I bought a 2006 Audi A4 from an auction 2 weeks ago. It's in great shape and only has 35000 miles on it. The problem is it only came with one key, no owner's manual, and the buttons on the key remote doesn't work. I took it into the dealership, and they're wanting to charge me $150 to program the remote to work. Also, I wanted to get another key and they said that would be $350!

Are there other options? Could I program the remote on the key myself?

Thank you.
