My 2001 does not have a 'lock' button on the power windows - likely because only the front seat occupants have access to the window controls.
Open the door and in the lock itself is a keyhole. Insert your ignition key into the hole in the lock and turn a quarter turn. This will lock the child lock and obviously ,turn in the other direction to unlock. Rory

Take te child lock off of the door
you press the lock button
To unlock the LG LK311 child lock, press and hold the "Child Lock" button for about three seconds until the indicator light turns off. If your model does not have a dedicated child lock button, try pressing and holding the "Settings" or "Menu" button along with the "Start" button for the same duration. Refer to your user manual for specific instructions tailored to your model. Once unlocked, you can use the appliance normally.
Does that lock work using other methods like the button on the door, or keypad/keyfob?If not, it's likely the door lock actuator mechanism is failing.See "Related Questions" below for more
