1. Any chance you have 2 key fobs? Is the issue reproducible with both fobs(is available)? If the issue is reproducible with both fobs- key fobs are not the issue. If you only have 1 fob- any chance your local parts stores have keyfob tester(it is a sensor that you put your keyfob next to and press any button. It will show you the signal strength which usually is indicative of battery health. In your case keyfob battery is new, so it will show you if the fob is capable of strong signal. ). This device can be alternative purchased on ebay for about $20 and can show you accurate frequency reading , etc.
2. When this issue started or you bought this car like that?
3. Any chance you are seeing fluid leak like picture in your rearview mirror?
