Problem with lock after disassembling

[Ilia]

I had trouble picking my 6127 Master Padlock because of the spool pins so I decided to open it to see how everything works. I removed the last 4 pins (I think key pins as when I moved my key I could see them moving up) however now when I enter the key into the cylinder it will not turn and I can't pick the lock either (which is quite strange because there are only two pins). I think the problem may be that I had left the second (driver pins?) and the springs in the lock.

I did a search as I didn't want to post a third question thread but most people wanted help with disassembling a lock and I couldn't find anyone with a similar problem.

Does it move at all? If it shifts in either direction but gets jammed, you may be right, you might have left one top spring in there by accident. This happens to me all the time. Usually I just take a offset screwdriver and turn it while pushing the plug out. But I'm sure this method can score the insides of the lock and if the plug is held in the housing by being staked at the back of the lock you might not be able to take the plug out unless you bend that area out of the way.

That's a tricky one.. You can force it out by lifting the dropped driver pins and picking the first two but you might wrap the springs around the cylinder if a driver is not lifted high enough.

Thanks very much for the replies. Yep I'm sure now that I have left the driver pins in there and with no key pins to set them on the sheer line. The lock isn't really of great value its more a question of wanting to know how to fix it then actually having to fix it.

The key does does move in either direction (only a tiny bit to each side) as I guess it's designed to move the key pins which aren't there. Is my only choice to try and pick the 4 driver pins? I have little success with the lock in working order I doubt I will be able to pick it now. I guess a good test if I can do it in a couple of months

Sorry ive just skipped through the thread so if im way wrong ignore me,

I think you say you have top pins and springs in a lock with no bottom (key) pins?

If thats so all you need to do is to lift the pins as high as they will go to rotate the plug,

An easier way would be to shim it as then you dont need to worry about binding orders etc,

I was actually re-reading the guide and the thought came across my mind but I wasn't sure what I could use to make the shims but I will give it a go.

I guess I wouldn't be able to use a half diamond pick for example? As that would be too short to reach the driver pins. Would I need to worry about the spool spins as I can see one as the last driver pin when I flip the lock 180 (so it looks the locks in America).

If your picks dont reach the back of the keyway you need to make some better tools,

Use the shims found when cutting up the security tagds found on items bought from the shops,

if the first two pins are pinned to the original key you could try inserting the key and then silghtly turning the key whilst smacking the lock bile side down on a hard surface

I belive he means that the diomond on his tool is too low to push up the driver pins into the bible, i.e. he needs a steeper hook rather than a longer tool. The lack of key pins will make picking it far easier, you need to pick the lock as normal but with the push the drivers where there are no key pins as far as you like into the bible as they cannot be overset (this could overcompress the springs however though this damage is minimal). Inserting a shim from the back as Shrub surgested would mean that when the pins are set they do not unset as a peice of metal splits them at the sheerline.
