Root Explanation

Keyless → It is formed from "key" (from Old English *cæg*, meaning a device used to open locks) and "-less" (meaning without). The word "keyless" means without a key, typically referring to a system or device that does not require a physical key for operation.

Memory Tip

Think of being 'without' ('-less') a 'key' — that's what keyless means.
