The invention discloses a magnet type tight door lock. A magnet is added in a middle lining of a door and is connected with a key socket and a power source, and a magnet is arranged on a corresponding door sill. When a key is not inserted into the socket, the magnet in the middle lining of the door is electrified by virtue of a circuit and attracts the magnet on the door sill to ensure that the door is kept closed; and when the key is inserted into the socket, the circuit is powered off, and the magnet in the middle lining of the door does not have magnetism and cannot attract the magnet on the door sill, so that the door is opened. The magnet type tight door lock disclosed by the invention has the advantage that the tightly locked door can be automatically opened or closed when the key is inserted into the socket, so that the magnet type tight door lock is convenient and practical.
