Why Can't the Car Door Be Locked?

[MacMason]

Here are the reasons why the car door cannot be locked: 1. If you are using the remote key to lock the door, it is very likely that the remote lock is malfunctioning or factors such as the aging of the car's remote transmitter antenna are causing the remote key to not work. In this case, you can use the spare mechanical key to lock the door. 2. There is strong magnetic field signal interference around the car. Since the smart key uses low-intensity radio waves, it cannot function properly under magnetic interference. 3. If you frequently encounter situations where the remote lock does not work in a certain place, then the owner needs to be wary of door signal jammers, as some criminals use a radio signal jammer that can emit electromagnetic waves of the same frequency as the car lock signal, thereby blocking the electronic code of the car's central lock and temporarily disabling it.
