When we bought our "girl" she came with 3 keys, two are transponder keys but only one was programmed. The one not programmed looks brand new and I wanted to use it as the working key is cracked and worn.

Today after work I tried the steps found on Rob's website dedicated to the 100 series and it worked just as described!

If you have a key you need it programmed, give this a try!

There is also a lot of neat write-ups and how-to's on this site!
