- Professor Justin Cappos from the New York University Tandon School of Engineering demonstrates how to open a Master Lock without knowing the combination in five to seven attempts. Also, learn the vulnerabilities that allow you to open many other types of locks, including a bike lock and a luggage lock. Video shot and edited by Ted Shaffrey.

I honestly ran around my house screaming when my lock opened up! Thank you this was so awesome to try and figure out <3
Finally! A tutorial on how to do this that isn't just 'I already know the combination, so all I need to do is adjust pressure to make it look right on camera' kind of video. You go into the why and explain well. For reference though, I am a math major so I can see others struggling with the modulo arithmetic, but w/ this I was able to find my old combination so, cheers mate!
Nice, thorough explanation. I still can't open mine but your video gives me hope.
Thanx i saved all my locks i firgit the combos for . Now ill have my locks back
Great explanation. I was shocked when I finally got it open, as I didn't expect it to work. 😄
I had a bike lock just like that when I was a kid. I thought I was clever when I removed the keeper spring and jumbled the rings to change the combination. My dad gave it a good pull and popped the keeper spring out and the lock opened. So the combination was "give good pull".
Thank you. I'm waiting on the combo from Master lock, but this worked to solve the lock combo without having to wait. The combo works, so I will get to double check my work once Master lock gets around to replying to my email. Thanks Ted Shaffrey.
I’ve been trying to unlock my old gym lock for 2 hours now
I just unlocked my lock . Thank you so much for the video.
I jumpscared myself when mine opened. 😂 I've been trying for three days. I really needed to see what was going on inside - not an animation. Thanks for prying that thing open. I want another lock to crack now lol.
Thank you, worked perfectly - of course on the last possible option!
Excelente explicación, muchos saludos desde saltillo coahuila MÉXICO.
while listening to this scholarly dissertation on modulo 4 math applied to master lock combinations -
This video finally made me remember my code combination.
I wanted to thank you for your video. My lock was really rough and I couldn't decipher Number 1 but could make out number 3 clearly. So I used your rules to create a spreadsheet of possible Number 1 and 2s based on the rules you presented which resulted in 56 possible combinations. It was the 44th one in my list that opened it. I'm stubborn enough to see if I could only open one only feeling the 3rd number and I guess you can. Thanks
I have master lock...and been trying for 7days already....tq...nxt video plss...
i could only find the first one but did a quick bit of calculating and a good soul read of my lock and figured it out!
I was waiting for your Leatherman to break prying like that. Glad it didn't.
THANK YOU for explaining in detail why things work the way they do. Every other video did not help me and seemed to be happenstance that they could unlock it. This made a lot more sense to me and with it I was able to get my childhood lock back open.
