I'm not sure I could even fit my wrist in there if I had no hands. It's extremely tight. And getting a screwdriver in there and turning it to lift the tab seems pretty much impossible. Did others remove anything else to get access?

Also, is disconnecting the battery necessary, or is it sufficient to just keep the wires away from the terminal? I did it last night, but it was sparking as the trunk light was on, and it seemed more risky than not touching it at all.
If you can't reach your hand in there are tools you can use to unclip. I have pretty big hands and I managed to unbolt the reservoir and move it out of the way. I think I rotated the hose out of the way as well.
