Since you have the metal part of the key, you can order the pushbutton remote part and have the dealer swap out the metal key and program the remote.

Sunset Porsche in Beaverton Oregon has the remotes on sale for about $95. They usually sell most parts for cost plus 15% and might not have to pay sales tax since Oregon doesn't have sales tax.

When you get the remote, have your local dealer program it for you. Take all of your keys with you when you go to the dealer. Unfortunately it will probably cost more for the 1 hour of tech time at your local dealer than what the remote cost.

At least this way you know you are getting the correct remote for your money.

Good luck!
