Strange lockpick problem

[Sindbadd]

Yesterday I was trying to lockpick lock in my house for like 2 hours and I could not open it. The best thing that happened is that after 1 hour of trying the lock turned a little bit and then stopped .. The lock is not very sophisticated , it is made by LOB company , simple 5 pin cylinder , not rusty or anything so I'm sure i don't need WD-40 or anything similiar... I don't know what could be the problem.. when I have the lock not mounted in the door I can open it without any problems , and when it is mounted in the doors it will not move .. maybe I'm doing something wrong , but I don't have such problems with lockpicking padlocks.. so i Have no idea what am i doing wrong..

Thanks for any help

I'm assuming this is a deadbolt.

When the lock is out of the door could you pick it in both directions, by turning it left and right? Some locks are easier to pick in one direction than the other and I'm thinking you may be going the opposite direction of how you were picking it out of the door.

Is the door closed while you are trying to pick it? Could the bolt be in a bind?

It can only turn one way when I use the key
Yes , the door is closed when I am trying to pick it
What do you mean by "Could the bolt be in a bind? "
By the way I never successed in picking a lock which is mounted to doors and I don't know why , I tryied many and always have problems.. i can only open locks when they are not mounted , there must be something I am doing wrong and i have no idea what :/

Where are you located? (Euro cylinders for example have a clutch that might cause problems).

Maybe even better: Show a picture of the lock, or give a link to a picture of a similar lock somewhere on the internet.

i am located in poland
for example im having prob with this lock



If i have problem lockpicking such lock with lockpicks , would it be simple to open it with a manual snap gun?

And what do you mean by "they have a clutch that might cause problems" ?

Thanks and regards

With "clutch" I mean a mechanism in Euro-cylinders that is required if you can insert a key from both sides (of the door). If both plugs in such cylinders had a fixed connection, you couldn't turn them unless keys were inserted on both sides. The clutch basically disengages the 'other side'; but when picking, one could potentially forget to activate that mechanism.

Most probably not applicable for your lock.

Now, to solve your problem (you can pick the lock when it's not mounted, but you cannot pick it when mounted):
Tell us the differences between these two states (not mounted and mounted)

Are there any? Do you remove the cylinder only, or the whole lock? Do you hold it in the same orientation?

[Sindbadd]

Hmm im doing everything in the same way mostly , I don't see any difference when I try to open it unmounted and when mounted...
When trying to open it unmounted i'm just having the cylinders , not the whole lock...

Maybe I have to use more wrench strength or something ? but i also tried that and nothing works

How does the cylinder interface with the lock body?
Can you pick the cylinder, turn it only a few degrees, then insert it into the lock body? Can you then move the deadbolt by turning the wrench?

Trying that, you might find out what's going wrong.

Sometimes when the lock is fitted tight to the keep, the tension on the catch/bolt is such that it takes a greater force to disengage it than that required to rotate the lock in the vice with a tensioner. Try picking the lock until it "jumps" then insert a suitable screwdriver into the keyway and turn it gently to see if the barrel will continue to rotate.

If there is a cam type mechanism inside the lock you would have the same problems either in or out of the door and anyway, all that would happen is that the barrel wil continue to spin without picking up the cam.
