i'm having a problem with the key fob. i usually have to press it several times before it actually locks/unlocks now. at first, i thought it was the batteries...but i've changed that, and it's still the same. i haven't talked to the dealer yet, but does anyone know if it's goin to need to be replaced? and will it be expensive? and it's 2001 btw, so its outta warranty by now i believe.
