Universal key
A universal key is like a magic key that can open many different locks. Imagine you have a bunch of doors with different locks that need to be opened. Instead of carrying around a bunch of keys for each lock, you can just use the universal key to unlock all of them!
The universal key works because it is specially designed to fit into many different types of locks. It has a shape that matches certain parts inside the locks, so when you turn it, it can move those parts and unlock the door.
Some people use universal keys for convenience, like building managers who need to access many different apartments. However, it's important to remember that not everyone should have a universal key because it can be used to break into places that aren't supposed to be accessed. So be careful and only use a universal key if you are authorized to do so!
