I just bought a 2012 Citadel. The removable push start button is missing ( have to insert the FOB) and the door handle passive lock/unlock is not working. I have replaced the FOB battery. The dealer checked the door handle and said they don't know why it is not working, but didn't offer to figure it out or get it working. Could these issues be related? What should I be looking for and can you just buy a push button? I can start the engine with the pushbutton on the FOB and do not get a "FOB not detected" when I get in. I get the "press break and push start" so it seems the FOB is transmitting. And I have confirmed in the system setting that PKE is active. Thanks for any help.
