For me the FZV antenna failed intermittently at first, and then finally stopped working. To my knowledge there is no way to distinguish between a failed battery and a failed FZV. Even using the PA Soft scanner it couldn't tell that the FZV was bad, it just didn't register the key press signal and couldn't reinitialize the keys. (If you can't initialize a brand new key you would know that the FZV would be bad, albeit after you've already spent the money on a new key.)



There's a guy that rebuilds diamond keys as well, though I wouldn't argue with just biting the bullet and buying a new one.



Just another one of the fun and exciting ways these cars break. Fun and exciting for people who like to fix them, not so much for people who just like their cars to work.
