I've changed the Toyota key battery a few times, and it feels pretty easy, especially when doing it yourself—it saves both hassle and money. Just prepare a small flat-head screwdriver, which is usually in the toolbox at home. There are usually small gaps or clips on the key shell; once you find them, gently pry it open with the screwdriver, but don’t use too much force to avoid scratching the plastic or damaging the internal circuit. Inside, you'll see a small round battery, typically the CR2032 model, which is available at supermarkets or online. When removing the old battery, note the positive and negative positions, and align the new battery in the same direction. When closing the shell, press firmly until you hear a click, indicating it's properly secured. Finally, test the remote lock and unlock functions—a red light means it’s working. It's recommended to check the battery life every year or two to avoid sudden failure while driving. Changing the battery yourself also adds a bit of car knowledge, which is quite fun. The whole process takes just a few minutes, and with more practice, you won’t feel nervous at all.
