If the remote control of a remote-controlled car doesn't respond, the first step is to check if the batteries are dead. If so, replacing the batteries should solve the issue. If the batteries are fine but the remote still doesn't work, it might indicate a malfunction in either the car or the remote control, requiring professional repair. Below is relevant information about the "hold" button on car keys: 1. Introduction: Pressing and holding the "hold" button for a few seconds opens the trunk, preventing accidental activation while the vehicle is in motion, hence the name "hold." 2. Additional Function: The "hold" button is not just for opening the trunk; it also serves as a remote engine start button. When pressed for 2 to 3 seconds within a certain range, the car will start automatically. This feature is particularly useful in winter and summer for pre-adjusting the interior temperature.
