What Causes Automatic Car Door Unlocking?

[DiClaire]

Possible reasons include one of the four doors not being properly closed when locking the car, or the trunk not being fully shut. For most vehicle models, if any door isn't properly closed, the car won't fully lock. Other reasons are as follows: 1. When locking, the doors appear closed and locked but aren't fully secured. In this case, even if the lock button is pressed, the doors won't lock. 2. After locking, other objects in your pocket within the remote's range might accidentally press the unlock button. Many people bundle car keys with other keys, making this scenario quite common. 3. Smart key settings. Some vehicle keys have separate functions for locking only the driver's door or all doors, so it's important to check which function is activated when locking. 4. Due to smart key configuration, which uses advanced RFID technology to automatically lock/unlock doors based on the proximity of the key's smart chip. When the owner approaches within a certain distance, doors automatically unlock; when moving away, they automatically lock.
