Will the car automatically lock if the key is left inside?

[DaisyDella]

Whether the car will automatically lock when the key is left inside can be divided into the following three scenarios: 1. "Keyless Entry": For models equipped only with "Keyless Entry" functionality, the car can detect the presence of the key inside and the onboard computer will prevent automatic locking. 2. Automatic Locking: Many vehicles feature an automatic locking function when the doors are closed. For example, even lower-end BYD models have a 30-second auto-lock feature, which can sometimes be inconvenient. These functions can be enabled or disabled via the diagnostic computer at authorized service centers. 3. Without "Keyless Entry": For models without "Keyless Entry" functionality, if the vehicle is turned off and the doors are closed without the key, both the doors and the trunk will automatically lock after a few minutes.
