Can a Keyless Start Car Automatically Shut Off When the Driver Leaves?

[SophiaDella]

Keyless start cars cannot automatically shut off after the owner leaves. Below are specific reasons why the key may not be detected: 1. Weak battery: For cars with batteries older than 2 years or those parked for extended periods, you can check the battery's condition using a multimeter. Typically, the voltage should be around 12V when not in use and above 10V during ignition to rule out battery issues. 2. Poor fuse contact: Lightly tap the fuse box. If the car starts, it indicates poor fuse contact. 3. Starter motor failure: If the battery has power but no sound is heard from the starter motor when pressing the ignition button, it may be a starter motor issue, requiring replacement at a repair shop.
