hey weasel, i drive and hour to and from work every day. plus plenty of trips here and there during the day, but sometimes i have to press the unlock or lock button on my key a few times before it actually opens or locks. today i was outside the bank and i was standing on the passengers side and it took about a minute before the doors would unlock. whats up with that? i dont get it. do i need a new key? or a battery?....thanks
