Turnkey → The word is formed from "turn" (from Old English "turnian", meaning to rotate or change position) and "key" (from Old English "cæg", meaning a device for opening a lock). Together, it refers to a complete solution or service that is ready for immediate use, as if one only needs to turn a key to start using it.
Imagine having a solution that is ready to use, just like turning a key to unlock a door — that's what 'turnkey' means.
