To use the buttons inside the fridge (for temp control, etc), you have to push the “unlock keys” button for 3 seconds. This isn’t a nuclear missile launcher, it’s a fridge. Idiots.
You’d appreciate that if you had dumb kids who enjoy nothing more than pushing buttons just to hear them beep. (And then you come back and wonder why your freezer is set at 60F and your fridge is set at -20F…) In theory, any kid smart enough to figure out the ‘unlock keys’ button should also be smart enough that you can instruct them to not fuck with the fridge controls.
