Why doesn't the car beep when locked?

[AvaFitz]

The reasons why the car doesn't beep when locked are as follows: 1. The car key malfunctions. 2. Silent mode is activated. When silent mode is on, only the headlights flash when locking, without any audible alert. 3. The beeper for the alert sound is damaged. If the vehicle still doesn't produce the alert sound after pressing the mute button, it indicates that the beeper is damaged. Here are some precautions to note when locking the car: 1. You can use the mechanical key to lock the car. When using the mechanical lock, ensure all doors are properly closed and listen for the sound of all doors locking; otherwise, the car isn't successfully locked. 2. When using the electronic lock, observe whether the lights turn on after locking and if the car emits a locking sound. 3. After locking, pull the door handle again to check if the doors are securely locked.
