Child lock stuck

The child lock on my Toyota Tundra 2018 model stuck on both rear doors.
In the position downward and it won't move upward.

I would suppose it should be moving to "unlock" state up fairly easily.

Has anybody experienced it ? (And what's the remedy)

 

Try to move it while locking and unlocking the door with the key fob.
Odd that it is stuck on both doors.

As well.
Child lock part starts at 6:00..
His was stuck and he lubed it up..

Welcome to the forum..

 

Thank you.

The solution from the video would be plan B )..
I refuse to believe that to unlock those latches one would need to dismantle the whole door to the core.

The locks weren’t used and look pretty new.
Still hope there should be some combination with which they can be unlocked.
