something i have yet to come across....

...until tonight.
i was at my friends house earlier tonight and i was picking various locks, anyway i tried out the lock in his conservatory, it was a migel or something like that? :S
its just a 5 pin tumbler, in pvc type doors.

i picked it in a couple of mins but after turning the barrel round 180degrees, it stopped, then after closer examination there were more 'pins' on the opposing side to where the 'teeth' in the key would be. this prevented getting a key in and picking. eventually i figured it out and applied pressure with a long torgue wrench and spun it the rest of the way and was sorted. but what were these pins?
anyone care to explain? lol
cheers

This is the reason we tell everyone not to pick locks in use. The pins call into the keyway when the plug is turned halfway. You were one of the few to figure out how to fix it yourself.

[jd90]

yeah i wont be using ones in use again lol.
so is there a name for this mechanism or what?

[freakparade3]

It's not a mechanism, it's just the pins that you set fall back into the keyway at 180 degrees. Push them back up and the plug will move again.

[jd90]

no thats not it, there were pins on the OTHER side :s
they came into place at 180, so at the top there were the regular pins...then at the bottom there were these other pins than came into play.
preventing a key to go in or the barrel from spinning

[bumber]

go get the lock you speak of and tear it apart and show us pictures, if anything else that will give you an understanding of how locks work and us some cool pics to look at

[jd90]

no can do unfortunatly, theres no way i can tear it out of his door and then tear it apart lol. sorry

[StabbyJoe]

not advised to tear apart a lock that's in use by someone else... but if you decide to, anyway I'm keen to know what's up with the second set of pins?

[jd90]

well i can try and get a pic of when th second set has popped out, but wont be until next week....

I have never heard of a lock with pins on top and bottom. I admit I have not seen every lock that exists however. I still say it's the key pins causing the problem. If you tell me the brand and model of the lock I'll gladly order one and check it out.

I think fp3 is right.
If you look at a euro cylinder lock - there's a key; below that are "key pins"; below that are "driver pins"; below that are springs.
When you turn the plug 180 degrees, only the "key pins" will turn inside the plug and be at the top,
the "driver pins" and the springs will still be down there. And pop up at 180 degrees.

Cheers,

ill get the brand, name etc. and some photos for about thursday, be sure to come on and have a look

get a tubular lock you have to repick it every eighthof a turn. Automobiles sometimes have locks that turn to different switch positions, also elevators, whereever you see mechanical locks on electric circuits.
