In some car models, the horn sound is turned on by default when the car is locked, but there are some ways to turn it off. Different car models may have different methods of operation, and here are some methods that may apply:
1.Set it up via the Control Panel.
Some models may have a setting option in the control panel to turn off the horn sound when the car is locked. You can consult your vehicle's owner's manual or use the resources to learn how to access these setting options.
2.Adjust the sensitivity of the door switch button.
Some models may allow you to adjust the sensitivity of the door switch buttons. If the horn sound when the car is locked is triggered by the door switch button, then you can adjust the sensitivity of the button so that it no longer triggers the horn sound.
3.Disable the alarm system.
If you can't find a way to turn off the horn sound when your car is locked, you can consider disabling your vehicle's alarm system. This can be achieved by disconnecting the power cord from the alarm system or removing the alarm. However, be aware that this may reduce the safety of the vehicle.
4.Adjust the sound trigger conditions.
Some models may allow you to adjust the trigger conditions for the horn sound when the car is locked. For example, you can set it to trigger only when a key is pressed or a button is pressed, rather than when the door is closed.
It is important to note that turning off the horn sound when locking the car may affect the safety of the vehicle. So, make sure you understand your vehicle and its safety features before trying anything, and proceed with caution.
