What to Do When BYD S6 Cannot Detect the Key
1 Answers
There are mainly three reasons why the BYD S6 experiences the "key not detected" issue: 1. The key cannot receive or send signals; 2. The vehicle cannot receive or send signals; 3. Both the key and the vehicle can receive and send signals normally, but there is an internal transmission issue. Specific manifestations include: 1. Poor key placement: For example, inside the trunk, on the car floor, in the cup holder, in the glove compartment, on the door panel storage box, near the rear storage panel, or under the front windshield; 2. Low key battery: The remote key typically uses a standard coin-cell battery with a rated working voltage of around 3.3V, and under normal conditions, its lifespan can reach up to 2 years. 3. Signal interference: Placing the key near devices like mobile phones, laptops, or power adapters; 4. Key chip malfunction, leading to poor or no signal transmission; 5. Faulty in-car oscillator or related issues, resulting in the failure to form an effective electronic oscillation zone, thus unable to scan and recognize the key; 6. Antenna issues in the rear window glass, causing signal reception failure. Check if the antenna signal amplifier is working properly or if window tinting is blocking the signal; 7. Deviation in the vehicle's signal code rate, requiring reloading of the key and vehicle matching codes; 8. Internal malfunction of the CAS (Convenient Access and Start) system.
