hey guys I’m kind of new to these forums I’m just looking for information yesterday my 2015 Honda Civic key fob said it needed a new battery went and got a battery it all of a sudden does not work. please help. I’ve taken apart the entire thing I’ve switched batteries in and out we have a second fob and it doesn’t appear anything is loose or missing and that works fine. what could be the problem ??
