Playing around with some of the cylinder locks that come with my cheaper knock off cages I’ve found that they can all be unlocked incredibly easily with just about anything small enough to fit into the key hole. Is there an actual lock available that can’t be opened by anything and everything. One that the correct key is absolutely required to unlock?
Burg Wachter. (Spelling questionable) sells a much better quality lock, in my opinion. Keyed differently than the Chinese locks most use. You could always just use JB Weld. ♂️
