I have a 2015 Sierra SLT that at times won’t allow me to unlock the tailgate with the key.
iT always happens when I need to get into it the most.
I purchased the truck used at the Chevy dealer and they tore it apart and fixed it while it was still under warranty.
Does not seem to be a long term fix. It’s very frustrating when it happens!
Im presently leaving the tailgate unlocked to not have it unusable.
Anyone else have this problem, and if so what have you done to fix it?
Any help greatly appreciated.
