Locate the fixing screw on the key and remove it with a screwdriver. Find the opening notch on the side of the key, and use your hand to pry open the seam along the side from the notch. Once opened, you can see the inner core of the key; slowly remove the key core. On the chip, you will see the battery. Use a screwdriver to pry out the battery and dispose of the old battery properly. Replace it with a new battery and reassemble the key in the reverse order of the above steps. Visit a car 4S shop or a local authorized car electrical repair shop to have the battery replaced by a professional technician.
Replacing the battery of a Hanteng X5 key is quite simple, and I've done it several times for friends. Usually, there's a small gap or clip on the key shell, which you can gently pry open with a coin or fingernail—just don't use too much force to avoid cracking the plastic. The battery is typically a CR2032 model; make sure to buy a reputable brand, available at supermarkets or online. Once opened, you'll see a small circular battery—pay attention to the polarity (positive side facing up or down, depending on the markings) to avoid installing it backward. After removing the old battery, insert the new one, press the cover back on, and listen for a click to confirm it's secured. After replacing the battery, test the unlocking function. If the car doesn't respond, the key may need reprogramming. The whole process takes about 5 minutes. Key batteries usually last 1-2 years, so replace them in time to avoid failure at critical moments. Opting for original batteries ensures longer life and saves repair hassles. Avoid exposing the key to high temperatures to extend its lifespan.
