ELI5:Why does a car door get stuck if the driver unlocks the door at the same time that the passenger is trying to open it?

There's a latch that connects the door handle to the actual opening mechanism.  When the door is locked the latch is disconnected.  If you lift the door handle when unlocking the latch doesn't engage.
