The pin tumbler lock (or Yale lock, after lock manufacturers Yale) is a lock mechanism that uses pins of varying lengths to prevent the lock from opening without the correct key. Pin tumblers are most commonly employed in cylinder locks, but may also be found in tubular pin tumbler locks (also known as radial locks).

Famous quotes containing the words pin and/or lock:
“What pursuit is more elegant than that of collecting the ignominies of our nature and transfixing them for show, each on the bright pin of a polished phrase?”
—Logan Pearsall Smith (1865–1946)
“Time, which shows so vacant, indivisible, and divine in its coming, is slit and peddled into trifles and tatters. A door is to be painted, a lock to be repaired. I want wood, or oil, or meal, or salt; the house smokes, or I have a headache; then the tax; and an affair to be transacted with a man without heart or brains; and the stinging recollection of an injurious or very awkward word,—these eat up the hours.”
—Ralph Waldo Emerson (1803–1882)
