Bought one online for the '06 2500 we had that turned out to be junk. Broke apart on my wife after a few months and the free replacement did the same thing. Might consider spending a few dollars more for a factory key.
Also learned that lesson with the wife's '16 Challenger fob. Bought one online that looked just like a factory fob but for 1/4 the price. Buttons worked fine but you had to use the end of the fob to push the start button and then leave the fob in the console. If you didn't, you would get the "key has left vehicle" message. Made sure we got 2 factory keys w/ the '17.
