Why does my phone alert me about abnormal door opening?

When the car door is not properly closed and you attempt to lock the vehicle, you will receive an alarm notification if someone tries to open the door without unlocking it. Below is relevant information about car doors: 1. Introduction: Car doors provide entry and exit for drivers and passengers while isolating external disturbances. They offer some protection against side impacts and enhance passenger safety. The aesthetic appeal of a vehicle is also influenced by door design. The quality of car doors is primarily reflected in their anti-collision performance, sealing capability, and ease of opening/closing. Anti-collision performance is particularly crucial because during side impacts, the buffer distance is extremely short, making occupants vulnerable to injury. 2. Classification: Car doors can be categorized into front-hinged doors, rear-hinged doors, sliding doors, gull-wing doors, and folding doors.

Last time my car also had this kind of false alarm. That time my parents were helping me carry things, and the elderly are used to gently closing the door, which triggered the phone's beeping alarm. This kind of smart reminder is actually very sensitive; the door not being closed properly or the lock catching a leaf can set it off. Most of the time, it's just the door not being shut tight, especially on rainy days when the rubber seal is slippery and prone to bouncing back. I suggest you try locking the car remotely first. If the app still reports an error, then you'll need to get in the car to check. Problems with the electronic lock module are the most annoying. Once after a car wash, a short circuit caused the alarm to go off repeatedly for three days before I found out that the trunk wiring harness had been loosened by the high-pressure water gun. Now, whenever I get a warning, I always pull the door to confirm first before checking the app logs.

I often encounter this situation with my Tesla. Nowadays, many cars use electronic signals to control door locks, and sometimes the system fails to receive the signal, resulting in false alarms. For example, have you ever parked in an underground garage? Concrete walls can weaken Bluetooth signal strength, causing the system to fail to detect that the door is properly closed even when it is. I recommend restarting the vehicle's system or updating the app version. After the last OTA update, my false alarm rate dropped significantly. If this happens frequently, it's advisable to check the BCM (Body Control Module), which acts like a butler managing all the vehicle's electrical communications. By the way, it's important to set a complex password for the remote unlocking feature. My neighbor once fell victim to a hacker's prank because their password was too simple.

Sounds like a sensor haunting. Last time my car had cola spilled by a naughty kid, the door lock sensor got sticky and caused the system to go crazy. Modern cars rely on micro switches to detect door lock positions, which can fail with just a bit of dust or grease. You can try pressing the rubber cover near the lock catch yourself—if the spring plate gets stuck, it can also trigger abnormal alerts. Be extra careful with cars that have kick-sensing trunk opening; once I accidentally brushed a delivery box against the undercarriage sensor, and my phone suddenly showed the tailgate open for half an hour. Keep spare keys at least three meters away from the car—some models' wireless keys can continuously interfere with signals if left too close.
