The invention discloses a hidden longitudinal locking antitheft door lock locked with a key. The longitudinal locking antitheft door lock locked with the key is that a lock plunger is arranged at a door joint, so that the safety of the antitheft door can be improved; the lock is locked through the key, and thus the phenomenon that the automatic-locking door is not locked after being closed can be avoided. The longitudinal locking antitheft door lock locked with the key is characterized in that a locking point strip is mounted on a door frame; a locking point block on a main locking strip is inserted into a lock body hole in a door leaf after the door is closed; an inclined bolt of a lock body is pressed into and then sprung out to be inserted into a rectangular hole in the locking point block, the door leaf can be fixed in the position, and the door can be operated only after the inclined bolt is contracted; after the door leaf is fixed, a drawing head of a tapered end can be pinched through the key at the inside and outside of the door; a main lock cylinder is inserted into the rectangular hole of the locking point block, and therefore, the safety of the antitheft door can be improved; a bolt can be rotated in the door, a safety lock cylinder extends out to be inserted into the rectangular hole in the locking point block, and thus the door cannot be locked from the outside.
