parked my car for three weeks.
when i open my door, both front door dome lights flashes crazy fast.
also, there's also a circuit clicking sound, crazy fast...
similar sound to when you power door unlocks...
but it could be a circuit/switch clicking non stop?
when i close my door, this stops.

car won't start.
when i try, it won't crank at all.

alarm light stays solid red or flashes when i open the door, forgot the detail pattern...

my battery i think is 9 years old, im not the first owner so I'm not sure...
I am going to bring it for testing and buy a new one first to see if it'll fix the issue.
anyone seen this quick blinking light symptoms?

 

I think you might have chased down the source, the battery.

 

I found post mentioning that the 2004 G35 Coupe should have a Group 35 battery.
mine is showing 24, I probably need the same one?
