On the back of the remote battery, press the button in the direction indicated by the arrow and pull the mechanical key outward. The mechanical key can be used to open the car door when the smart key runs out of battery, but it cannot start the engine. After removing the mechanical key, you can open the remote key by using your fingernail to pry open the gap on the side of the key—it's not complicated. Once opened, you will see the battery compartment on the back cover. Follow the instructions to remove the old battery and replace it with a new one. Then, close the back cover and reassemble the key. Here is some additional information: Trumpchi GS4: The new GS4 has undergone adjustments and upgrades in its detailed design. The most significant changes to the front face come from the headlights and fog lights, with overall lines appearing more youthful and sporty. The rear changes also focus on the light clusters, with large-sized light strips enhancing the rear's recognizability. The new Trumpchi GS4 still uses the 1.3T and 1.5T engines, with maximum power outputs of 101kW (137PS) and 112kW (152PS), respectively. The transmission options have been upgraded to include a 6-speed manual, 6-speed automatic, and 7-speed dual-clutch.
I've changed the battery for the Trumpchi GS4 key fob several times, and the key is to be careful. Usually, there's a small gap on the back of the key fob. You can gently pry it open with a fingernail or a small screwdriver to remove the back cover. Inside, there's a coin cell battery, typically a CR2032, which you can find at convenience stores or auto parts shops. When removing the old battery, make sure to note the positive and negative orientation. When inserting the new battery, place it with the positive side facing up to avoid reversing it. Press the cover back firmly to ensure a good seal, then test the remote locking function. The whole process takes about five to six minutes and requires simple tools, but avoid using excessive force to prevent cracking the key fob shell. It's a good idea to keep a spare battery at home since the battery usually lasts one to two years—replacing it early can save you the hassle of being unable to lock your car when you're out. If the cover won't open, don't force it—there are detailed video tutorials online you can search for.
I always remind everyone to operate safely when replacing key fob batteries, especially for female friends or beginners. Before starting, ensure the car is parked and turned off to avoid accidental touches. The Trumpchi GS4 key fob back cover usually has a snap-fit design - gently pry it open with your fingernail without using excessive force. The battery inside is a CR2032 type with clearly marked positive/negative positions - don't install it backwards. After installing the new battery, remember to securely close the cover and test the remote response. If it doesn't work, check the battery contacts or polarity alignment. Avoid forcing it open to prevent hand injuries or damaging the key. Safety first! A damaged key can cause major inconvenience, so I recommend using the free battery replacement service at authorized 4S stores for peace of mind. The process is simple but requires patience. Keep spare batteries in your bag to avoid the embarrassment of a dead battery on the road - this habit has saved me many times.
