Abloy Classic cylinder cutaway

by **Jaakko** » 3 May 2007 10:29

I got an old, not in use anymore lock from my girlfriends parents. It is an Abloy Classic cylinder and after fiddling around with it, I dismantled it, cleaned it with toothbrush and acetone and thought I'd make a cutaway from it

Hopefully I get a huge pile of these from a friend of mine soon, so I can make these cutaways for sale. In a way this post is a heads up for those cutaways, so stay tuned

The cutaway I already made is not a perfect, but it'll do fine for demonstration

All the pictures are around 50-80 kilobytes in size and 800*600px. Hope you all like 'em

Here is couple of nice overall pictures from my cutaway:

In this picture you can see the backside of the cylinder. Just below the upper threaded hole you can see the locking bar grooves end. Also visible is the clip that holds the inner cylinder in place.

Here is another view to the backside:

These pictures show the locks inner works, the round disks that rotate a maximum of 90 degrees when the key is turned. Between the disks are spacers, that stay in place all the time, so that the disks can rotate individually. The spacers are the slimmer ones

Also visible is the locking bar (silvery steel bar), the inner cylinder and my needle files marks:

Here is a picture series when I'm turning the key clockwise to open the lock. In the first picture the gates in the disks are all lined up properly after turning the key 90 degrees. This provides a groove for the locking bar to press into, allowing the lock to turn open. Also visible in pictures are the shallow false gates. The number of false gates per disk varies between 0 and 4.

These pictures show the disks bottoms when opening the lock. In the first picture you can see that the notches in the disks follow the pattern of the key: On the left those two notches side by side are the disks that provide the turning pressure from the key to the inner cylinder. The second picture shows all the disks lined up and in the third picture the lock is already opening.

These are the rest of the picture series. If you spot something you don't understand or something I haven't explained, please post about it

As a sidenote, these pictures look like an advertisement shots

Actually, it will come on display whenever I find my needle nose pliers, so that I can get that freaking clip of the back...

Put me on the list !!!

Excellent! Cylinder locks are rather interesting, Ill have to buy a few on ebay soon and tear them apart. Nice clean cutaway and multiple pictures of just about everything, good stuff.

by **JackNco** » 3 May 2007 12:04

You can put my name on that list as well

Thats a really good job. looks like a nice simple cutaway to make as well.

by **Jaakko** » 3 May 2007 12:05

Ha! Found those pliers

Now, on to the pictures. By the way, all the pictures are taken with Canon PowerShot A70 digital pocket camera (3.2Mpx) in front of a two mirrors on a white wooden table with a little table lamp on the right side of the camera

I didn't have multiple light sources, so I improvised with those mirrors and white table

That little clip that holds everything together:
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00004.jpg

Next we find a very thin washer. This sits between the previous clip and the inner cylinder.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00005.jpg

The locking bars bend is visible. Also the groove can be seen where the locking clip normally sits.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00007.jpg

Pulling out the inner cylinder. In the picture you'll see the inner cylinders former shape at the locking bars end. As can be seen, I have cut the inner cylinder open from the middle almost fully.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00009.jpg

The inner cylinder pulled out. Notice the topmost disk: It has no notch like the others. This is a clever way to hamper drilling attempts

http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00011.jpg

The outer cylinder or shell (not sure about the terminology). Notice the left-sloping groove at the top.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00012.jpg

The inner cylinder with all the disks in place and the locking bar resting on top of those.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00014.jpg

The first disk and one of the spacers. The wide bottom of the spacer sits in the inner cylinder at the same radius as the notches in the rotating disks. This wide bottom keeps the spacers from moving while the key is turned. Also notice the sloped cut in the disk. This slope helps the locking bar to jump out of the groove formed by the disks, when the lock is being locked. And as the pictured disk is the first disk, it has the cut made so that it has to be turned 90 degrees always.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00016.jpg

The two holes in the inner cylinder. The shallow hole occupies that little (and only) spring and the one above that occupies the locking bars little end.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00017.jpg

The locking bar and the not-so-necessary spring. The spring helps the locking bar to disengage from the groove when the lock is closed and to extent prevents the locking bars little end from jamming inside its hole. The locking bar is round-edged steel bar. There has been a V-shaped cut made and then bent the bar to make it L-shaped. This form prevents the locking bar from being pulled out in the event of drilling a hole to the front of the lock.
http://koti.mbnet.fi/einstein/lp101/Abloy-cylinder/guts/00018.jpg

Close-up on the various parts of the lock. Notice the differing disk: It has some odd rectangular hole cut in to it, just between the code-cut and the keyhole. This is the last disk in the pack and I haven't figured why it is like that. If someone knows better, please let me know

Also on few disks can be seen the little hole drilled at the center of the disk. This prevents a certain type of picktool from working.

Enjoy!

Thank you all for listening and I hope that this tickles the minds of those who don't yet have an Abloy lock of any kind nor don't have an access to one

do you have details on what the lock was from?

Yep

The lock is from my girlfriends parents house, from the front door to be exact. A relative of my girlfriend was "a little drunk" once and ripped the door open when it was locked. The door was a double-door and with quite a gap between the doors, so the pull was able to bend the locking mechanism enough to break it and the lock had to be replaced because of that.

I actually have the backplate of the said locking mechanism and handful of other things that dropped from the door when pulled open

Gf's parents gave me the damaged locks parts and wished me luck. Well, lucky me, the lock cylinder itself was very intact, obviously

...until it met my bench grinder, needle file set and couple hours of time

I think I try t take a picture from the remains of the locking mechanism. If I got my terminology correct, it was a rim lock.

What was found from the floor and the door while installing the new lock:

(the moving shadow in the last two pics is my cat)

As you see, the pull damagd the backplate of the lock. Its supposed to be flat, but instead it has an almost 90 degree bend at the end

oh so THATS how u bypass them.

But keep us posted on them. i may have a couple off you, one as a cut away and one not if you selling them at the right price.

by **Jaakko** » 3 May 2007 13:16

Lets be more precise: The thing I made a cutaway from is an Abloy lock cylinder from a surface mounted locking mechanism. Pretty standard around here, especially in houss built 80-90's.

by **NKT** » 3 May 2007 14:38

Interesting. Not a shape that I've seen before. Kind of like a rim cylinder, only rather less diameter at the face. UK rim cylinders have a 32mm face diameter, and that looks a lot smaller.

Uh-oh, John said the "B" word! Now we all need advanced access to continue the conversation!

by **JackNco** » 3 May 2007 15:01

hehe, i meant kicking the door in. i guess i shoudl have said DE

Well, there is a face plate for the lock cylinder. As can be seen from the remains pics, there is a shiny and round thing with a hole in it.

And for very good size reference: The key is made from 6mm OD rod cut in half. The face of the cylinder is 19mm and the screwholes at the back are exactly an inch away from each other.

How are we to afford the bill for enough alcohol to keep a drunk Finn at hand whenever we need to open an abloy.

That is the reason these are called high security locks
