Keyless entry doesnt work. Changed batteries still nothing. Tried to reprogram. Won't go into programming mode.
Key fob broke years ago. Finally got around to ordering a new fob but truck won't accept it. Truck does go IN to program mode, but even after holding lock/unlock for up to FIVE Min., still no joy. Is there a way to test the receiver?
MY KEYLESS ENTRY WONT STAY PROGRAMED NEED TO KNOW WHERE SENSOR IS
Key fob would not open or close the back doors. Panel on driver's side would not open passenger window.
