2003 Saturn Ion anti-theft stopped blinking, Remote Keyless Entry stopped working, won't start

What is your question?

Noticed Anti-theft​ was not blinking on dash, after a thunderstorm. Keyless entry, with key FOB wouldn't work, when I noticed & attempted to investigate, Used key to open driver side door. Attempted to start car—it wouldn't start. Locked door manually. Then, a symbol, NOT flashing (??-Perhaps a lock symbol?) appeared on dash. Then, I used key to unlock, tried to start car, it would not. Manually locked car, the symbol still there. 5 days later, NO lit SYMBOL on dash, I unlocked with key, tried to start, NO GO. Can't open trunk even with "pop button" & key won't open trunk either! Gonna try to jump car off under hood, & try "trunk pop button" again, bc actual battery in trunk. But WHY won't my key work in trunk lock? Is it possible that when I had ignition recall fixed, did my key suddenly stop working in trunk lock???

What makes this problem better or worse?
