What Causes the Driver's Door to Not Lock?

[MasonLynn]

Here are the specific reasons why the driver's door may not lock: Key malfunction: If you are using a remote key to lock the door, it is likely that the remote lock is malfunctioning or factors such as 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. Magnetic interference: If there is strong magnetic signal interference around the car, the smart key, which uses low-intensity radio waves, may not function properly under such conditions. Door jammer: If the car frequently fails to lock remotely in a certain location, you should be wary of a door jammer. Some criminals use a radio signal blocker that can emit electromagnetic waves at the same frequency as the car's locking signal, thereby blocking the electronic code of the car's central locking system and temporarily disabling it.
