We are traveling back from Georgia and would like oir vehicle to be left at the airport by my brother in law? What is the procedure for pick up?

SFO long term parking is $25 / 24 hours.

I would try to save some money and park at an off site airport parking lot or just pay more and park in long term parking at the airport

What she said, but i will add that its insanely expensive but there are 2 parking lots and the one farther away is much cheaper although still insanely expensive.

Park the vehicle at SFO Int'l Airport, long-term parking lot, ask brother in law for the keys and car location, no brainer

Ok, thanks for the tip... But the part I really want to know about is there a place where the keys are dropped off. @Angel Gabriel Loya ...Not really a no brainer if you haven't done it before
