I have rebuilt and repaired tens of thousands of these, and I have only seen two that have this part. Both of them were special function locks. They have a "passage" function knob on the inside plate. ..

This only works on models made before 2010. since then they have ised stainless steel for this plate that is non ferris and non magnitic so tis will NOT work on newer models. Also KABA has sent out thousands of upgrade kits to fix older units with the stainless steel plate.
+Wayne Winton So then all you would need is a small battery operated electromagnet that is pulsed on and off to cause the flag to have an induced eddy current as well and the trick would still work even if the new metal is non magnetic since it would still conduct electricity.
+Papa Gleb I have seen it. as well as Tobias video showing the same basic concept. his video and lawsuit caused kaba to make the stainless steel replacement part.

That flexible tab that moved when you placed the magnet there is installed only when you have a bypass function on the lock. A thumb turn on the inside plate fits into the oblong hole and when turned it allows the outside to be in passage mode. It is generally not installed. I always check for the factory default combo as many times the customer doesn't set it. Or try 135, 531 or any three button combo as people get lazy using this lock.

We did a security assessment at a major Washington DC university, I used the magneto to test 8 doors with the KABA lock, it worked on three but the magnet is so powerful it will grab the door, if it's metal, and will proved very hard to get off the door (it tends to grab the metal door, especially if the lock has the brass finish. It oworks so keep the fingers clear!
The Sparrows magnet has a pulling power of 95 pounds and on their web site a cut-away shows that the "sticky" part of the magnet is on the side. Harbor Freight sells magnet item number #36904 for $9. It has 150 pounds of "sticky", and is about 8 inches long and 1 inch thick and two inches high. Probably would do just as well on these locks. ALSO I use it when I drop a small nail or screw on the floor that I cant see to pick up, this magnet finds it., Also picks up roofing nails from the gravel driveway. Bob L
I have a 3" round by 1.5" thick N52 magnet. I put it in a leather sheath I made because all the socks I used to wrap it in just got eaten up. The leather has last several years of fairly regular use. The extended sides and handles I incorporated into the sheath makes it a lot easier to move it around and remove it from steel.
Technically, if you don't have the magnet, couldn't you just drill a small hole on the side and pull that lever thing without grinding the whole thing?
Wrap the magnet in electrical tape or heat shrink, save the magnet , save the door finish, and make it easier to clean metal from it. Lastly, makes it easier to remove
Is it possible or wrong ideal for a company to put a simplex door combination lock on the outside of the building if someone was to figure out the code and get inside? Has it ever happened before? Just curious one of the guys here at my job saw some reconstruction going on and they noted they be putting a simplex door combination lock on the outside for certain employees to get in
Product of Canada (2010). I think that this design is older than I am, and at the time they justified allowing this vunerability on the assertion that powerful magnets would remain too expensive for criminals to have.
Does only work on the unicans that have that bypass lever on the combination sleeve? I worked on a ton of these, and have only seen that one time. I believe it comes with the ones that have the option to leave the door unlocked.
Removing the steel "Flag" as he calls it, and the magnet will no longer unlock the lock. That part is to make it work like a passage lock, and it is not needed. It can be very easily lifted out and removed and will not affect the lock and the push buttons will operate normally.
Thanks for the tip! I was thinking of asking The manufacturer’s to replace the parts with a non magnetic stainless but your idea will be easier because I don’t have the passage option on mine.
Hi Bill, I never heard the term “insecure side” used in security. We use Exterior vs Interior; and locked side vs inside are the two I have seen over over 30 years. The word insecure has a totally different meaning, as in worrisome.
Watch out for metal doors! That thing will stick like you will not believe, sock or glove may not help. Many current locks are protected and this magnet is sort a little late into the field.
Does anyone know if this applies to the 6200? They're still being sold for north of $250 and the listings I find claim it's "vandal resistant" but I don't know if that's addressing this specific flaw.
So they need to swap out that flag with stainless steel and the magnet trick will no longer work. In any case, I'd love to see how it manages the combinations you describe. I assume it's completely mechanical.
Just found your channel and been watching your videos , Never knew anything about picking locks before but now I kind of want to try it ! How hard / expensive is it to get into as just a weekend hobby kind of thing ?
Cool trick. Don't really want to be dubbed as a grammar nazi but I do believe the reverse side of this lock would be the unsecured side not the insecure side. Unless of course it was anxious or unsure of itself.
that will only work on the models that have a passage function. (knob on the inside that can be turned to keep door unlocked from outside)... in 14+ years I've only seen 2 or 3 out of 200 or so.

I have been in the alarm business for 40 years. Like all products there is always room for improvement and this has been done. You have amateurs and professionals in the business. It all depends on who you choose and how much you want to spend. Consumers would spend $99.00 to protect their $100,000.00 + cars. Then they wonder why it was stolen. I have installed residential and commercial high security systems and they are extremely expensive. You get what you pay for. Just remember, in the state of Illinois and most other states you must be licensed by that state to sell, service and install security systems. In Illinois it's the IDFPR that monitors alarm company's. You will be arrested and charged with a class x felony if you get caught. Do your homework!

thanks you just taught someone how to break in my house lol

Does only work on the unicans that have that bypass lever on the combination sleeve? I worked on a ton of these, and have only seen that one time. I believe it comes with the ones that have the option to leave the door unlocked.
I have work on 1000 series as old as the early seventies and have never seen that piece of metal. In any case kaba corrected that flaw a while back.
Thank you sir
This also only works on simplex locks with the passage kit. Most (in my experience) do not have this.
Exactly. I was going to post that myself.

Nice demo thanks
Hi Bill, I never heard the term “insecure side” used in security. We use Exterior vs Interior; and locked side vs inside are the two I have seen over over 30 years. The word insecure has a totally different meaning, as in worrisome.
1:29 - “...this is the insecure side...” - I’m quite sure all of your locks have an insecure side! ;)
I wonder if you can protect it by puttng a reverse field magnet on the flag that will repel instead of being attracted?
Watch out for metal doors! That thing will stick like you will not believe, sock or glove may not help. Many current locks are protected and this magnet is sort a little late into the field.
It's interesting because this lock didn't have the passage function on the back plate but it did have that lever on the chamber
They come from the factory that way. Just remove or tie down that part.
Would this magnet work on Alarm Lock Trilogy T2?
That's ingenious!
Does anyone know if this applies to the 6200? They're still being sold for north of $250 and the listings I find claim it's "vandal resistant" but I don't know if that's addressing this specific flaw.
could you try and see if a neodymium hard drive magnet will do the same thing?
Are most of these locks nowadays made of aluminum?
So they need to swap out that flag with stainless steel and the magnet trick will no longer work.
In any case, I'd love to see how it manages the combinations you describe. I assume it's completely mechanical.

I wonder if they made the piece out of brass now?
ihave one made in 2003 with a lever handle , and it wont work on that one. only the ones you demonstrted
Cool !!
Bill, does that work with any other types of locks??
Any other tricks you can share with us ??
Kaba changed the design to eliminate this vulnerability years ago.
Yes, but if security managers were too lazy to make the retrofit to prevent it, then it still works.
What I would like to know is what's the minimum pulling strength the magnet must have in order for this to work?
324 Yektapuzules, no less. Heck, how am I supposed to know or measure THAT? Try asking Sparrows how much their Magneto exerts.
Well, bugger. I have these on "secure" areas in work because their electronic locks were so shoddy. Every day's a school day.
that will only work on the models that have a passage function. (knob on the inside that can be turned to keep door unlocked from outside)... in 14+ years I've only seen 2 or 3 out of 200 or so.
weird thing is that yours doesn't have the passage 'lug' on the the back page... goes in where that hole is.
Is the simplex 9600 line this easy to defeat?

Casing is NOT IRON/STEEL, otherwise the magnetic field would not penetrate. It must be some non-ferro probably Al-based allow.

You failed to mention that this lock is equipped with a passage function. Anybody who is a professional knows what I’m talking about.
Explain please :) My google fu is not turning up what the passage function actually is
The simple fix is to jam something between the lock and the side. Done, that flag will never move
