This is a song from Keys. It's sung by Gabe Sokoloff.
Lyrics[]
When a lock is locked
The space inside is blocked
By a row of pins preventing it from turning (Turning!)
But when the right-shaped key goes in
It neatly lines up every pin
That's how a key unlocks a lock
In a pin tumbler lock (That's the typical kind!)
The plug is the little space inside
And inside that, there's a row of pins
Lined up in pairs, pushed by springs
Blockin' that plug from turnin' free
But if you got the key
That moves each pair to certain height
The space between pairs lines up right
At the shearline (Shearline!)
Now that plug is free to turn
And the end result, you move that bolt
Consider your lock lesson learned
When the lock is locked
The space inside is blocked
By a row of pins preventing it from turning (Turning!)
But when the right-shaped key goes in
It neatly lines up every pin
That's how a key unlocks a lock
