Why Can't I Lock the Car with the Remote?

[DelJulianna]

Reasons why the remote cannot lock the car: 1. If you are using the 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; 2. There is strong magnetic signal interference around the car. Since the smart key uses low-intensity radio waves, it cannot function properly under magnetic interference. The car smart key is a common keyless entry system, also known as the smart key system, which consists of a transmitter, a remote central lock control module, a driving authorization system control module, three receivers, and related wiring harnesses. The remote control and transmitter are integrated into the car key, and the vehicle can enter a locked or unlocked state based on the signals sent by the smart key, and can even automatically close the windows and sunroof.
