2018 Sierra child lock always on

[Cryssyl]

Just recently I’ve started to notice that the child lock on my 2018 GMC Sierra is always on, even though I never put it on and the light on the button is off. I have to press the button twice, once to turn it on and again to turn it off for the back doors to be able to open. I have 2 kids but they are 11 and 14. I haven’t ever had to use it and definitely don’t need it now lol. Anyone got some tips or tricks? Don’t really want to have to bring it in

Welcome to the site.

 

I know it will revert back to the last setting that was used. Just a guess, turn it off (the switch) with the engine running, drivers door closed, then shut off engine, take key out, open drivers door, step outside, close door. Then see what happens when you enter the truck again.
