This has only started to occur within the last two days and only is an issue in the morning after my car has sat outside overnight.

The fact that once the car heats up the key fob has no issue makes me think it is an issue internal to the car and not the key fob.

The key fob even works from an extended distance so it doesn't seem like it is a issue with the battery within the key fob (I've also only had the car since September '16 so I would think the key fob battery would last longer than that).

> Might be electronic interference. I have a 2008 OB that, when remote started but sometimes just sitting off as well, will give me trouble opening the doors but will open eventually after I keep pressing the button for a time. I read Subaru added defenses against hacking where the receiver shuts down briefly if it detects excess signals. I think these remotes operate on 433 which would put them in the CDMA band I think. Cell phones and/or maybe WiFi could be part of the reason. My car specifically also seems to maybe have a tracker in it as I can detect a signal coming from it using a cheap scanner I got, comes from around the front passenger side and only active when the engine is running. Probably left over from previous owner or dealer since I got it used and with only one fob, meaning it might have been a repo.

At home there are dozens of other people who all have cellphones and wifi in a small area triggering the car's defenses. At work, there is practically nothing. By the sounds of it you park it outside so maybe in a parking lot away from most electronic signals, right? That would explain why it works one place but not at home. Just my theory on the matter though. Still could be a bad part in internally too but warranty should cover it. Not sure if it's still valid after 3 years though.
