A device for captivating a variety of fasteners relative to a first member. A captivator includes a body adapted to be secured to the first member and a retainer received within the body and having a surface engaging a captured fastener. Together the body and retainer maintain the captivated fastener in place relative to the first member. Keyway surfaces are provided upon the body or retainer or both and an external or internal key engages the keyway surfaces to selectively lock the body and retainer together, such as during installation or replacement of the captured fastener. Upon removal of the key, the retainer is free to rotate and translate relative to the body.
