2002 Suburban Passlock problem

I know this isnt a mopar problem, but it is a problem for this mopar lady.

My main transportation for taking hubby to doctor is the 2002 Suburban.
As of 2 days ago, the passlock light came on and I can no longer start the car.

I have 3 weeks to solve the problem before I have to take him to another doctor appointment.

I do not have the original key fobs or original keys.
I have two replacement keys made a few years ago.

I've researched this problem to death on the web but I'd like some...
