What does a red key symbol on the car dashboard indicate?

[Wendy]

There are two possible scenarios when a red key symbol appears on the car dashboard: 1. A KEY-labeled symbol indicates insufficient battery power in the car key. It's advisable to promptly inspect and determine whether the battery needs replacement. If the battery is depleted, it should be replaced as soon as possible to avoid inconvenience in vehicle usage. 2. A symbol without the KEY label represents the engine immobilizer indicator. Normally, this light should turn off after the car is started. If it remains illuminated, it may indicate a fault in the anti-theft system, and the vehicle should be inspected at a 4S shop or auto repair facility. Below is relevant information: The purpose of a car anti-theft system is to prevent unauthorized operation of the vehicle and protect valuable items inside. The car anti-theft system primarily consists of electronic control circuits, alarm devices, remote keys, mechanical keys, and actuators.
