09 bags popped. How to make it drive?

Hi. I have a beat, tired 04. Neighbor hit my driver's doors and I am getting P0A10 battery code. (Unrelated). Plus various other glitches. But I am attached to this tired old beast. Looking at an 09 with lower miles hard hit on same 2 doors. He bought new doors then realized the B pillar was too bad to mount straight doors on. I can fix that. I have torches, welder and bfh fine alignment tools. But the left head bags are popped and he says the car can not be driven since the accident. How does one reset that issue?

 

First off I want to test drive the car, hear engine, check batt, etc. Later I will consider repairing it complete as opposed to parting it out.
