A tubular lock is a variation of a pin tumbler lock, where the pins are arranged in a circle facing the front of the lock and are operated by a tubular key. It was once referred to as an ACE lock, with ACE being a trademark of the Chicago Lock Company, but the generic term tubular lock is far more common these days.
