I tried disconnecting the car battery trick, put new 2032 battery in FOB and still the fob will only work intermittently on the back doors but will not lock or unlock , sometimes the rear will open and one sliding door( passenger). I did buy 2 new FOBS a couple years ago and had dealer program them but neither is working correctly. Could it be the FOBS or is ther something else and how would I find out? Thanks in advance, advice greatly appreciated.

 

I really need help with this, is there some module that needs replacing? I've tried all suggestions, please help!
