1. A motor vehicle lock for use in a hatch leaf, coupled to a vehicle body, and configured to change between a closed state and an open state, the motor vehicle lock comprising:
a catch configured to engage a lock striker and pivotable about a catch axis;
a pawl including a pawl arm configured to engage the catch and pivotable about a pawl axis,
wherein when the motor vehicle lock changes to the closed state, the catch is in a catch closed position and engages the lock striker, the pawl arm is in a pawl closed position, and the pawl arm engages and blocks the catch,
wherein, when the motor vehicle lock is in the open state, the pawl arm is in a catch open position and releases the catch, the catch is in a catch open position and releases the lock striker; and
a drivetrain including a number of drivetrain components provided with a displaceable drivetrain component, wherein when the drivetrain is in an operating state, each of the drivetrain components engage each other to transmit a driving force from an electric motor to the pawl arm to pivot the pawl arm about the pawl axis from the pawl closed position to a pawl open position,
wherein the displaceable drivetrain component is configured to be directly engaged by an opening tool, wherein the opening tool is configured to be moved along an engagement direction from a disengaged position, in which the opening tool is disengaged from the displaceable drivetrain component, to an engaged position in which the opening tool directly engages the displaceable drivetrain component, wherein the displaceable drivetrain component is configured to be displaced by moving the opening tool from the engaged position along a displacement direction so that the drivetrain changes from the operating state to a service state, wherein the displacement direction and the engagement direction are identical so that the drivetrain changes from the operating state to the service state when the opening tool is engaged with the displaceable drivetrain component, wherein when the drivetrain is in the service state, the drivetrain and the displaceable drivetrain component are separated from the electric motor, and wherein manual rotation of the opening tool, when the drivetrain is in the service state, actuates the displaceable drivetrain component by direct engagement between the displaceable drivetrain component and the opening tool in an actuating direction to actuate the drivetrain, without the electric motor, and to pivot the pawl arm about the pawl axis from the pawl closed position to the pawl open position.
