A template for drilling a lock to gain access to a locked enclosure has a drill guide and a dial ring mounted to a key stud. A key blank may be inserted into the key stud, with the portion of the key blank which is insertable into the keyway of a lock extending from the template. The key lank is inserted into the keyway of a lock to position the template on the lock and the drill guide is manipulated to align a mark on the drill guide with a graduation on the dial ring to indicate a desired location for drilling a retainer of the lock.
