This is a resettable lock (not a combination lock [which requires you to enter a certain combination]) instead, this lock has a code that can be changed anytime (as long as the device is unlocked). This is the first time I made a resettable lock, it took me a couple to tries to get it right. This is my first post, please like, don't dislike; and if you spot/find/encounter any bugs/problems, please post a comment below with some details about the problem, (This design is not yet perfected). And THANK YOU. (Please download)

*NOTE: Might be laggy for older computers or netbooks.

***(Update) : Fixed Lock problem (You can unlock the code 12 even if you typed 123). Now fixed.
