A child lock is a mechanical or electronic safety latch system integrated into the rear doors of passenger vehicles. When engaged via a small switch on the door edge or a button on the driver's console, it disconnects the interior door handle linkage from the latch mechanism. This ensures the door can only be opened using the exterior handle, preventing accidental opening by children while the vehicle is in motion.
Heard on the job
The customer complained the rear passenger door won't open from the inside, but I just flipped the child lock off and it works fine.
