How do you change the battery in a Toyota Sienna key fob?

I’ve had my Toyota Sienna for a while now and the key fob just stopped working. I think it needs a new battery, but I don’t know how to replace it. What steps should I take to change the battery in my Toyota Sienna key fob?

Answer
Key fobs are now a standard feature in most cars. You’d be hard-pressed to find a newer car without one! Thankfully, it’s easy to change a key fob’s battery. Follow these steps to change the battery in your Toyota Sienna key fob:
  1. Buy a new battery. Most key fobs, including the Toyota Sienna’s, take a CR2032.
  2. Insert a coin in the notch at the top of your key fob and twist it sideways to pull pry open your key.
  3. Slide the old battery out of its slot with either your fingernail or a flathead screwdriver.
  4. Insert your new battery in the same position you found the old one. Use the + and - marks to guide you.
  5. Align the two halves of your key fob and snap it back together.
  6. Test it out!
Hopefully, these steps will make it easy for you to change your key fob battery! Remember, key fob batteries usually last around 3-4 years. So you’ll likely need to change it a few more times.
