What to Do When the Car Doors Automatically Lock with the Engine Running?

If the car doors automatically lock with the engine still running, it is necessary to contact a professional locksmith or service station personnel to unlock the doors. The purpose of the auto-locking feature is to prevent theft. It quickly locks the doors after driving starts, providing a certain level of security by preventing door-pulling robberies during traffic jams or while waiting at red lights. It also protects child passengers inside the car, preventing young children from opening the door handles while the vehicle is in motion. When the car reaches a preset speed, the lock button automatically engages to prevent accidental door opening. This feature is a common auto-locking method used in many car models. For manual transmission vehicles, the auto-locking setup method is as follows: 1. Turn the ignition switch to the ON position; 2. Within 20 seconds, press and hold the electric door lock switch to the LOCK position for 5 seconds; 3. If the operation is successful, the hazard warning lights will flash, indicating that the setup is complete.
I remember the same thing happened to me last month—the car was left running at the supermarket entrance, and the doors locked themselves. I panicked a bit at first, but then I calmed down and remembered there was a spare key in the trunk. I quickly tried unlocking it. If that hadn’t worked, I would’ve immediately called the 4S dealership or the vehicle brand’s customer service—they can usually unlock it remotely. I’ve made it a habit now to always put the keys in my pocket before parking and never leave them in the car. If you ever forget your keys, don’t force breaking the window—it can easily cause injury or lead to expensive repairs. Regularly check your car’s sensor settings to prevent accidental auto-locking. Prevention is key—buy a keychain reminder or set an alarm on your phone to check your keys.
I usually study vehicle technology, and the automatic door lock may malfunction due to sensor failure or interference. If the car is locked while still running, immediately try using the mobile app to connect and control the unlocking—many brands support this feature. If you don’t have the app, contact the manufacturer’s technical support. Keep a spare key in the office or at a friend’s place—don’t rely on keeping it in the car. Analyzing the cause: it could be due to a low battery in the smart key or system delay causing incorrect signals. For the future, consider upgrading the software or testing system functions to save time and hassle. Develop the habit of removing the key before turning off the engine.
