Are the methods of hacking locks on the internet videos true?

Question

After watching videos on the internet (YouTube) on opening locks using a piece of a pop can, and sliding it into the shackle. I decided to try it myself. It looked so easy in the video, but I was unable to get the lock open even when I am precise at doing things. Are these real methods or are they like sort of set up? Other than picking or bumping, do you know a way of hacking locks, I need one of my combination lock opened?

Answer 1

Yes, shims are a real method of opening locks, however a simple pop can shim probably won't open a good, quality lock. If you actually need to get the lock off of something, as opposed to getting the lock open so you can reuse it, I recommend a good set of bolt cutters.
