Abstract

Motor vehicle door lock or the like with a pivotally mounted locking catch (3), a pivotally mounted pawl (4) which blocks the locking catch (3) in a preliminary locking position and a main locking position, and with a locking mechanism (5) for operating the locking catch (3) and pawl (4). The locking mechanism (5) has an outside release lever (6), and when outside release lever (6) is operated, pawl (4) can swing into a release position freeing locking catch (3), e.g., by being lifted. The manipulation of the lock is improved since, in the opening movement, when the locking catch (3) is in the main locking position and the release lever (6) is operated, the pawl (4) is swung into the release position, where it is retained independently of the further operation condition of outside release lever (6) until the locking catch (3) has passed the preliminary locking position.
