Start by going to the store and getting your battery. I decided to replace both my fobs at once.

Start by pinching the two tabs on the ring to separate the two sides.

Use a screw driver on the other end to separate both sides of the fob.

Pull out the old battery and slide in the new one and your done!

It’s pretty simple, I had a little trouble separating the sides the second time so I used the screwdriver. First set came apart easily by hand. As well this is where your spare key is located. I’ve had to use it only once when my battery died before.
