2015 Suburban Door Locks
 

Hello! I'm new here. OK, I have a 2015 Suburban. The three passenger doors will not respond to the fob and they will not respond to the driver's side manual lock button. I've had a few mechanic look at this and nobody can figure it out. Has anyone had this issue? The driver's door and the hatch will unlock with the fob, but the manual button does nothing at all.

Thank you in advance!
