How do you replace a Toyota Highlander key battery?

Is there an easy way to replace a Toyota Highlander key battery? I've been having some problems with mine, and I think the battery's dying. I'd like to try changing it, but I don't really know how to.

To replace a Toyota Highlander key battery, you should start by purchasing a CR2032 battery—it only costs about $5.00. Once you have your new battery, follow these steps:
  • Step 1: Pry off the rear cover with a flathead screwdriver or another and remove the remote control.
  • Step 2: Loosen the clips holding the circuit board in place.
  • Step 3: Gently lift the circuit board to reveal the old battery.
  • Step 4: Replace the old battery with the new one and reassemble the keyfob.
  • Step 5: Test the key! If it doesn’t work, adjust the battery’s position and try again. If it still doesn’t work, then
    your problem may not be battery-related
