A motor vehicle door lock has a rotary latch with a holding recess formed in it. The rotary latch has a main catch with a catch surface formed on it. A key collar has a pin that is adapted to be received in the holding recess. A pivotally mounted detent pawl is biased in an engagement direction and has a catch lever having an opposing catch surface formed on it which is adapted to engage the catch surface of the main catch in a catch position. The catch lever and a support lever are pivotally mounted on an axle to pivot with respect to one another about an axis in the catch position in which the detent pawl is biased by a spring element into an extended position. An actuating element is disposed on the rotary latch, and the spring element cooperates with the actuating element to bias the detent pawl into the extended position when said actuating element engages the spring element. The rotary latch executes an overstroke when the motor vehicle door closes, and the spring element biases the detent pawl into the extended position prior to or during the overstroke.
