unusual tubular lock

[Rickthepick]

Borrowed a tubular lock that has 6 round headed pins, one normal looking pin and two ball bearings in the keyway.
No locating notches as such.
My brother in law works with games machines so im assuming thats what its for.

Gonna have a play now and see if its pickable

Any ideas what its called?

I dismantled this interesting little lock and this is what i found:

6 main pins of varying length followed by 6 spooled pins.
the 7th pin is just a short pin already on the sheer line
13 small pins for each bore holding springs back from the sheer line
ball bearings seem to be a preventative measure to stop tubular lock tools and need to be fully in the keyway to rotate the plug

Mission to put back together but it seems to function much more smoothly now. Maybe i will now stand a chance of picking it

....12 pins... ahem... too many beers when i counted

Rick

these are located on deposit boxes often found in gas stations and should be viewed as "locks in use"

They dont have the external "Drive" element of a standard tubular lock to counter standard defeats

[Rickthepick]

i havent the faintest idea what any of that sentence means please explain

CompX National Keset cam lock.

cheers for that. Come to think of it i have seen one on an ATM machine cover.

Any idea what flat headed pin 7 is for? Im assuming a locating point for the key

Index marks are only needed to reference key position...
