How to Disassemble the JAC Refine S3 Car Key?
2 Answers
To disassemble the JAC Refine S3 car key, you can either pull the key apart with force from both sides or use a screwdriver to pry it open. Insert the screwdriver into the gap inside the key, then manually separate the part with the circuit board and the part with the battery from the middle of the key's circuit board. After separation, carefully remove the battery from the panel to fully disassemble the car key. The remote key utilizes the wireless remote control function of the central locking system, allowing you to unlock and lock the doors from a distance without inserting the key into the lock. In simple terms, the working principle involves the key emitting a weak radio wave, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator performs the locking or unlocking action. Once the key is awakened, it analyzes the authentication command sent by the car and transmits the corresponding signal, which is encrypted to enhance security.
I've previously disassembled the JAC Refine S3 car key, and the process was quite straightforward. There's a small groove on the side of the key—use a flathead screwdriver to gently pry it open, starting from the edge. Be careful not to apply too much force to avoid cracking the plastic. Once opened, you'll find a coin-cell battery inside, model CR2032. Just replace it with a new one. If the buttons malfunction, it might be due to dirt or loose connections—cleaning the contacts often solves the issue. Take your time during disassembly; the key's back cover clips are fragile and can easily snap if pried incorrectly. I recommend taking photos before disassembling to avoid confusion during reassembly. This method works for most domestic car keys, saving you a trip to the repair shop. Just use a common household screwdriver for the job.
