Hello everyone, I just changed the battery in my generation 2 2016 Chevy Cruze key fob, the one for push button start but now the key fob isn't working. I can't get into the vehicle or do anything with the key fob itself. Do I need to reprogram the key fob once I've replaced the battery? Or did i more than likely damage the circuitry when opening the device? What can I do to regain access to my car? I have no idea how to start it without working keyfob, but I can get access inside with the metal key attached to the key fob. Please can anyone help?
