What Are the Causes of BYD One-Key Start Failure?

[OscarMarie]

BYD one-key start failure is caused by issues such as a dead smart key battery or the gear not being in the P position. The specific details are as follows: Dead Smart Key Battery: When the smart key battery is dead, the key's transmission power is very low, making it difficult for the car's sensor to detect it. Gear Not in P Position: For automatic transmission vehicles (AT, CVT, AMT), manufacturers specify in the manual that the gear must be in the P position when starting the engine. Steering Wheel Locked: After the car is turned off, if the steering wheel is rotated a certain degree from the centered position in one direction, it will make a "click" sound and lock. In this locked state, the one-key start function will not work.
