I remember the time I changed the battery for my Teana key was quite smooth. There's a small gap on the back of the key, so I just used a coin to gently pry it open, revealing a round CR2032 battery inside. After taking out the old one, I replaced it with a new battery, making sure the positive side with the plus sign was facing up, then pressed the cover back on. Testing the remote, both locking and unlocking worked perfectly. The whole process took just a few minutes, no need to spend money at a repair shop. I usually pay attention to signs of the key running out of battery, like the remote range getting shorter or responses becoming sluggish, so I take action in advance to avoid sudden failures. Plus, you can easily buy this type of battery at supermarkets or online for about ten yuan. I often keep one or two in my handbag, so I don’t panic if the battery dies while I’m out. The key design is quite user-friendly—doing it yourself isn’t complicated at all, and you even pick up a little skill.
