What does the key symbol on the car dashboard mean?

[VonPenelope]

The key symbol displayed on the car dashboard indicates that the vehicle is not detecting the car key. This could be due to damage in the car's receiver or transmitter module, or the key battery might be depleted. Many vehicles are equipped with a keyless start system, which eliminates the need to use the car key once inside the vehicle. After entering, simply press the brake pedal and push the start button to ignite the engine. The remote car key contains a battery that typically lasts two to three years. If the battery is dead, it needs to be replaced. Cars with keyless start systems have a designated key fob detection area inside the vehicle. If the key battery is dead, placing the key in this detection area allows the car to recognize the key, enabling normal engine start-up. It is advisable to replace the battery immediately if it runs out of power.
