I worked with Kaba Japan (Nihon Kaba KK) before, I didn't know they have this reduced kaba star just as JN (which is just four rows, while a typical Kaba star, for the EURO market, is five rows)... it is reduced to the capacity of those with three rows(like kaba Ace)
Sounds like the heavy use has worn the drivers into more of a tapered shape. Causing less crisp feedback and you having to pick them more than once. Or am I off base there?
So if the driver keys spring out then you won't be able to completely rotate and open the lock? Do you then have to take it apart to fix it? Driver pins*
In many high-pin-count locks the drivers are sized such that they can partially fall into the keyway and block plug rotation, but you can use a flat tool to lift them back out and keep going. However, in certain locks the drivers and springs are narrower than the opening of the keyway, so they will spring out of the lock entirely if you don't block the keyway with something to hold them in place. The lock can be reassembled afterwards by taking it apart and reloading the drivers, but you need to make sure that all of the springs are out before you continue rotating the plug, otherwise there's a pretty good chance of mangling the springs.
@@legendofthesamurai Thanks for the reply. Unfortunate that these are not as secure as one would think. The driver pins fall through the slit in the plug when it's rotated right? Why is there that slit? Is it just for saving space? Edit: Nvm I was under the impression that this is special for dimple locks for some reason, but I see pretty much all plugs are like that. I'm assuming easier to manufacture. Not sure why I thought normally the keyway would be completely encased by the plug on all sides.
@@bakirev Just because a lock can be picked does not necessarily make it insecure. The keyway is open to the edge of the plug because it is far simpler to cut a rectangular slot from the edge of a piece than it is to sink a rectangular hole in the middle of one, and under normal circumstances (operation with a key) it will never be an issue. If anything it serves as an extra layer of tamper-proofing, as missing drivers and mangled springs are evidence that the plug has been turned without a key.
@@legendofthesamurai I saw an ad from kaba on youtube were they ask an "expert" lockpicker if he was able to open it and he wasn't able to after trying for 15 hours. Left quite a sour taste in my mouth seeing you open it in a jiffy.
With the key under your eyes, serving as a blueprint, this was way too easy. Some locksmiths can memorize and recreate keys just by looking at them once.

Nice Video! Switzerland also uses Kaba Star for almost all residential buildings
Kaba is from switzerland.... it's a swiss company..
Very nice.... Will you please show how to put these components back so that this lock is ready for use again..
Good Job -- Nice to see another similar to Kaba 20, Miwa JM, with 4 row Kaba Star-- and such a pretty colored key -- excellent
That was a bench pick, what about picking the lock installed in the door so you have to work in a awkward position? Still as easy as shown here? 🤔

My thoughts exactly, though the taper is smaller than I have the capability to measure.
Way out of my league, but very interesting to watch. Thank you.
Smooth. Enjoyed it. Good job !

@@legendofthesamurai I checked again they actually gave them kaba experT cylinders and not star. Are those a lot harder to pick open?
