Abstract General consideration of the present invention is to provide a device which would prevent the unauthorized opening of an automobile trunk lock without the use of a key. The device is fashioned to conform to various automobile trunk lock designs. The device offers protection by incasing the vulnerable areas of the lock, which if disturbed could result in the trunk''s opening thus defeating the lock''s purpose. The device is readily and economically fabricated from sturdy and durable material. The device requires no special care and no special knowledge for use by the user.
