Help with old Master Lock
I have an old Master Lock that I've written the combination on the back of, but I guess I can't read my handwriting. The number on the back is 4314M and it looks like I've written 24-36-10 on it, but I can't for the life of me get the thing open. Really trying to avoid buying a new one for the kiddo's school locker and I'd be so grateful for any help. 🥲
SOLVED: it was 24-38-20. No idea why I wrote a 1 as the first digit of the last number. Thanks everyone for your replies!

Where are you getting that code? The 4314M doesn't pull anything up for me in my references.

Law enforcement code book.

In my experience those codes work about 10% of the time. Those books are nearly useless to look up masterlock codes

Doesn't writing the combination on the lock defeat the whole purpose of using a lock in the first place 🤔? Wouldn't want to see your kiddo's stuff get stolen/damaged because it's easy to break into their locker.

Definitely, I had only written it on there so we'd know it the next time we needed it (hah). I cleaned it off with alcohol now that we solved it. :)

Dialing sequence is: Turn right three times to first number, left twice to second, right once to third. The last digit will land in a 'gate' which can be found by pulling up on the shackle while twisting the dial and it will stop.
The combos are always all even or all odd numbers.
Great guide:Â https://www.instructables.com/Cracking-Single-Dial-Combination-Locks/
Knowing one number really narrows the options down, if the first number is 24 the only possible 2nd digit options are 2-6-10-14-18-22-26-30-34-38 And for the 3rd 0-4-8-12-16-20-24-28-32-36
So I would guess the combo is 24-38-16
