Not sure I just bought the car.It does not say anything about Pontiac though so possibly. But it looks legit. It has the same Start image as the actual key hole does. (A little arrow going in a circle)

EDIT: What if it is an after market one? I see it has to be programmed, but wouldn't that make it not work at all? Everything works expect the remote start.

Mine looks just like this one:
