The button on the door handle is the control center of the smart key system, primarily responsible for the following core functions:
Door Control Interaction
Keyless Unlock: When approaching the vehicle within 1-1.5 meters with the smart key, the system automatically unlocks the doors. Simply press the button to unlock (no need to remove the key).
Convenient Locking: After turning off the engine and exiting the vehicle, pressing the button directly locks the doors, improving efficiency by over 60% compared to traditional key operation.
Intelligent Safety Protection
• Automatic Compensation Locking: If the vehicle is not actively locked within 3-5 meters, the system will automatically execute the safety locking procedure.
• Dual-Mode Linkage: In addition to touch sensing, some models feature a press-type + slide-in dual trigger mechanism.
Troubleshooting Strategy
When the button response is abnormal, prioritize checking the following:
Key Battery (CR2032 button battery recommended for annual replacement)
Main Battery Voltage (must maintain a static voltage above 12.3V)
Sensor Module Operating Status (cross-verified through passenger door testing)
