I usually don’t post follow-ups to ongoing discussions, but this one really took my attention. Having fun solving that lock, from the post below (Lock and Key puzzle)? I didn’t have any, but found out it is originally called Danlock, and was designed by Israeli craftsman, Dan Feldman. Also, I have more pictures and info, I didn’t provide last time. Apparently Danlock comes only with two keys – one attached to the shackle, and the other is broken (no trick there). I also found out, that it’s rather more difficult to get the lock back to the same state as it is delivered to you. It involves the solving of at least 3 quite distinct puzzles.

I searched the whole web to find the solution, and couldn’t find one. Maybe it’s better like this, since it’s much more fun. I believe it would be much easier if I actually had this item in my hands. For now, my best guess is that the lock is infact tricky, and that it can be opened with left part of the broken key itself, then maybe with other part (keyhole not as deep as the broken part), or maybe without key. Cool game! Does that little ring attached to broken key has any role in this? Are the numbers on the key some kind of combination? I emailed Dan Fieldman (the creator), and hopefully he will participate in our discussion. Also, solutions like: “Use the chainsaw“, “Photoshopped” etc… are invaluable.

    Couldn’t it be possible that the key isn’t broken its just a bottom of a broken key and the top half is the actual key?

    • :-D says:

      heres yur anwer
      take the broken key,superglue it back together then get a new on cut and hey presto! you can now get yur wife out of the garage!

    • Dave says:

      note that the 2 keys are different…just sayin’

  2. greg says:

    Ok this is my complete guess. you stick the broken part of the key in then use the head with the ring to turn the lock. then use the other key to puch the broken part through the lock and out the top.

  3. awesome girl says:

    grrr
    you gave me a headache
    just press the next random illusion and get over it!!!!

  4. kristina says:

    it never actually shows where the lock is completely closed. it could be touching or almost touching but not actually locked yet.

  5. butch says:

    ^^^ that’s the nearest answer! next!

  6. Somnath karmakar says:

    its not possible to fit the key into the arms of the lock, i mean the hole is very narrow to fit into that.

  7. Somnath karmakar says:

    WTF man…The answer is, break the damn available key from the top in such a way that it can be inserted in the key hole, and open the lock

  8. beautysleep says:

    who says the lock is locked

    • panaeleas says:

      because its a lock and looking at picture and not holding this in your hands trying to figure this out seems like a fools errand

  9. kuki says:

    u dont need a key to open the lock…. press the top of the lock down or something n wallahhhhhhhh … it should open

  10. martin says:

    Padlocks normaly come with three keys – use the one that’s not in the photograph! Easy!

  11. danny says:

    i think that the broken ‘business end’ of the key goes in BACKWARDS and then you put the other hand held end in normally and ‘HEY PRESTO’. just a guess though.

  12. Neo says:

    (TO OPEN) …..You take the end piece of the broken key put it in the lock, then use the other half to insert behind the piece and turn. the lock will open.

    (TO LOCK)….. Remove the back half of the key. Hold the lock in your palm with the bar towards your palm, push in on the bar using your fingers and thumb on the locks body until the bar is in the locks hole, but not clicked. In one motion rap the bottom of the lock at an slight angle on a hard surface while locking the lock at the same time. This will allow the piece of key to to be released when the tumblers align upon locking the lock. Use your fingernail to pull the piece out.
    The whole key is never needed.

    aaa, boltcutters dude

  14. Athanatos says:

    You forgot that this is in section “optical illusions” :)

    As Somnath karmakar said – the hole of the key is not enough to fit the arms of the lock.
    In fact, the whole key is free, the arms is cutted and the key is “inserted” in the gap.
    What you see is just an illusion :)
    Happy New Year!

  15. kerry says:

    this is a really cool trick but its just an illusion. you cant fit a key onto a padlock

  16. oversize bag says:

    this is just what they say it is.. an illusion nothing more, nothing less

  17. cliveawalsh says:

    Ive got the lock and heres how to do it.

    You put the 2 parts of the broken key in the lock like a normal key and turn the lock to open it then turn back and remove the top part of the broken key. The shackle comes completley out and conceals a long point you use puch the second part of broken key out.

    Thats only part 1. Theres more required.

  18. blah says:

    ok, so how to solve this, u get a piece of thread, theres a hole in the bottom part of the key, and you put it through, n then u use the bottom part to put inside and use the top to push and unlock, now as soon as u unlock it, u can pull it out the bottom part with a thread and bring top lockin part around and close it and its in the original condition

  19. Dead Arist says:

    This is simple. Look at the lock with key. The lock is cut where the key is held (the hole of key is bigger than the hole of half key. Just slip off the key and insert it into lock!!

  20. Kat says:

    Who says the lock is actually locked? It dosen’t show the lock from the right angle to see if ti is locked ;P

  21. ma haji says:

    You put the 2 parts of the broken key in the lock like a normal key and turn the lock to open it.

  22. Tristan says:

    i believe that the key is double ended, there us the fake “broken” side in which you will try to use to open the lock. but if you look on the opposite end, there is a little edge sticking out about 1-2mm, i believe that is all that needs to be inserted into the lock to open it, anything more will activate the tumblers and prevent the key from turning

  23. MIKE says:

    key has one side cut out so it appears to be around the lock ,but it actually is not

  24. ASHUTOSH says:

    Because there are locks with 3 keys.
    There might be third key not shown in the picture.

  25. ASHUTOSH says:

    Or, the lock might be not locked at all as we are not shown the front part of the lock.
    It might be optical illusion.

  26. viren says:

    i think the broken key is different from the one in the lock.

  27. chris says:

    the “broken” key appears to be a BUMP KEY

  28. Naina says:

    seems that the two broken parts does not belong to the same key…

  29. jonyah says:

    Just use the coke can trick to open it.

  30. Harry says:

    1. The 2 keys are cut differently, and one is broken, so the complete key will open the lock.
    2. The lock is not snapped shut because they only show the “other” side.

  31. James says:

    All wrong, it’s easy to get apart geting back together is the hard part. It’s one of the best puzzle locks.

  32. o.i.e. says:

    grab the front part and unlock it duh…

  33. cupcake says:

    impossible only way is that the lock isnt locked

  34. Jake Darwin says:

    This is one of my favorite puzzles.
    It’s actually not too hard to open. stuff the key shards in (I know you’ll be afraid you won’t be able to take the piece out but it is possible once the lock is opened) and turn it (kind of tricky but possible). The challenge then once it is open is returning it to the original state. I gave you the first part but try to figure out how to lock it again if when you used the good key, the key is off the hook when it is locked (the lock must be closed and needs a key to lock it). And if you lock it with the broken one, the pieces get stuck inside and only come out if its unlocked.

  35. Cassandra says:

    Eh, I would just go and buy a new lock….

  36. Dan McGuire says:

    I say you take the ring off of the broken key and pick the lock…

  37. Sakigehi says:

    Based on the links on the previous post (Lock and Key), I saw some illusions that I know the solution.

    The lock isn’t actually locked. It was taken at an angle where the lock appears to be locked.

    OMG! SLOW MINDS!

  38. Linzi says:

    Y not just buy another one and unlock the first one with the key thats lock to the second? :/ im just saying! xD

  39. Alex says:

    It’s actually pretty simple.you can open the padlock with the broken key. you can just introduce the top part of the broken key into the padlock and then with the bottom part you can push in and twist. you can also lock the padlock back and leave the top part of the broken key inside and only use the bottom one to twist and open. the key locked into the padlock is just there to play a little with your brain and think that you could only open the padlock with the unbroken key.

  40. nikita says:

    show pmne open lock, I do not believe you solved it

  41. James says:

    Use the wire that comes on the “head and shoulder of the key” to set the pins inside the lock and use the shoulder of the key to turn the cylinder.

  42. Craig says:

    I actually have this puzzle. There is certainly some interesting discussion going on about this. I will say this, the two keys are different (despite the one being broken). Both keys are required to solve the puzzle. The key ring itself is not needed.

    Cheers!

  43. Jim says:

    Stick the broken end into the lock. jam it the rest of the way in with the larger half. since the smaller half will be pushing up the necessary pins up inside the lock, and the second half will have a small part inside, you will be able to turn it and presto. Does that make sense or am i missing something?

  44. gavin says:

    you put the top of the broken key in the lock then push it in with the bottom of the broken key and it opens

  45. Anonymous says:

    It’s too easy >_>

    Get a bobby pin, pick the lock, and you’ve completed a pointless puzzle XD

  46. panaeleas says:

    I broke a key off in a lock once it broke a little ways up from top and I left the other piece in the lock so i could insert it in the lock with the broken piece and get it to turn
