How do I change the battery in the car key for my Toyota?

For the past week, I’ve been getting a notification on my Toyota’s display telling me that my car key battery is low. I’ve never put in a new one before. What’s the process to install a new battery in a Toyota remote?

If you got your vehicle new, it is common for your car key fob to need a battery change after about three or four years. If you bought your car used, however, you may need to replace your battery much sooner.
Either way, to change the battery in the car key for your
Toyota
, just follow these simple steps:
  1. Purchase the correct battery for your car key fob. If you aren’t sure, check your owner’s manual.
  2. Press the metal button at the top of the key fob to release the manual key inside.
  3. Pry the key fob open with a flathead screwdriver.
  4. Remove the circuit board. Do this carefully to avoid damaging any of the small components.
  5. Remove the old battery and put the new one in its place.
  6. Press the key fob back together and return the manual key to its housing.
Once your car key battery has been replaced, take a moment to check out the
