How Do Locks Work?

💡 Simple Explanation

Inside a lock are little metal pins stacked in twos. When no key is in, the pins block the lock from turning. Your special key has bumps and dips that are just the right heights to push each pair of pins to exactly the right spot - like a secret handshake! When all pins line up perfectly, the lock can turn. A different key has different bumps, so it pushes the pins to wrong spots and the lock stays stuck. Your key is the only one that knows the secret!
