I've replaced the battery for my Trumpchi GS4's electronic key several times myself, and it feels really easy. First, you need to buy a new battery, usually the CR2032 model, which costs just a few bucks at a battery store or online. Then, there's a small gap on the back of the key. Use a plastic tool or an old bank card to gently pry open the cover—don't use too much force to avoid cracking it. Inside, there's a small battery that can be easily popped out with a light push. Insert the new battery, making sure the positive side faces up to avoid reversing it. Close the cover tightly and press the remote buttons to check if the indicator light turns on. If it lights up, it's working fine. I recommend replacing the battery once a year before winter, as cold temperatures drain the battery faster. If the battery dies, you won't even be able to open the car door, which can be really frustrating. Also, avoid leaving the key in direct sunlight to extend the battery's lifespan. If it still doesn't work after replacement, the cover might not be properly secured—just reassemble it once more.

I'm just starting to learn how to drive and I'm afraid of damaging my Trumpchi key fob when replacing the battery for the first time. Actually, the steps are simple: prepare a CR2032 battery, which you can buy at a pharmacy or store. The key fob has a small latch or seam, carefully pry it open with a fingernail or small screwdriver to avoid scratching the plastic casing. Remove the old battery without touching the internal circuit board to prevent static electricity, then insert the new battery with the plus side facing up. Press the cover firmly and test the unlock button to see if the car doors respond. If you're unsure, ask a friend for help or visit a repair shop—it only costs a few dozen yuan, saving you from fumbling around. Before replacing, it's best to read the manual or check the model online to avoid buying the wrong battery and wasting effort. The battery typically lasts about a year; replace it when the indicator light dims to prevent awkward situations when heading out.

The key to replacing the key battery lies in tool preparation: I went to the supermarket and bought a new CR2032 battery for about one yuan. Locate the gap on the Trumpchi GS4 key and gently pry open the shell with a plastic card. Remove the old battery inside, replace it with the new one, ensuring it lies flat with the positive side facing up. Close the cover tightly and test the button functions. If it doesn't work, the contacts might be oxidized—just wipe them. To prevent battery drain, avoid leaving the key in high-temperature areas inside the car. It's a simple matter of a few minutes; no need to spend money on professionals.
