    After 3 years, both of my key fob batteries failed. (I guess that I was lucky. I have heard some of the batteries failing in only 9-12 months).

    The battery in the key fob is a Panasonic CR2032. I went to Walgreen's and purchased a set of two Energizer batteries for $6.99.

    The replacement steps are very easy (don't go to the dealer):

    1. Remove the valet key by pushing on the slide and pulling it straight out.
    2. Using a thin-bladed screwdriver or a knife edge, unsnap the key fob by
    gently prying around all of the edges.
    3. One the key fob splits apart, simply pull out the old battery and insert the
    new one. (Don't worry, unlike some watches, there are no loose parts
    inside).
    4. Handle the new battery around the edges and push it into place using
    your thumb and index finger (Tip- Use a small piece of paper towel to
    avoid getting any hand oil on the new battery and angle the battery in
    towards the silver retaining clips).
    5. Align the two halves of the key fob and snap them together.
    6. Reinsert your valet key.
    7. Test your locks to insure that they are working.

    You are done (less than 5 minutes)!

    Here are some photos to illustrate the install.

    I just tried to replace my low battery in my 2014 Challenger fob and now the car doesn't even detect the fob. I thought it might be the wrong battery so I put the old one in and it says the same thing. What do I do??

    The new battery is the same, CR2032. Is there something I forgot to do or did wrong? I followed the directions above. With either the old or new battery it says "key fob not detected."

    Now I see my battery was drained from the hood not being closed, most likely. And indicator went from 'fob not detected' to 'defective key'. I'll see what happens after charging battery.

    try taking the button out of the key spot and enter the manually. I know that is what I do every once in a while when mine says that, that start button just pops out , very simple.

    I feel really smart now - I put the battery in upside down. I guess it at least it could be an opportunity to grow in the virtue of humility

    Great info! One of my fobs needs the battery replaced. I was afraid it’d be a hassle. Looks pretty simple! Thanks
