I just replaced the battery in my Corolla key last month, and it was actually quite simple. First, you need to buy a button battery—Toyota cars generally use the CR2032 model, which you can find at convenience stores. Use a small screwdriver or a thin tool to gently pry open the key at the thin seam on the back. Be careful not to use too much force to avoid damaging the casing—I scratched mine last time because I was in a hurry. When removing the old battery, pay attention to the orientation, and insert the new one the same way. Finally, close the back cover and press the buttons a few times to test it. If the small red light on the key flashes, you’re good to go. The whole process takes about ten minutes—much easier than going to the dealership and saves you over a hundred bucks in labor costs!
