What does it mean when the key light flashes on the car?

[OEmily]

When the 'key' light flashes on your car, it indicates that the key cannot be detected. If this light stays on or flashes, it means the car's computer is not receiving the signal from the car key, and the engine's anti-theft system is not deactivated, preventing the car from starting. Below are the possible reasons and solutions for this situation: 1. It could be due to a dead battery in the key or a damaged receiver module in the car. You should try to avoid remote control from a long distance during normal use. 2. Here are the solutions: (1) Try placing the key near the ignition switch. If that doesn't work, you can take it to a repair shop or a professional institution or 4S store for diagnosis. (2) If it's just a dead battery in the key, replacing the battery should solve the issue. Additional information: This situation usually occurs in vehicles with a push-button start because the engine cannot properly receive and detect the key data when starting the vehicle without turning the key, triggering the warning.
