ABSTRACT:
An automobile steering lock includes a body member, a housing and a lock means. The locking means is contained in a lock housing in the housing, and consists of a base, plural number buttons, a press button, an adjust plate, plural wheels, a control plate, a press plate, a coil spring and a deadbolt. When the number buttons are all rotated to the preset coded number for unlocking, the press button can be pressed inward to force the press plate together with the deadbolt to move down to the unlocking position to free the housing from the body member. Thus this lock needs no keys, and the coded number is adjustable by a user, preventing the lock from being pried open by thieves.
