What are the reasons why the BYD S6 cannot detect the key?

[VanIsaac]

BYD S6 cannot detect the key for the following reasons: 1. The key is placed in an inconspicuous location, such as inside the trunk, on the car floor, near the rear storage panel, or below the front windshield. Try placing the key in a more visible location. 2. The key battery is low. The remote key typically uses a standard button battery with a rated working voltage of around 3.3V. Under normal circumstances, the battery lifespan can generally last up to 2 years. 3. The use of a key case may weaken or block the signal. 4. There is an issue with the key chip, resulting in poor or no signal transmission. 5. The car's oscillator itself or related faults may prevent the formation of an effective electronic oscillation zone, thereby failing to scan and recognize the key.
