Replacement of Dodge Challenger Key Fob Battery

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.

 

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.
