First, I move all keys, cell phones, etc at least 5 feet away from the outside of the car before starting the procedure. Then, I turn the car to IG ON (not running) and hook up the programming cable and connect with Techstream. I'm able to automatically pull the VIN and model info, so I know that is working.
Next, I go to the Smart Access programming section in TS, and choose the option to register a new key. It gives me a detailed rundown of the process before I start.
Then, I start the programming procedure. Within 30 seconds, I touch the old key to the car's start button, and the car beeps as expected. Then, I move the old key away from the car and bring over the new card, and also touch it to the start button, and again the car beeps like it should.
The last part is where it all goes wrong. TS tells me to put the new card on the passenger seat to complete the programming. I do this, and the process times out without actually finishing.

I have tried repeating this with the car in ACC mode, as well as with the car completely off. Nothing so far has worked, and it always fails at the last step where I am told to put the new key on the passenger seat.

Help! What am I doing wrong?
