Abus 75 50 EC 75

[Varminter]

Just found this neat Abus at the local mart and thought I would give it a try.

Anyone have a good idea for a tool I can make to pick this lock?
Tried to use a home-made half diamond to lift the pins with a sideways torquing but it wouldn't really fit in there.
By the biting it don't seem to be very hard to pick but it's just so tight and I suspect spools in there.

I don't know if there are spools used in dimple locks, the length of the full height of the pins is so short.

Who knows of security pins of any kind in a dimple lock, tell us, greyman?

that said, dimple locks do have security features that may trap driver pins and such, I have heard. someone else here may have much more knowlege of taking them apart, seeing the features etc.

[femurat]

I don't know about Abus, but ISEO R6 dimple lock do have spools... 4 spools out of 6 pins in chambers 1,3,4,6.



As a tool I suggest an half diamond, but you have to modify its tip. File a little groove on the tip to make it stable on the pin you are working on.

Here is a video of wizwazzle (if you don't know about him you have to see his videos) picking a dimple lock with a custom pick, I guess you are thinking of something along those lines.

So a half diamond just bend in a 90 degree angle to the right?

[femurat]

If you bend the picktip you can use it just on certain locks: left or right. If you just make a small valley on the tip, the pick becomes smaller and is free to move inside the keyway without the need to bend it. And most important is more versatile: it works both with left and right locks.



The pick in the middle is my favourite for dimple locks. This photo was taken before I sanded it, but I think you can see the tip.
It works very well with ISEO but also with both multlock left and right versions.

Great!

Will make one first thing in the morning and give it a try!

A slimline hook is sufficient for this lock.

Here's me picking the small version (5 active pins, 3 passive).



I've also picked the EC 950 Euro Cylinder with it, and that has 6 active pins and 4 passive pins (probably the same as your lock).
They are a nice challenge to pick.
Don't forget to put it on video once you've picked it

Nicely picked

But what is the deal about the passive pins? I'm really a noob regarding dimple locks.

[l0ckp1cker]

Nothing special.
They are meant to restrict key profiles, but for picking you can pretty much ignore them (just make sure your tension wrench isn't touching them.

If I remember correctly the EC 950 has mushrooms in it, but I would have to gut it again to be sure

[Varminter]

Have still not been able to pick the lock but I made a bump key and successfully bumped it
Still looking into how to make a dimple pick.

[femurat]

Making a dimple pick was an hard job for me too.
I tried using some different picks and I wasn't satisfied, so I made this pick.


As you can see it's an half diamond with the diamond longer than usual. This can help you to centre the pick on the pin.
On the working tip of the diamond I made a little groove with a round needle file: so your pick is self-centring on the pin.
Put it on the top of the pin and rotate it to push the pin down. For a good control I recommend a cylindrical handle.
With this pick you can concentrate on the pin manipulation without worrying about the pick position. This help a lot when you are dealing with security pins.

After a while I found myself able to pick a dimple lock even with a diamond or a hook, but that's another story.
I think a specific pick can help you a lot to learn how a lock works. Then you'll be able to pick it whit almost whatever pick you have.

here is a picture of the pins in the Abus EC750 europrofile zylinder....




I picked it today the first time and i find it very hard to pick,

The problem are not the pins, but the profile is very hard if you have pins that must get seted deep.....

tomorrow i post some pictures of my tools....

well femurat, I picked the R6 you sent me. coupla times, but Im not braggin that its easy, I found that I could get the false set very easily, but from there to open is not yet a certainty. When It comes, its sudden and very easy to turn. no hard pressure.

the keyway of this thing has excellent perches for the tensor on either end, the end that does not go through to the cylinder wall has a rectangle in the keyway profile that fits a tensor that is made of a piece of flat steel probably a bladed bicycle spoke or a piece of wiper stiffener. they are both similar, the spoke I am speaking of is rectangular in cross section not sharp edged.

The pick I am using I made for it. the warding is such that the approach to the pins from either side is at an angle perhaps 45 degrees accross the keyway. and the hook is inside this angled part of the keyway, where its easy to slip the hook tip alongside the pins and lift them with a twist,

once I get the false set which is very easy to do, lift all the pins together with a straight probe and it will false set immediatly, but then you have 4 spools hooked over the edge of the shearline, and from there its another matter to open it. Whats worked for me so far is luck and perseverance, but soon if I keep messin' with it, its gonna show me a secret, perhaps a binding order for the four spools

[femurat]

Hi Ray, I was waiting for this news

I found useful to use the left part of the keyway (the hole where you fit the tensor) for the pick. I have more space for the pick shaft to go up and down while I rotate it. The hard part is setting the shortest pin and having more space helps me a lot.

I fit the tensor in the right rectangular hole, not the last one otherwise it could bind against the cylinder wall. The second one starting from right.

About my technique... is the classic approach to spools pins. I go in and out a couple of times with my half diamond to get a false set. Easy. Then I start testing the pins one at a time, looking for counter rotation of the plug. If the pins are stuck I pass over, otherwise I set it. Basic, but you need to learn a feel for it.
If some pins are reset means I've overset one. If so I completely release tension and start again.

This lock taught me the importance of light tension. I think this is a lot harder than a 7 pins multlock. I hope you'll have a good time playing with it till you completely understand and manage it.

Cheers

Hello from Germany
I pick the EC 750 with the goso Dimple picks.
It goes very good with this tool.
I have bei Youtube a Video from the Ec 750
