Card lock breakdown.

[caitsith2]

I have a card pad lock, that uses a card with holes punched into it, as the key. (I had 2 of them, but lost the key to one of the padlocks, so I took apart the one I lost the key cards to.)


Here is the card padlock and matching key card for it.
.

Here is a close up view of the keycard, along with explanantion of the code.


And Info on disassembling the card padlock, if you ever wish to do so.


Now for some insides of the lock.

(The top piece has notches in it that prevent the lock from opening if the holes in the card are too big for the pin. (The top half is shown on the right.))


Here are the pin/spring assembly removed from the lock. (I intentionally rekeyed this lock, to work with the existing keycard, unfortunately, I had to remove one of the pins/springs, to do this, as the original key card did not have the same digits as the key card this lock was rekeyed for. (And I ended up losing that pin. There should be 4 of them in a normal case of disassembly.))


Another of the pins, closer up.


Lock disassembled one step further. Here, If the holes are too small for the pins, then the bottom piece prevents the lock from opening with that card.


Overall. Picking this type of padlock should be possible. It would just be a matter of applying tension to the lock pin sliding assembly, and using a pick to set the 4 pins to the correct heights. (I haven't managed to pick this yet.) This lock is most likely able to be opened using padlock shims.;


(I did at one point use this lock for my high school locker. The only problem was that I would once in a while forget the key card for this lock, and even came really close to having it cut off altogether because of that.)

nice post, thanks!
The pics could maybe be a bit more in focus, but I think I can still guess how this lock works.

And of course: Welcome, have fun around here

Cheers,

As I only had one card, and wanted to have a backup of the card, I have done some experiments to duplicating it. (The locks come with 2 cards, one credit card size, and one that is smaller.)

As it turns out, If you have these drill bit sizes, it can be done. (Duplicated the card onto a reloadable walmart shopping card. (Not on the magnetic strip e of course.))

7/64 for the small hole (size 2), and 11/64 for the large hole (Size 1). Size 3 does not need to be drilled into the card blank at all.

Well that's a pretty darned good newbie post.

Who makes this lock? i want one!!! Nice post!!!

[caitsith2]

I have no idea who makes this particular padlock. I have however found luggage padlocks based on this type of keycard, which is made by "Samsonite". These are best found on ebay, and the sellers of these appear to be in the United Kingdom area.

I have not found any other card locks of the sort.

Here are pictures of the key card copy I have made, using my (completely empty) walmart reloadable gift card.

Duplicating the key card is not an issue for me.

Is there anyway you could take some more picture sthat are clearer???? I'm having a hard time seeing how this works and these 49 yo eyes of mine aren't making it very easy... What is the section above the 3 pins? Where does the hasp get locked? What happens when the card is inserted?

[greyman]

Well done - I don't think anyone's posted one of these before. I think the Japs are pretty keen or were keen on these card locks. I have seen a Saiko brand lock with a card with more holes and I think they have cards with up to 20 holes - but binary, ie only 2 pin sizes.

The unit I have is identical to the one posted except for the branding. Mine has Boss as the manufacture and it shows a US pattent on the bottom.All the markings are identical otherwise

Here are some clearer pics of a lock i have.



This is the lock in the locked position (note the left hand cable connection is fixed, the right (empty) is the one that the cable locks in and out off)


This is the lock in the unlocked position. The whole block with the pins in moves and is directly connected to the locking shackle above it. The lip on the right hand side of the block is what the card pushes to move the block and unlock the lock.


The next pic shows one pin false set so its avoiding the block moving (in case you put a blank card in, the pins would depress stopping the lock opening)


Next is a close pic of the pin block and locking shackle. You can also see the groves in the case where the pins catch if the incorrect card is inserted.



Hope it clears it up a bit. Simple lock, easy to pick / bypass.

Cheers
Jamie.

On one of your key cards, there should be a code for it. Im going to guess the code is 1231. (assuming that 1 is the large hole, and 3 is no hole. (and assuming that The first digit is the top left, second is top right, third is bottom left, and fourth is bottom right hole.)) (If not 1231, then 3213)

Your lock casing seems to be completely identical to mine, just the locking hasp and label is different.
