linchpin or lynchpin (LINCH-pin) - n., a locking pin inserted in the end of an axle to prevent a wheel or other part from slipping off; something that holds the various elements of a complicated structure together.

Dates to the 14th century, earlier form linspin (and that shift from /s/ to /ch/ gets commented on as odd), from lins, axel (from Old English lynis, axel) + pin. The figurative extension dates to the early 20th century.
