What they heck is this padlock tech?

[JoshuaWest]

I was recently hunting down new locks to add to the collection, shopping an an "Asia direct" type shop (knock off junk etc.) and came across a padlock with a key unlike anything I've come across.



I imagine discussion around the lock is either restricted to the advanced forums (If this technology is actually "high security" as noted), or it's simply a modified warded lock (judging by the key?)
Rest assured, I'm only looking for the name of this type of locking mechanism and key!

Not sure where to search without a name!

Thanks All.

Neither. Look under "ABA" lock. Essentially it is a stack of spring loaded discs (washers on springs). When the key aligns the washers with grooves in the lock body, the key can be turned.

They are a bit tricky, but not horribly difficult. Make some picks that look a bit like tweezers with a slight notch in them on the outer edges to hold the discs level as you press them down.

Good luck!

Thanks Gordan, You're a champ.

Found this after a quick search: (For future noobs)

I note that the ABA lock is a flat version of the same thing, but what do the "protrusions" on these barrel type keys do?

Same idea for function.

The protrusions are what turns the plug.

GW,

How do you feel this mechanism compares to an old Wise padlock concentric tube mechanism? Would you call it a distant relative?

Thanks,

The Wise padlock is much simpler. A single pin, surrounded by a larger pin, surrounded by yet another pin. Cut it in half through the round part. Now you have both the key pins and driver pins. Add springs, and you have a wise.

The ABA lock looks like the inside of a Diamont body. Put the wafers in line with the grooves, the plug can be turned. If I had an Ottoscope and a couple hooks, could open the ABA. The Wise requires a small poker of some type. You can even see the shear line on the wise lock.

Yes, I think these are closely related

I think it's a pretty cool lock, JoshuaWest thank you for the link that is a great demo of the principle
It's rare to see so different and unique locking principle.

Of course! Silly of me to have missed that.


I'm happy to help when I can!

I definitely wanted to know more about this one, glad I asked!
