I was just at the Lexus dealership for a new key shell because mine's broken. $60 and that includes the new key. I don't really need a new key, and they're trying to tell me that the key shells I can get online don't work well--he says they're cheap (I'm sure), and that sometimes the parts don't fit and they have computer problems. I don't understand why a new, plastic, 3-button key shell after-market couldn't be used--even if it is a cheapo? Is this guy telling me BS? I mean, all there is to it is the battery, the little computer chip, and the key. Can someone please explain? I hate feeling like I'm getting robbed, and I'm hoping to get some more perspective.
