Happy birthday!

Missing 3 locks. I have 2 unused keys, but not sure if I'm being stupid and missing the obvious, or these 2 are meant to be not obvious to use.

Ok I guess I will give it a try in free time :> 2 locks insta unlocked ;)

I can't even unlock the first lock, I guess I'm missing something obvious :S
Edit: And I also couldn't figure out how to use the keykeykey-key that I found.

Tired of keys and pictures? Head here for a truly challenging puzzle!

Found 15 keys used 13 of them.Annnd figured out what to do but still dont know how :)

Still missing 2 keys :/

So now we're just bumping each other's thread?

You can't say i didn't give your puzzle any chances.
I opened a lock, got some confusing shit as an answer, and now i'm gonna quit.
Thanks for the generosity anyway.

If you don't tell me the solutions, I'm going to start bumping your competition.

You have no choice now!

Missing locks: 2,7,12,17 D: 3 days of tries.

I'm missing one kay.. I mean key.. like everybody I suppose? but guess what, I DON'T EVEN CARE, hah take that ;)

Bumping here to bump my thread!

Last key, come here! I have sweets for you... :3 Come here!

If you guys are getting bored here, there's a new hint on my puzzle

Bump :)

Not that it matters, since I solved it differently, but is the output of Lock 13 correct? It just gets scrambled, but all the other locks (that I unlocked) worked... :/

Still stuck on locks #4 and #14.

bump for finding half the keys

Dammit, still missing the key for lock 12...

Thank you for the very clear solutions, and very nice job, it was an awesome puzzle, with very good ideas :) (@Kappei too ^^)
And very nice drawings (<3 the tortoise :p)

Somehow I thought 'Tortoise Embryo' would play some significant part here :).
Very nice puzzle from you two!
I got completely stumped by DNA sequence (couldn't think simple), heh. Well and didn't find some other stuff.

You made a typo :P
For lock 11 the key is "sfgk"

I managed to brute force (or rather, by powerful and tiresome observation I managed to "piece" together the various QR codes using the corners and edges which matched) the rest of the QR codes whose locks I couldn't open (QR 2, 7, 9, 13; yea I managed to find the key for 12 but not the obvious one on your profile :p )

But I can't seem to understand "dropped in a comment to kappei in the last character", is the comment on a previous thread?

Nice puzzle anyway :) The first puzzle I attempted to solve and almost solved it (got all QR codes, but only a few hours before the giveaways ended so didn't manage to continue to the last step)
