Polo will lock itself if the doors are not locked. Here is an introduction to Volkswagen: 1. Introduction: Volkswagen is an automobile manufacturing company headquartered in Wolfsburg, Germany, founded by Ferdinand Porsche on March 28, 1937. 2. Brands: The company owns brands such as Audi and Volkswagen. In May 2021, the "2021 Forbes Global 2000" was released, with the Volkswagen Group ranking 17th. 3. Development: On March 28, 2018, Volkswagen officially released the official images of the Atlas-Cross-Sport concept car, which made its global debut at the 2018 New York Auto Show, and the car will also be mass-produced in the United States in the future.

My family drives a Polo, and this car does have the feature of locking itself if you forget to lock the doors. It mainly depends on your car's configuration and settings. When driving, the doors will automatically lock once the speed exceeds about 15 km/h to prevent accidental opening. After parking and turning off the engine, you still need to press the key to lock the car, unless it's a high-end model with keyless entry. I remember one time I forgot to lock the car in the neighborhood, and the next day I found it had locked itself. Later, I learned that this happens when the key is more than 2 meters away from the car, triggering the automatic locking feature. However, this function needs to be enabled in the car's computer system first. Older models without this feature can only be locked manually, so it's best to develop the habit of locking the car and checking the door handles.

I work at an auto shop and have dealt with many Polos. This issue depends on the situation: the doors usually lock automatically while driving, engaging with a click when the speed reaches around 10-20 km/h. After parking and turning off the engine, the factory setting doesn't lock the doors automatically—you need to press the key fob manually. However, newer Polo models equipped with the KESSY system can automatically lock about 30 seconds after the owner walks away with the key beyond 1.5 meters. The key is whether this feature was selected when purchasing the car—you can check the vehicle settings on the central control screen. If you often forget to lock the car, you can buy an OBD auto window closer on Taobao to achieve walk-away locking.

My colleague's Polo just had this issue last week. In the morning, he found the car mysteriously locked, and the mechanic said it was due to the keyless entry feature. The high-end Polo can automatically unlock when the key is nearby, and if you don't manually lock it when leaving, it will lock itself after about half a minute. However, older Polo models without keys definitely don't have this capability—they can only be locked manually. Reminder: don’t rush off after parking; turn back and check if the turn signals flash—flashing means it’s truly locked. Pay extra attention on rainy days, as automatic locking with windows not fully closed could lead to wet interiors.

From a design principle perspective, the Polo's automatic locking after parking relies on the smart key system. When you close the door and walk away with the key, the vehicle's sensors will activate the protection mechanism if they no longer detect the key signal. However, this feature has certain conditions: the walk-away auto-lock option must be enabled in the settings beforehand, the key fob battery must have power, and all doors must be properly closed. If you frequently visit shopping malls, be aware that signal interference in some areas might affect the automatic locking. For true convenience, it's recommended to develop the muscle memory of pressing the key fob to lock the car.

I bought a new Polo last year and specifically studied the manual. For the version with keyless entry, it does automatically lock if you don't lock it after parking. The operation is simple: get out of the car, close the door, and away without touching the key button. The car will flash its lights twice and beep, indicating it's in the ready-to-lock state. When the key is out of the sensing range (about 2 meters), it will lock itself in about 30 seconds. However, during testing, I found that if the trunk is open, it won't lock, and it also won't lock if any door isn't closed properly. For the lower-spec Polo without this feature, you have to lock it manually. It's recommended to set the automatic door lock when exceeding speed for added safety as soon as you get in the car.
