Cracking a combination lock 

Yeah. Mine jammed up and now I look like I'm trying to steal my own bicycle.

Thanks for this have just popped out and now I have two new bikes

This actually worked for me. Thank you! I accidentally reset my combination lock code, and it's a HUGE hassle for me to get a new lock (I currently live on an island!) so it was extremely valuable for me to figure out how to crack my own lock. Definitely not trying to steal anyone's bikes! Thanks for this.

Cheers, that lock was stuck on my bike for a couple of years. Easy peasy!!

Used the method in Sir Jethro's video to crack / open a very similar-looking, Titanker 4-number combination lock, which is maybe 3 years old. It took me several tries (taking breaks between attempts due to my old, achy hands), and I had nearly given up, but it helped to use more tension, and it also helped to work the cable to it's center on the bike tube of where it was stored in order to get a better grip on each end of the lock mechanism for applying extra tension. I did this in the quiet of my garage, which helped with hearing what was happening. Going in the same order, right to left, the first number had more of click and drop-in with some play in it - the next two numbers seemed to just stick - and the lock simply slid open on the fourth number, and I'm still relishing the small victory. Anyway - it was not obvious upon finding each number and had to persist, but the method worked. Thanks you for the video, Mr. Jessop.

Worked perfectly. Tried a number of the other related videos, but yours was the one that "cracked" the case. Thank you!

Knowing the correct code has a huge impact on perception. That is why a scientific way is to have a blinded test.

Thanks...I had the same POS sitting in my garage that I forgot the combo to.... cracked it in just a few mins.

Neat trick! The point of locks is to reduce the temptation to steal the bike, especially by casual passers by. The pros have the tools to overcome most locks.

I appreciate it. My kids forgot their combinations to their locks. I’ll have to try your method to unlock them. Then tell them I used “magic” to get their locks opened😉

Thanks a lot! I was able to unlock it. I bought the lock about 20 years ago and have not been using it, so the combination number was completely forgotten. Your video helped. Thanks, again.

Damn! Working on this lock for 5 days and this video made it easy. Unlocked in a minute

I was locked in by accident. This video saved me!! Thank you!

Just did so and it took about 10 seconds, I only had remembered that the first 3 numbers.....thanks for the video, had to remove my trashcans for major demolition

Hey Jethro, This is brilliant! It worked on my lock. Got it open before the end of this vid. No more cheap locks for me! LOL Cheers from USA! -Duane

found my old bike lock the i forgot the combo for. it's been YEARS. I am shocked on how easily this f-ing worked!!! Thank you

It works. I was able to unlock my cable lock just now. I forgot the combination i set and was able to open it now because of your helpful video. Thank you!

I had forgotten my combination number and unlocked this in seconds after watching your video ! Thanks !

Thank you very much! Somebody tried to break my lock of such type, but fortunately police was near and the thief ran away before he could unlock it. However, the thief broke the lock and somehow changed the combination of it, so that I could not unlock it. Thanks to your video I found out what is a new combination, unlocked my bike and threw this lock directly into the trash bin

THANK YOU I tried so many tutorials but this was the simplest and best explained

Thanks Jethro for this video!

Tried it with exactly this type of lock, and frustratingly failed to break in, so will be continuing to use the same lock!

Found a lock just like this on the beach. It was locked. Watched your video and in less than 2 minutes I had the lock open. Great tip.

Maybe I should've bought a cheaper lock, I've forgotten the combination of my ONGuard and no amount of pulling and listening for clicks is working.

I work at a place that had a bike lock on a railing. It has been there for years. I couldn't remember how to unlock them, but I watches a little of your video to refresh my memory and POOF! I have a bike lock..lol. The people working there weren't too happy about me taking it. But it belonged to no one. LOL. Mine Now SUCKERS! :) Thanks for the refresher course...lol

This worked. Thank you Jethro!

Thank you Mr Bond. Give Q my best!

There’s a lock just like this on the bike rack at Publix in Cape Canaveral. I was there today and saw it and said “...bet there’s a video on this!” I’m going to go try it tomorrow. I’ll let you know how I did. Thanks. Love your accent!

"Sherlock Holmes cracks his own bike lock"

found a bike lock, wanted to use it for my new bike... just popped open after 10 minutes trying this. sweeet

Oh my goodness thank you so much!

Amazing lost my combination and after watching your video it took me 30 seconds thanks

Thank you so much, I tried this and it worked perfectly. I just got a bike lock, and I have a shitty memory when it comes to certain things but I got in the right spot, it was 1 number off of what I wanted it to be. Thank you so much

Yup, it worked. I was sceptical but it worked on a 4 digit Masterlock. I'd started working back from 9999 and got as far as 6799 before I decided to see if there was a cleverer way. You saved me a lot of time.

I almost left you some real life hate mail thinking I was definitely not gonna be able to open it. But for the first time in almost 20 years, this damn bike lock is open!!

Big thanks dude! Got it open in no time!

Thanks for helping me get my new bike

I'm a safe engineer & locksmith by trade & a professional bassist but that's another story , This only works on cheap locks ,Go for anything that has a Sold Secure cert sign , Sold secure is owned by the Master Locksmith association & and it's by far the hardest test to pass .

I think it's a bit more difficult if you don't know the number. I think maybe it's psychological. Because I have one that I don't know the combination to and I'm having a hell of a time trying to open it. It's really cheap too.

Thanks, i forgot the combination and now can free up one of my bikes

Brilliant! Thanks!

Wow just bought a bike with a helmet and new bike lock but the seller forgot their combo. I watched this vid and BAM! Unlocked the lock!

Thanks a lot. It just opened up in a minute!

Just a tip, I bet a ton of comments said that keyed locks can be picked easily and it's true but people who actually pick locks are rare to come across in people who steal bikes and everyday items, and I'm in one of the worst areas in my state, but keyed locks are more easily bypassed and these methods can be heard and applied no practice involved, usually faster then on the lock you have, 3 to 25 sec is a average time for me, I practice but take a sec and see what your buying. Kryptinite bike locks 70$ range under 30 secs with a pick or paperclip and tension lol

Thanks bro I forgot my combination I used this and it unlocked in seconds 😁

Works like a charm!

I have a chain one with a similar lock, mine has 5 number combination. I tried it but I can't do it, it feels like it clicks into place but on wrong number. Went into a store for 5 min, came back and found my lock shaft partially open, probably forced it out. Put in my combination and it still works. Had a talk with some guys asking if they saw anyone forcing the lock and they recommend I don't lock my bike in city centre. It was a 150 pound bike.

I'm gonna try this out as I have a lock on my bike for a few years without knowing the code

Wow it worked. Thanks for video.

Literally 30 seconds to crack an old lock I've forgotten the code.

The video really helped me, thank you very much!

Literally took me 10 seconds 👍🏼😎... thanks Guv.

It is true - it works - my kids messed up the key combination and I came straight to RU-vid for a solution. I tried what you said and it worked 👌🏽

thanks! this worked for me 🤩 took a bit of finessing 👍

Between you and the "Lock picking lawyer" I'm thankful MOST people are honest. I only use mine on a bike I bought from Charity shop used for local shopping. it's not worth much, but even so scumbags have tried to steal it unsuccessfully!

Little Finger you're amazing bro. Got an used bike where the lock was old and kind of stiff. This method works best by far!! Took about 5 minutes. Cheers bro!

Thank you so much, that saved me a lot of time and effort !

Thanks a lot, that's really help

THANK YOU SO MUCH!!!

Yup. Took less than an hour. It's a rather strong looking lock but it opened. The 2 inside numbers where the difficult ones. The outside ones clicked into place on the first spin.

Damn... My kid forgot his combination, but I can't feel or hear any difference trying the numbers 🤦‍♀️

Forgot the code to mine and this doesn't work. The only difference with my lock mine has 0 where his has -

saw this, wanted to try it on my abus d-58292, when you pull even just you cant change the numbers, they lock up. i did try this trick on a cheaper version looking like yours, and the trick works there :) so seems like a trick for cheaper locks

Thanks a lot mate

I have a masterlock and i can open it by feeling, i want to improve it and use it. Do you have ideas to make the pick more difficult in my 4 digit combination lock?

Is there a way to open the lock if you put in the key before moving the switch back? My nephew was messing with it and I have no idea how to fix it now.

Excellent video I got it open in only a few minutes. Thanks.

Bro I forgot my code for it and I used this and opened it in 30 seconds

Opened in 40 seconds lol, thank you😭😭😂😂💯

Thank you, I had forgotten my combination, it worked for me :-)

Wait this actually worked!!!! Easily! Thank you soso much

I just opened an old one that nobody here at home knew the code. Thanks.

I used to work at Halfords where we sold these. A customer once bought one then proceeded to set the combination wrong. They brought it into me thinking they set it right and the lock was just broken, so at the counter, in front of them, in under 20 seconds, I did exactly this and demonstrated to them the combination they put it was wrong and how to set it right.... the customer then thanked me... And left with his new lock!! Really? If someone just opened my brand new lock in under 20 seconds right in front of me I'd have been a bit more "hold up, that was too easy, can I upgrade and purchase a better one instead?" haha!

Thanks, it worked !!

Very very useful. Thanks Jessop!

Great video, thanks for the info, i am not using these locks anymore.

You helped me.. thanks

I was messing with mine and I’m here now taking my own bike

Thanks!

I can't lie, I was thinking bulshit whatever I opened this video. I have that exact same lock and it worked the first time that I tried it. Within 30 seconds I was in it. Good job. Thank you, I can now use my ladder that I locked to my trailer. LOL

Thank you it matters to me 👍

Thanks bro i forgot my password and this trick open my lock

Yes it works it's different from others & it's really work

Thank u sir!!!

It really works man!!

It’s not really “worthless”, these items are physical deterrents, not “thief proof”. Most would be petty thrives on the street trying to jack a bike, want to be able to do it instantly and be gone, if they have to sit there for even a few minutes trying to de-code a lock; they are at greater risk for being caught / arrested. I wouldn’t toss your lock or anything, it’s still good for locking up while in a store or a college campus, something of that nature. If your bike is going to sit for a long while, number of days, then yeah you’re quite correct in being need of an upgrade to something a little more difficult to decode.

Thanks alot now i have a new bike

Nice one! Thankyouuu

I'm afraid that a lock picker like me would find a key type lock easy to open I suggest a disc detainer lock

thanks bro..i was going to buy but after this ...no to number lock..

Hey thanks alot! We were able to unlock a 5 year old cycle lock because of this trick!

WOW super it worked to me very thanks

thanks man i just bought a new bike lock and i forgot to ask what the combination was

Thank you

Be sure to spin the middle ones evenly, it’s easy to get false clicks if you’re putting sideways pressure on them.

Well you've got a new sub, thats for sure!

Not working my lock seems to click and tension on numerous numbers help

Lmao this worked in just under 5 minutes, thank you dude

I found a lock on the street or in dumpster, i forget and picked it up. I was able to decode it successfully once but then i messed it up or forgot the combination and now i can't decode it. It seems to have similar sort of mechanism from what i remember from when i actually had it open. The one i found is by a local store chain that imports higher quality Chinese generic products, so there can't be anything too particular about it. It is not a cable lock but a chain link one, plastic covered, and it has an LED in one of the surrounds, to make entering the code in the dark easier. I would love to decode it and actually end up using it :D I run an unattractive looking bicycle where slowing someone down by a few seconds already going to keep it secure, and i mean most bicycle locks are remarkably easy to pick or zip open, and with a combination lock i don't need to wear a key.

Thank you dude for that video, I got stuck with my inadvertently setting a random combination which I couldn't remember, and I wasn't able to lock it again! Now I have found the ' lost ' combination 😀 But.....why throw it away?? Use it with an other lock, if someone sees more than one lock it is an additional deterrent! In many cases he will not bother and spend additional time to ' find the correct combination '
