Well not as great as I thought. First I had to file the edges of the button holes because the buttons were too stiff and would not return on their own. Then I dropped it and it stopped working. Took it apart and it seems there is no retention system to prevent the the electronic board from sliding out of place losing contact with the battery terminals. Going to see if I can glue it in place. Sucks having a fancy new key and have to ask the wife to open the hatch for me with hers.
