16! (which is 16*15*14*......*2*1).

Thats if you use all so you have to add if you only use 15 then 14 ... so

16! + 15! +14! +......+2! +1!
then you have to subtract the repeats and theres only 16 combo's that use the left out button last [hence repeats] so the total repeats would be 16 + 15 +14 +13...+1 as which is 136 (a small number)

long story short mathematically there should be just above 22,300,000,000,000 combos, (ways to arange 16 things + 15 things etc...[minus repeats])

which is good news cause they claim there is only 40,000 wich means at any given time there are actually 558109813 DIFFERENT combinations that will open the lock.

lol that was fun.. i would recommend every get and learn to use Matlab.. its can be interesting.

So ForFun just start hacking away at it, although there are 22,300,000,000,000 combo possibilities 558109813 of them should work due to machanical limitation so that leaves you a 0.002% chance of guess it right.

ps. still look'n for more info for ya though its look'n scarce.


Yep, Matlab is great. Unfortunately it's not affordable to most people at around $1000 a pop. Not sure if I agree with your above calculations, on the other hand.
If something has 2 possible positions and there are 8 of them, I calculate 2^8=2*2*2*2*2*2*2*2=256 different settings. There must be more to this padlock than meets the eye if the manufacturer calims 40,000 combinations. Wish I had one!

pushbutton padlock

I had a quick look at my Padlock collector book. A few other manufacturers were putting out locks like these. The earliest one seems to be Clark's patent combination lock from 29 Feb 1876. There are some other "indicator padlocks", but I'm not sure if the mechanism is the same. Can anyone locate the patent for the American Keyless combination lock? Maybe it was just a rip-off or resurrection of someone else's design.

SemiShady, rereading your post there. If there are really 16 buttons on this thing, and you can push them in or not, then there would be 2^16=65,536 combinations total. There may be some excluded ones depending on the mechanism. The 40,000 figure sounds pretty reasonable to me.
