lever lock pressure

[ridderhenck]

I started today with lever locks,I have read the theory about lever lockpicking.And now I have a question:

1.Howmuch pressure is needed to lift the levers?

unfortunately I think your going to find this under the dreaded (ADVANCED TOPIC). I dont know for sure though. I would love to help but ill let the admins make a ruling first.

Howmuch pressure is needed to lift the levers?

its going to depend on the spring pressure of the levers and how much tension your using.
greater tension is going to bind each lever more.

[Shrub]

Hmm strange question that is, you either lift the lever or not,

The question woulkd make more sence if you asked how much tension do you put on the lock which the answer would be a lot compared to pin lock picking,

As for tension on the levers well the best i can suggest is when you turn the key on a new unfitted lock you are lifting 5 of them so reduce that by about 5,

But as i say a bit of a strange one that,

What pick you useing and what lock you playing with?


Lever lock picking is totaly fine in the public sections, there are no restrictions on that,
The restriction as regards lever locks comes as tools to open them other than simple picks and this also includes any type of decodeing them like P+C etc,
Hope this helps?

Thanks for the info Shrub,it helps a bit,


I am busy with a wire experiment that,s why I wanted to know the pressure level so I can decide which sort of wire I can use without bending the wire ,makes sense?

[Wolfe]

gotcha,
In that case what kind of lever lock is it?
General Rule:
the amount of tension is reilitive to the combined force of the tension bolt and sping on each lever. Its usually a little more than the amount of torque used on a pin tumbler.BUT needs to be slightly adjusted as each lever is set, but to remain constaint like in a pin tumbler as to not loose each lever that has been set.
hope this helps

Thanks !!

I am going to take a look on the insides tommorrow,I,ll let you know then!!!!


As for picks,I made picks from spokes,anyone other materialsuggestions???

[Shrub]

Piano wire all the way, i dont and never have liked bike spokes as they are too soft for lever picking to any degree of useage,

Go to your local model shop and grab some piano wire, you wont regret it and the levers will lift on a new lock way before you bend it

As for picks,I made picks from spokes,anyone other materialsuggestions???

i made mine from high tensile fencing wire, its cheap and very effective.

I,m working with guitarstrings at the moment,pianowire is on the way but these guitarstrings,baseguitar to be precise,work fine.but thanks for the tip,to try is to know whether it works for me or not,

Goodmorning,It,s been a while but that,s because I,ve been busy building stuff,but back to the subject,I,ve bought a two lever lock and I,m trying to make equipment to make life and opening this lock easier!!Enough ideas on this site

I wonder whatever happened with some of the ideas mentioned earlier on,like the 5 wire idea,the antenna idea????

[Shrub]

They didnt work basically,

[ridderhenck]

sorry to hear,back to the drawing table

[ridderhenck]

I,ve been thinking about the 5 wire idea,what were the problems why it didn,t work?

I have this thought that another idea might work with one wire,using a tube with a rod for tension and a second tube slided over the first one with a small hole drilled at the end so a stiff metal wire can take the levers one by one to the right level,you can turn the second tube from left to right and back and forth,also change the height of the wire in order to find the right level for the levers.

This is too much to go into detail here and also on the public sections,

You have a very small area to get wire with enough srength into the lock,

Times that wire by 5 and add a tension wire or tool and your pushing it,

These locks have so many other tried and tested methods of opening them it has to be somthing special to not use the commercial tools or home made copies rather than somthing else,

I agree that all things come from ideas but i really really dont have time or inclanation to fully explain and describe the workigns of a lever lock to help you understand why it wouldnt work,

If you dont have any lever locks get some and play with them, you will soon see for yourself how 6 wires strong enough to throw the bolt and lift levers in a keyhole is nearing on pointless and thats forgetting the fact that you lose feedback when the wires are rubbing on other wires,

Trust me when i say ive tried somthign and that it doest work, i tried the 5 wires thing 3 or 4 years ago now and with locks getting better not worse i assume its still a no goer,


You can only set one lever at a time anyway so why have 5 wires? use one wire and lift each lever individualy which will make a faster opening, less complicated tol, stronger tool, easier to use tool, more efective tool etc etc,

If your worried about getting under levers you can use an indicator pick like mark fransis sells,

Dont also forget that in somthing like a curtained lock the low levers require the picking wire to be moved around quite a lot to manipulate them which a fixed shaft driven one can not do,


As regards tools made from car ariels theres simply no strength there for them to work properly,
