Trumpchi GS4 key battery replacement tutorial/method is as follows: 1. On the back of the remote battery, press the button in the direction indicated by the arrow and pull the mechanical key outward. 2. The mechanical key can open the car door when the smart key is out of power, but it cannot start the engine. 3. After removing the mechanical key, you can open the remote key by using your fingernail along the gap on the side of the remote key, which is not complicated. 4. Once opened, you can see the battery compartment on the back cover. Remove the old battery as instructed, replace it with a new one, then close the back cover and reassemble the key.

Replacing the GS4 key is actually quite simple. Just prepare a CR2032 coin cell battery and a small flathead screwdriver. The key casing usually has clips, so gently pry it open from the side gap, avoiding excessive force to prevent scratches. Once opened, you'll see the battery compartment. Use a plastic tool or toothpick to gently lift out the old battery—avoid metal tools to prevent short circuits. When installing the new battery, pay attention to the polarity, with the printed side facing up and aligned with the slot. After inserting the battery, align the cover and press it back into place until you hear a click. I always test the unlock button's responsiveness after each replacement. Here’s a handy tip: If the remote control range shortens, it means the battery is nearly depleted. Preparing a new battery in advance is much better than scrambling at the last minute.

Having replaced the GS4 key myself several times, I've learned the key is boldness paired with meticulousness. First, locate the seam along the key's edge and gently pry open the casing using an expired bank card. Inside lies a square battery compartment—gently push the old battery out from its side. When inserting the new CR2032 battery, ensure the positive side faces upward (the side with metal springs should face downward). After replacement, press the cover firmly to ensure a snug fit and prevent future water ingress. I recommend purchasing branded batteries, as inferior ones tend to leak and corrode the contacts. I always keep two spare batteries in my car; when the remote fails, it's a five-minute fix.

Replacing the key involves four steps: First, prepare a CR2032 battery and small tools; second, pry open the shell along the side gap of the key; third, remove the old battery and replace it with a new one, ensuring the positive side faces up; finally, press the back cover firmly to complete the process. The entire procedure takes just two minutes, saving both time and money compared to visiting a 4S shop. Handle the key gently during disassembly and avoid using excessive force to prevent damaging the internal circuits. A common issue is inserting the battery in reverse, which causes the remote to malfunction—simply reinstall it correctly. The batteries are widely available in supermarkets, costing around three to five yuan each.

Last week, I helped my neighbor replace the GS4 key fob and noticed two different shell designs. For the older model, you can simply pry it open from the bottom, while the newer version requires locating the side clips. When removing the old battery, remember its orientation, and ensure the + symbol faces upward when installing the new CR2032. After closing the cover, don't rush to the car—first test the remote control range nearby to confirm it's back to normal. Some friends mentioned difficulty snapping the battery cover back on, which is often due to misaligned slots. Applying pressure with your fingertips at the four corners makes it easier.

Three key points to note during the replacement process: Use non-metallic shims to prevent short circuits; the model must be CR2032; align the printed side toward yourself when installing the battery. The key fob casing consists of two halves - it's best to cushion with a soft cloth when prying to protect the paint. After installation, press firmly on the center of the key for the most secure fit. Typically, one battery lasts two years, but high summer temperatures can shorten its lifespan. I recommend checking the remote response speed every six months - replace the battery if responsiveness slows. Store spare batteries in dry conditions to avoid moisture damage.
