Security lock light

Car won't start and key fob for unlocking or starting is not responding. Changed the key fob battery and the car battery. Car went dead after we moved it and had several days of rain. Security light is blinking. Unhooked and rehooked the battery. Did some of fuses but manual does not specifically state which one is security neither does the fuse cover under the hood. It's a push button start so not sure which position is the off or on position and the blinking green doesn't seem to have a pattern.
