I'm wondering if I should order a second fob. A couple of weeks after getting my brand new 2000 BMW 323i, I lost one of the keys. I think it was priced about the same as the one for the 3. On the rare times that my wife drives my car she uses her keycard (one of four I have). I have three fobs for my Nissan Murano; one for each driver in the house. One I got with the car, the other two I picked up from Nissan parts department. I think they were around $80 apiece. Two fobs came with the wife's Honda Ridgeline; she has her's and I have mine. I don't think my daughter has ever driven the truck by herself.
I tell myself that I should do my part to contribute to Tesla's bottom line.... Decisions, decisions....
