When I bought my 06 Screw I was so excited that I didn't notice that the guy only gave me one key. A few days later I realized my mistake. I contacted the guy a number of times but he just gave me the run around and ducked my emails and calls.

Luckily I came across some information that saved me a lot of $$$.

Normally 2 programmed keys are required to program a third key however if you have command start you can use it along with your original key to program another key.

First buy a couple blank 'SA' keys from eBay for around $20 shipped to your door. My 06 came with a 'S' (stamped on the key) 40 bit key, 'SA' keys are 80 bit and are backward compatible. Take them to the dealer to have them cut using the VIN, only $10 at my dealer.

I used the remote start, let it run for a few seconds, tapped the brake to kill the engine. Then put my main key in the ignition, went to the on position for a few seconds, then off. Then I put the new key in and went to on for a few seconds, then I pulled the key out. I put the key back in and it started. I programmed the third key by using the 2 keys (like the factory instructions in the owner's manual call for).

Now I can move on to getting a flip key and/or a programmable key so I can get rid of my command start key fob.

Hope this works some somebody else so they can save $$$ as well.
