Thanks for the feedback. I paid $75 to a local locksmith for a
transponder key and for them to cut and program it. They had to throw
the first one that they cut in the trash because it could not even
open the door.

I am guessing I now have two master keys, correct? If I loose one of
them then I can always get another one made for about $80.

I will probably get a key fob from eBay and program it myself which I
hear is not too difficult as long as I'm relatively athletic and
patient.
