How do you turn off child safetey lock on a 2000 mountaineer?

To turn off the child safety lock on a 2000 Mercury Mountaineer, locate the child safety lock switch on the edge of the rear doors. Use a key or a flathead screwdriver to turn the lock mechanism from the "Lock" position to the "Unlock" position. Make sure to do this for both rear doors if needed. Once done, the child safety locks will be disabled, allowing the doors to be opened from the inside.
