I looked at one at Bob Turner Ford in ABQ in October..
The key looks like a metal tube with prongs sticking out along it. It looked flimsy, as if sitting on it would bend it.
They did not even have a way to duplicate the key! Only 2 keys are provided with the purchase of new one. Should you lose one of the keys, just how can you get a 2nd one made, especially if the dealer himself can't duplicate it?
