Why Can't the Car Door Lock?

[KadenRose]

Reasons for car door not locking: remote lock failure, strong magnetic signal interference around the car, shielding of the electronic password of the car's central locking system, etc. Here are the relevant details: Remote lock failure: If you are using a remote key to lock the door, it is likely that the remote lock is malfunctioning or the antenna of the remote transmitter in the car has aged, causing the remote key to not work. In this case, you can use the spare mechanical key to lock the door. Signal interference: Another scenario is the presence of strong magnetic signal interference around the car. Since smart keys use low-intensity radio waves, they cannot function properly under magnetic interference. Electronic password shielding: If the car frequently fails to lock remotely in a particular location, the owner should be wary of door jammers, as some criminals use radio signal jammers that emit electromagnetic waves at the same frequency as the lock signal, thereby shielding the electronic password of the car's central locking system and causing it to temporarily malfunction.
