All you need to know about locks and picking them

Keso 2000 Foil Picking


About a year ago I had a great meeting with Toools members from Holland and we even made a video together .

In the video I demonstrate a very cool dimple foil pick :

Lately I’ve decided to try more dimple locks with the foil method and I’ve had some good results(and some bad..)

The big  problem with dimple foil is that  in some key ways  it will tear the foil and it will be very hard to introduce a key that the foil won’t bend at some positions,also a deep cut near a low-cut can cause a problem.

The first lock I tested was a Keso 2000 ,this lock can be impressioned and picked but it would be very hard on a real door ,a simple solution is needed in here.

I  first tried to use a Keso blank to try foil but that didn’t work as the foil failed to enter the key way.I then tried some different blanks and different cutting of the key and found out that I can use a smaller shape blank and use a few layers of foils on a key meaning that if the first foil layer isn’t working after a few seconds then a second or even a third layer will open the lock.

 Here is a video of the Keso foil picking

I have 6 other Keso locks which ALL of them were opened in a very short time ,this tells me that this method of using a smaller key is working .

Also I stand correct Keso are made in Switzerland and not in Italy.

This is  the key after the picking

I’m currently working on some other locks like Kaba etc. I will keep you posted.

    Sorry for my bad english.
    I want to know what kind of key you use to make the impressioning. You wrote you have to take a smaller key than the real one.
    I buy some blank keys, and the brand is keyline ( is written on it), do you think those can work?
    last question: how do you make yourr cut on your blank key?

    Thank you

      Hello there Nimido and don’t worry about your English as it’s probably better than mine..

      I use an old Kaba key which is I believe is a Slica blank KAB3.

      I use a cut to code machine and and a keyway king machine to make the blanks.

        Hello Raf,

        I tried your method many times on a keso omega and it worked fine, but for my last try, the key was blocked at a quater of a turn. It’s like one of the pins fall in a hole it doesn’t belong to! Any ideas to fix the problem?

        Thank’s a lot.

        Hello Nimido.

        If the key won’t come out you will need to take the plug out and rebuild the lock.

        Try tapping the key first

    Hi Raf,

    Great ideas but why didn’t you show latest model keso omega on foil princip. It will be more interesting for everyone. All this is ancient history like keso 2000 and dom ix 5 or 10 pin. Looking so many sites like your, to many talk and work about braking history mits. Please, refresh air, I beleave in you.
    After all, keep up with good work, and please understand me. I am sooo frustrated watching stupidity on line specialy video clips.

    Best regards and good luck!

      Hello there Nitro.

      I can only write and deal with locks I have , it’s true that the Keso and Dom are relatively old locks but they are still out there.

      I’ve yet to see the Keso Omega lock but pls understand that not all locks can be viewed or picked.

      I will do my best to get my hands on this Keso lock and let you know

    Hi, how did you get the hole in the blank ? I mean, normally a blank looks not like yours. Which machine did you use to make the blank like yours ?

    What about the KESO 2000S-System with indented dimples? Is it vulnerable, too?

    I tried your system with an blank keso . I make the cuts just like you except on the mobile part (the omega system) which seems to be same for every lock. I built my own omega system within the key ( a micro spring+ a micro cylinder). The omega part work fine unexpectedly but the rest of the pins doesn’t ! Any sugestions?
    Thank you for your site!
