    Default Key Fob Battery Replacement

    Members don't see this ad
    The battery in the key fob for my 2009 3.8 Genesis seems to be dying. I have to stand closer to the car to be able to open the door than I did a month or two ago.

    Has anyone replaced the battery in their key fob? There is no obvious way to open it and I want to avoid damaging it. I assume it uses some type of watch battery for power.

    Page 4-10 of the owners manual states:
    " 1. Pry open the rear cover of the smart key. 2. Replace the battery with a new battery (CR2032)."

    I saw that as well, but it provides no directions or diagrams on how to pry off the cover. The fob is not made of especially hard plastic and I'd rather not leave large, unsightly screw driver marks. I suppose it's a matter of inserting a slotted screw driver in the seam between the two halves of the fob and prying but has anyone actually done this yet?

    I tried to pry it open with a flat head screw driver just for the heck of it when I was playing with the idea of removing the H logo and replacing it with the wing badge.
    Wouldn't budge.
    Just left a nice scratch on the fob.
    Anyone finds an easier way to open it, I'd be glad to know.

    I never noticed it before, that there is no slot for a coin or screwdriver. When I go to change mine out, I will use a sharp knife, in the crease between the two halves.

    There are two squire slots on both side of the fob.
    I tried a flat head screw driver that was exactly the same as the diagonal opening and turned it clockwise to see if it does the trick.

    I used a plastic tool kit made to repair small electronics such as Blackberry, Iphone. It comes with a plastic pic like a guitar pic which worked great.

    There is a notch under the trunk key that you can put a screwdriver in and open the fob. The trunk key can also be used to open the fob in a pinch but it is likely to cause the marring you are trying to aviod. Another thing I noticed is if you take the battey out of the fob and stick it in the slot in the console the car will still start. Good news if your fob battery completely dies.

    The notches in the side are for the slot in the console

    I thought pushing the key fob into that slot just below the disc drive charges the battery, or at least that is what the dealer told me

    Wrong- it is just the fob placeholder- no charging.
