The fobs I have bought, both FP and factory, have a square tag rather than that rectangular one. Is this style recent?It's authentic, style 92078.
What's wrong with the tag?
ETA: They look more like this one:

ETA: I just saw another one listed with a similar tag, so I guess they aren't all the same.
