Abstract

A latchable door lock for motor vehicles, whose catch element, in addition to be blocked by a locking pawl to be actuated manually, is to be blocked by a further latching element, whose blocking action can be lifted only by means of a fitting key; the further latching element thereby engages directly at the catch element without reaction on the locking pawl while the key-controlled commands are transmitted by way of lines to servo devices coordinated to the remaining doors and/or flaps and displacing the additional latching elements.
