battery dead, door carrier broken, locked out

[Marine6531]

Gents I'm looking for some help here. Recent snow storm caused my handle to freeze up. when i pulled on it the door carrier broke (Ive replaced this before so I'm familiar with this). I was leaving for vacation 2 days later and didnt get to fix it. So today i get back from vacation and go to unlock my car and get in from passenger side to open drive side and truck chirps "weirdly" and locks all the doors. and now it doesn't make any sounds. so im assuming my battery died.I can manually unlock the driver door but cant open from outside because of carrier. so i need some help to...

1. open hood from outside so i can jump car?

2. "jump" from starter cable enough to unlock doors (is this even possible? starter accessible?)

3. use screwdriver etc to get door carrier to open?

I have also read there is a "secret" way to get in but it can only be told through PM. I would greatly appreciate that info if available too. If anyone has any other ideas please let me know.
