k5 key battery replacement steps are: 1. Remove the mechanical key; 2. Insert the mechanical key into the keyhole to pry open the key shell; 3. Open the remote key's cover plate to remove the old battery; 4. Install the new battery and close the key cover. Taking the 2020 K5 as an example, its body dimensions are: length 4980 mm, width 1860 mm, height 1445 mm, with a wheelbase of 2900 mm. The 2020 K5 is equipped with a 1.5T turbocharged engine, with a maximum power of 125 kW and a maximum torque of 2653 N·m, paired with a 7-speed dual-clutch transmission.

I used to change the battery for my Kia K5 key fob myself—it was a breeze. There's a small gap on the side of the key; just gently pry open the cover with a small screwdriver or a coin. Inside, you'll find a small round CR2032 battery. When removing the old battery, don't be too rough. When inserting the new one, make sure the positive side (marked with a + sign) faces upward. Press the cover firmly until you hear a click to ensure it's locked. After replacing, quickly test the key buttons to see if they lock/unlock the doors. The whole process takes just a few minutes—much faster than going to a dealership and saves you money too. I recommend checking the battery every year and a half, and when buying a new one, go for a reputable brand for better durability.

My family also uses a Kia K5, and I've replaced the key battery twice. First, observe the small groove on the side of the key—that's where you open the cover. Use a thin object like a coin or nail clipper to pry open the shell. When removing the old CR2032 battery, be careful not to damage the metal contacts. Insert the new battery with the positive side facing up. When reassembling the cover, press it tightly to prevent water or dust from entering. After replacing, test the buttons immediately to ensure they respond normally. For safety, keep your hands clean and dry, and avoid doing this in rainy weather. If the key is several years old and the battery drains quickly, it's a good idea to keep a spare battery at home just in case. The process is simple but requires patience.
