes on the wheels, they're not symmetrical. One side has a slope that allows the sidebar to drop in and slide out. The other side slopes inward toward the hole and 'grabs' the sidebar. So when you keep spinning they key, the sidebar doesn't drop, it's spun with the plug, but when you spin the key back, the sidebar rides up the slope of the hole into its place.

There are false gates on the Abloy disks.

The disks in the classic keyway also have a stop/protrusion opposite the gate. When a 0 disk rotates a full 90 degrees, the stop hits the other side of a cut out on the plug and helps the plug to rotate, as long as the proper key is in there.

Disklock disks do not have the stop/protrusion opposite the gate and false gates. They work in conjunction with scrambling bars to turn the plug.
