Multiflex tailgate disable feature

[Slsl123]

I’ve got a 2024 Silverado 2500 Custom with multiflex tailgate.  Does anyone know if the disable/lockout feature for the upper tailgate is included in all builds?  Mine isn’t working and my local dealer was reluctant to try to repair because they weren’t sure if my truck was supposed to have that option.  I thought all trucks with that tailgate had that feature.  Mine even has the decal next to the tailgate.

I'm sure you already tried, but just to make sure, are you holding your key fob right next to the button when holding it for the 7 seconds?

I have not heard of any of those tailgates from 2022 and on not having the disable feature, and that sticker seems like confirmation you have the feature.

Mine needed a software update at the dealer (likely can be done over the air like normal too, not sure) until it worked for my 2022.

Mine didn't work at first, until I placed key fob right next to button.  Hold button until tail lights flash three times. Worked great!

I believe the lockout is only trucks with the keyless entry(buttons on the door handles). To my understanding it doesn't have the antenna in the rear that it would need detect the key.
