Unusual Yale lock?

[ossie]

Hi all,been picking for a while but still very much a beginner,i can open all the dozen of the locks i own but this one turned up today and it seems a bit different.
The keyway is straight and the pins,four of them,are different to normal being sort off cup shaped,i think i have the pins set but won`t open,would this lock be a double sided key perhaps?

The lock you have uses flat wafers instead of round pins. This is the same style lock plug that you would find on most cheap file cabinets, lock boxes or furniture.

Do a search for cam locks or wafer locks.

It is a single sided wafer lock. The dimple to guide the key clearly shows that.
When you say it wont open, do you mean the shackle or that the cylinder wont turn?
In the second and third pictures, it looks picked...
Either way, it looks pretty corroded, it can be hard to get those moving again.
I have had success with an overnight soak in CLR. Some can take two days to loosen up...
I have soaked some even longer but them old padlocks themselves seems to dissolve and gets all pitted....And still wont open...

Good luck!

Many thanks for both replies,you have me thinking now that perhaps it is as you say, allready picked,it is in bad condition but the cylinder does turn perhaps an eighth of a turn before any pressure goes on the "pins" or should i say cams.
The position of the cylinder is not in the usual padlock place so to speak,looks a quarter of a turn out,so a good couple of days soaking and then i`ll have another look at it again, especially as it`s a cheapo lock and shouldn`t really be a problem to pick.
Many thanks for your help from across the pond,cheers.

After a few days soaking in light oil ,then a splash of two stroke,seems like the lock was just all gunked up and now can be opened easily,very easily,not much of a challenge but i have learnt and now also have a different type of lock in my collection.
Many thanks for your help and ideas.
