2 Answers
To replace the battery in the GAC GS4 car remote key, follow these steps: 1. Press the button on the back of the remote key in the direction indicated by the arrow, then pull the mechanical key outward. 2. After removing the mechanical key, open the gap on the side of the remote key. 3. Remove the old battery as instructed and replace it with a new one. 4. Close the back cover and reassemble the key. Advantages of the remote key: It allows for long-distance unlocking and locking. The car antenna receives the radio signal, which is identified by the electronic control unit (ECU), and the system actuator (motor or electromagnetic coil) performs the unlock/lock operation.
My own Trumpchi GS4 remote key fob ran out of battery, so I replaced it myself—quick and easy. First, pick up the key and locate the small notch or gap on the back. Use a coin or your fingernail to gently pry open the back cover, but don’t use too much force to avoid scratching the plastic. Once open, remove the old battery, which is a CR2032 coin cell—pay attention to the orientation: usually, the side with text facing up is the positive terminal. When buying a new battery, choose a CR2032 brand from a supermarket or hardware store; it only costs a few bucks. Insert the new battery in the correct position, then snap the back cover shut and press firmly. Test the lock/unlock buttons to see if the LED responds. The whole process takes just 2-3 minutes, saving you a trip to the repair shop. I recommend checking the battery life yearly to avoid sudden failure when you’re out. If the key stops working, also check if the contacts are clean—lightly wiping them with a cotton swab might restore functionality.
