Well worth the money, only 1 small hiccup.
The only hiccup I had was that the QR code included in the paperwork lead to a dead link. But I was able to search the website and find instructions. Everything worked as described and the process of programming the fob and the key went smoothly and everything works as it should. For about half the cost of a locksmith and about 1/4 the cost of the dealership, it was definitely worth it!
