What is the reason when the driver's door is unlocked but cannot be opened?

[StPatrick]

This issue is most likely caused by a malfunction in the driver's side door lock and requires prompt attention at a 4S shop for repair. Below are other possible reasons why the door may not open despite being unlocked: 1. Water on the door handle sensor area: Vehicle door handles use capacitive sensors, and water can create capacitive noise that interferes with the antenna's detection, causing it to enter a self-protection mode where the sensitivity of unlocking and locking decreases. In severe cases, the unlocking/locking function may temporarily become unusable. 2. Rain impact during wet weather: Under heavy rain, the door handle's capacitive sensor continuously detects changes in capacitance. To avoid false triggering, the door handle antenna enters a rain mode, which extends the locking response time and reduces the sensitivity of unlocking and locking detection.
