EVVA 3KS

Here is a nice review of the 3KS and how it works:
(this is a direct copy of what is on my website and can be found along with other locks @ http://www.locksmitharmy.com/locks.php)


The EVVA 3KS has 3 sidebar like things that interact with the housing. 2 are true sidebars that contact the housing and 6 slider pins each, and the third contacts the top of the key which has a number of angled cuts in it.

3KS KEYS.JPG

The keys have 3 sidewinder lines cut in each side, each line is a different depth. It also has a V shape cut at the tip. The V cut catches all the sliders and forces them into a chanel where they are slit along the sidewinder cuts based on depth and number of pins, which you will read about next. The keys also interact the sidebard on the side at the enlongated notch just before the bow of the key.

3KS SLIDERS.JPG

Next, the sliders, contact the key and the sidebars. On one side are round pins that interact with the key, and the other side has notches which interact with the sidebar. You may notice some sliders have 2 pins and others only have one. Now look back at the key. you may notice 2 of the 3 lines are exactly the same, these 2 lines dont go as far into the key as the 3rd line. So the double sliders go in the 2 lines that are alike, and the single sliders dont go in either of those lines because they are to long to fit, so they are pushed all the way to the center of the V cut and enter the 3rd "unique" line.

3KS SIDEBARS.JPG

Now we get to the sidebars themselves. The 2 outer sidebars (on the outside of the image) have 2 springs each and a large tab to the front which goes through the plug and into the key and a small tab which also goes into the plug. The part of these 2 sidebars that contact the pins are the 2 lines that are above and below the springs. These 2 lines sink into the 2 cuts in each slider pin. The 3rd sidebar sits ontop of the key and it has angled cuts that match the angled cuts on top of the key. When picking this is not a bother because if the wrong key is inserted this sidebar will be pushed up into the housing, if NO key is inserted, the sidebar is not pushed up at all, so it is ignored.

3KS PLUG.JPG

You can see in the plug, at the very top, is the sop sidebar, just to the side of that are 6 holes for 6 slider pins, there are 6 holes on the other side aswell. These 12 holes go all the way through the lock so the slider pins can extrude to the top or bottom of the plug and into the housing, and it will still turn (you will see in the next paragraph). On the median of the plug is a large slot for 1 sidebar, on the other side is the same slot, you can see the spot for the 2 tabs to sink in to keep the sidebar straight, and the front slot goes all the way through so the sidebar can contact the key.

3KS HOUSING.JPG

Lastly the housing.The housing has slots for all the sidebars and slots for all the slider pins to extrude. This means, as stated before, that the pins can extrude from the plug and the lock still work, this makes taking the lock apart a pain.

Because I have to many pictures and not enough words, I will explain how to take this lock apart if you have one. On the tailpiece there is a little cover that is held in by a roll pin, this pin needs to be knocked out, I used a 1/16in drill bit and it fit perfectly, hit it with some pliars I had handy and it popped right out(easier than expected). Then the circlip that is on every lock, no big deal. Now to finally remove the plug you need to get all the sliders pulled into the lock, so hitting it on one side should knock the sliders to that side... then slide a shim in the other side. Then knock the lock on the side that the shim is in and it will push all the sliders aginst the shim, and the plug will slide out. The key is not necessary.

Now to the fun part, to pick this lock you need a long thin prod to raise and lower each slider pin, tension is applied normally and the top sidebar is ignored. I have not picked this lock with all its sliders in it, but I am getting there.

May be a stupid question but is it pickable? Great pictures and explanation.

Re: EVVA 3KS

that's a pretty intense looking lock man...so you manipulate the sliders like you would the pins?
Naaapaalm...sticks to kids...it sticks to the belly and it sticks to the ribs...
See those kids standing by the lake...drop some napalm and watch them bake.

Re: EVVA 3KS

bouncer, the post above urs has a picture of a picked one bro

you simply raise and lower the sliders with any probe, I made one from a small wiper insert and I put a dimple in the tip. I have seen people use hooks to do it

Re: EVVA 3KS

Yet, the question remains "Is it pickable?"!

I've just spent 2 days on this lock and was happy to find this site. Unfortunately the above picture is clearly a fake!
The lock in the picture has the outer sidebars removed. In a picked lock you would see the ends of the sidebars, 'grabbing the key' at the front end of the keyway.

So, as I am no pro-picker myself... I am very interested to know if anyone has actually picked one of these. I would be very interested to know how that would have been done - via PM of course
And please don't mention the decoder, unless you are able to send me a picture of it, together with a detailed description on how it works ;)

Re: EVVA 3KS

http://lockwiki.com/index.php/File:Lockpicking_EVVA_3KS_picked.jpg
here is another one for ur viewing pleasure

AND what do you mean dont mention the decoder unless you can provide a picture and description... are you skeptical of its existance or someting...


the images in this pdf are the only images I have of the decoder without taking screenshots of the VIDEO I have of falle describing and using the tool... If ur that interested in it purchase the gov edition of LSS+ and it will have the video (aswell as many many more videos)

and that is not a faked image... the sidebars have had their prongs grinded down so it wouldnt grab my pick when it opened... (this was done in an attempt to not grab my pick, which turned out to be useless when i actually got one picked as the sidebars dont protrude enough to actually grab the pick, unless u have a stupid thick one)

Ill work on another pick for ya (as soon as i dig out my 3ks, im moving now and its in a box...) I have a second 3ks that is unmodified so the prongs will be visable.

and there is no need to pm info on this lock... its not restriceted to super advanced forums here

just feel it out man, one slider at a time... work up from lower security slider locks first then try to tackle this one...

Re: EVVA 3KS

Thanks for the quick reply!
The second picture is little more convincing - unfortunately - as you can not see into the keyway... so you can not see the 'pins'. But then I guess no picture is fake-proof...
Though I am also a skeptic to some degree, my colleague is very hard to convince when it comes to photo-evidence...

Working for the government, I wish we had the LSS+ gov. edition, but I guess Germany is too poor for that. There is one copy I know of, but I can't really wait for ages, having it mailed here, with this.
- Which doesn't mean I am not interested in the pictures you offered..! I am always trying to expand my horizon :)

And thanks a lot for the pictures of the decoder! I will have to sit down tomorrow and work out how it might work :) Just hard to find some pics of it on the internet. Got me a little frustrated today...

How long would it take you to pick this sort of lock? And (for me) most importantly, what type of pick would you use?

Re: EVVA 3KS

I work on these locks on a daily basis.
To take them apart , we have a special key from Evva. It has the slot for the long pins in the center of the key , and the parallel groove just around that. This keeps the pins in the center of the core , so we can take it out without trouble.

Here's a pic of 2 of these. It's a bit blurry , I know.
The one on top is for our profile of 3KS+
The lower one is for the normal 3KS , any profile.
