smells like a lemon.. does it taste like a lemon?
Well, I've just replaced one of my smartkeys recently (it didnt start acting up until perhaps November, after nearly 2 yrs of use). seems some of the early smartkeys have problems.
-shorted out rear glass defroster (fixd)
-exterior bulbs keep burning out
-central vent keeps fogging up the windshield (replaced... still a bit left)
-clicking driver's seat (fixed.. but now there's some "give" when going around corners.. bah i give up)
