I recently purchased two transponder keys from eBay. The keys had to be program by a locksmith. I called up Eric from Pop-A-Lock whom I met a few weeks ago at the balloon spectacular, where he had a booth set up.Eric came to my home in program the transponder keys for me. He also offered me a remote for my car at no additional cost.if you are in need for any locksmith services, I highly recommend Pop-a-lock.
