A key with a large portion of the bit filed away so that it can open different locks. Also called passkey.
The term skeleton key is also often used to describe lever lock keys. This usage perhaps stems from such keys' resemblance to a skeletal figure, the lock's hole into which the key is inserted is fashioned in the shape of a circle at the top, with flared lines projecting down from it to form the sides of an isosceles triangle, the circle at the top then circumscribing the triangle at one-third the vertical length of the two sides resembling a stylized skull.
