Why are these holes there? They are certainly not there to make it easier for thieves to break into the lock. But do you know what they are for?

Surely this isn't what it's for, right...

The answer is actually quite simple: It’s just a drain hole . The thing is, these locks are usually used to lock outdoor gates, which means they have to be exposed to the sun and rain.

Without them, rainwater would collect inside the lock, causing it to rust quickly. Not to mention, in Western countries with cold winters, water freezing inside the lock could cause irreparable damage. The only option is to break the lock.
