Cisa Lever lock Breakdown

[fgarci03]

Since no one replied my questions on my other post, I disassembled the lock and looked for answers (as I should have done in the begining, I was just afraid to wreck the lock )

So here's my steps:

• https://www.dropbox.com/s/7zojec36qteliz6/2013-02-08%2018.13.55.jpg - piece by piece disassembling
• https://www.dropbox.com/s/5vttsypun1lt44i/2013-02-08%2018.14.39.jpg - piece by piece disassembling
• https://www.dropbox.com/s/bk25d9tj7vbld6c/2013-02-08%2018.15.16.jpg - piece by piece disassembling
• https://www.dropbox.com/s/60rd2x7m9cdcnv6/2013-02-08%2018.15.46.jpg - don't know the name of this, but it's the piece that makes the bolt retract when the lock is unlocked
• https://www.dropbox.com/s/0n9uz7eeoaljtjn/2013-02-08%2018.16.36.jpg - first layer of (3) levers
• https://www.dropbox.com/s/u1vf6yld3jn6ihe/2013-02-08%2018.17.10.jpg - the bolt (on top of the other (3 lever) layer
• https://www.dropbox.com/s/de57zz650mk0742/2013-02-08%2018.17.32.jpg - the second layer of levers
• https://www.dropbox.com/s/ezo3v7z4dkawjo4/2013-02-08%2018.18.01.jpg - all 6 levers and bolt
• https://www.dropbox.com/s/yoe4z0jgvzdsi2b/2013-02-08%2018.18.07.jpg - the emptied lock
• https://www.dropbox.com/s/1gdn8xzxnxin4fu/2013-02-08%2018.18.21.jpg - the levers (can you notice the numbers in each one? Thank god they have them, I mixed them up when doing this )

So now I know it can be picked with a couple of wires

So I have a new question! The top and bottom bittings on the key (don't worry, this lock is not and will not be in use again) aren't simetrical. So it means the levers are cut so that one side of the key unlocks the lock, and the other locks it. So there is a chance to make a key that can only lock it, but not unlock it. Am I correct?

And if I look at the key again it shows that the right and the left side are, in fact, simetrical. So that means that despite having 6 levers, each one has another exactly the same at the other side of the bolt right?
Is that intentional? I mean, is it to have a shortcut in key making, or by having another lever with the same heigh may difficult finding the binding lever?

I also noticed that this lock has no anti-picking notches, but I couldn't pick it by overlifting the levers. Is that just lack of touch or this lock features something else in security?


Next project: Replace the back of the lock with a clear material, and cut on the front of the lock a hole where the levers are. By other words, make this a cutaway and also remove all parts that aren't needed so that it's much easier to add or take levers (like the Ultimate Challenge Practice Lock). When I find the time to do it, I'll post a "How-To".

Be safe!

It doesn't seem to me that this lock is suitable for the open area. It really looks like a safe lock to me.
I'm not a mod though so the decision is not up to me and so I might get that it's none of my business either. Maybe you should report it yourself so that the mods can see that you meant no harm.

So back to the business: I really liked you post, I think the pics are nice and your lock is a nice one. The lever locks I've seen mostly had a different way of being spring biased.
Judging by the pics I can't think of a reason why it wouldn't it be packable like other lever lock.

I think the numbers on the levers don't mean the sequence but the cut of the lever, at least it was so with the lever lock I took apart. So try reassembling and we will see what's up with that..

I think the top and bottom of the pins are different because the key is supposed to be turned more than once. That means in one turn you need to have cut side A up(and thus "controlled"), the other turn requires cut side B up. Although I think if you left one side blank the key will only let you turn it only once, but in any direction (closing and opening too). That means you could open the lock if it was only locked in one turn but not if, while locking, the key was turned more than once.
But that's just a theory I don't have the means to test it.

If this thread stays, could you write the exact name of the lock and/or lock family's name so that this post will be better searchable?


(PS: on a personal note: wow, this will be my 100th post. YAY! I wanted to do sth. special, so well don't take it as my hundredth post take it as a 99+1, and I will try and do a simple lock's breakdown on my "officially" 100th (in reality probably hundredandsomthingth). )

Hey!
First of all, thank you for spendind you 99+1 post with mine!

It doesn't seem to me that this lock is suitable for the open area. It really looks like a safe lock to me.

It is a door lock! I have another one in one of the doors arround the house (in fact, it was replaced because my sister lost the key a couple of years ago, so by fear of someone being able to open the door, my folks changed it). https://www.dropbox.com/s/zamiatkg4aw6qmk/2013-02-08%2022.51.50.jpg - Here's the one in use!
But I see your point and followed your advice. Thank you for that!

I think the top and bottom of the pins are different because the key is supposed to be turned more than once.(....)

DANG! I didn't see things that way but it makes much sense! (Feeling sooooo DUMB )


About the name. I really don't know. All I have is a box with a bunch of numbers (here and here). I don't know the model of the lock and I was expecting someone could tell me

I think the numbers on the levers don't mean the sequence but the cut of the lever, at least it was so with the lever lock I took apart. So try reassembling and we will see what's up with that..

Nope. The numbers are, in fact, the order of assembly. (When I read this I ran to the lock to see if the key still worked, as I hadn't tested it after re-assembly )

Thank you for your insights!

Be safe!
