How to Replace the Battery in a Sonata 8 Key?
2 Answers
Sonata 8 key battery replacement method is: 1. Remove the metal key from inside the key fob; 2. Pry open the key fob shell through the gap at the tail end; 3. Take out the old battery; 4. Install the new battery by reversing the steps. Taking the 2020 Sonata DCT Leading Edition as an example, it is a mid-size 4-door 5-seater sedan with body dimensions of: length 4955mm, width 1860mm, height 1445mm, and wheelbase of 2890mm. The 2020 Sonata DCT Leading Edition is equipped with a 1.5T engine and a 7-speed dual-clutch transmission, with a maximum power of 125 kW and a maximum torque of 253 N·m.
Changing the battery for the Sonata 8th generation key is actually quite simple, and you can do it yourself in just a few minutes. Prepare a CR2032 button battery, and find a thin pry tool or a slim nail file. Carefully observe the key casing—there's usually a thin seam in the middle. Gently pry it open with the tool, but avoid using excessive force to prevent damaging the clips. Once opened, you'll see a small circuit board and the battery, which is held in place by a metal tab. Use your fingernail or a small tweezer to lift the tab and remove the old battery. Insert the new battery in the same orientation, positive side up, until you hear a 'click' indicating it's secured. When reassembling the casing, make sure the parts are aligned before pressing them together. After replacing, test whether the buttons and indicator light work. I recommend laying a towel on your work surface beforehand to prevent small parts from rolling away and getting lost.
