Bi Locks

[vector40]

A computer pick is similar to the concept of an automative "jiggle key," as I undertand it; it's a pseudo-rake in a complex shape, designed to imitate the standard pin heights for certain brands/models of locks. They come in sets and are generated by computer algorithms for the relevant types of locks.

I think I read that bilocks could be bypassed using packaging foam. However that might have been a different lock. To actually pick it however just pick it like a normal lock by applying tension, and find the binding pins.

--In Australia i have noticed some locks called Bi Locks. Its a pin tumbler lock with the slot for the key in the shape of a U so that both tips of the U have pins(6) on each side. I have got my hands on a Bi lock key and i have read the words Australia Patent on it so i was wondering: has anyone out there seen bi locks in other parts of the world? If so, is at all possible to pick these locks because to me it looks a little difficult to do so. I have seen these locks on nearly all the doors through my university.

You are talking about NTU Casuarina.....I rekeyed all 15000 of those doors in all 5 campuses back in 1996....we changed it all to QCC at that time....but before new gen...the system was written by Barnes in Qld...but Darwin L&K had the local contract....I was the tech

Doesnt operate that way....the pins dont hold position with tension...the fingers of the side bar dont allow this to happen...

In theory...you need to pick the right side bar first...but after lifting the side bar blocking pin first....then pick the left side bar

On the foam key thing, I think it's unrelated to BiLocks, which are sidebar locks. The foam key impressioning technique is applicable to pin tumbler and wafer locks that require only light force on the tumblers. You may be thinking of some dimple locks or the Bricard wafer lock.
