What's the situation when the Volkswagen Golf suddenly can't lock the doors?

[McMelanie]

The reasons why the Volkswagen Golf suddenly can't lock the doors are as follows: Remote lock failure: If you are using the remote key to lock the doors, it is very likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter is aging, causing the remote key to not work. In this case, you can use the spare mechanical key to lock the doors. Magnetic field around the car: Another situation is that 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. Door jammer: If the car frequently fails to lock remotely in a certain place, the owner needs to be wary of a door jammer. Some criminals use a radio signal blocker that can emit electromagnetic waves of the same frequency as the car's locking signal, thereby blocking the electronic code of the car's central lock and causing it to temporarily malfunction.
