Fuel filler door is locked on 2008 Saturn Astra

First time this has happened. Tried unlock button. Is there another latch to open door

look in the trunk behind the fuel door for a pull cable or manual release. some models have it and some do not.
if not, you may have to go to a shop to have them open it for you.

I had to unlock from inside the car by pushing the button to unlock the door. It finally opened, but I did have a friend who had to get hers replaced because it wouldn't open
