Picking locks with spool pins (Rectification: serrated pins)

[Falken]

Hi there,

I'm pretty new in lockpicking (1 month) but I practice a lot. I could open a lot of basic european door locks (5 pins) in a few seconds but I still can't open locks with spool pins (I believe) like this Bricard lock.

I can feel the first pin has 3 levels of "position", so it seems to be a sort of spool pin, but I think there is at least one other pin like this, I can't determine it... I succeeded 2 or 3 times, but it never happened again. What is the best picking solution in this case? Raking, picking pin one by one... ?

thanks for your help!

Edit: according to Bricard, this lock is "Equipped with multi-form driver pins hindering lock picking." so maybe not spool pins.

I suppose this lock to be equiped with security pins as it's pretty hard to pick and gives bad feedbacks, but I'm not sure that the concerned pins are spools. However, for french people interested in spools pins bypassing, just have a look on this link http://membres.lycos.fr/placeboseb/lab/ ... -part1.htm

After practicing 1 hour I'm finally able to pick this lock, here is a picture, you can see the pins, there are no spool pins, but the design of the active pins is not usual, what kind of pins it is?

They're serrated pins... with one serration.

Ok so we now know that Bricard's locks security pins are serrated pins

I enjoy the straight diagonal pinning
