Why does the key light keep flashing on the car?
2 Answers
Here are the reasons why the car key keeps flashing: 1. Battery: The key's battery is dead. 2. Key: The key is not within the working range or placed in a hard-to-detect location inside the vehicle. 3. Manufacturer key: There is another manufacturer's key similar to yours within the working range. 4. Switch position: The key is taken outside the vehicle with all doors closed while the ignition switch is in the OFF position. Below is additional information about car smart keys: 1. Functions of car smart keys: Car smart keys can emit infrared signals to open one or two doors, the trunk, and the fuel filler cap, and can also operate the car's windows and sunroof. 2. Automatic opening: More advanced smart keys resemble a credit card. When the driver touches the door handle, the central locking control system activates and emits a wireless query signal. The smart key card responds correctly, and the car lock automatically opens.
I've been driving for over 20 years, and when the key indicator light flashes, I know there's a problem. The most common issue is the key battery running low - you need to replace it quickly, otherwise one day the car won't start, which is a real hassle. Check if the key has been dropped or gotten wet, as cracks in the casing can also cause weak signals. Other possible causes include anti-theft system malfunctions or a dirty key chip - try cleaning it yourself first. If that doesn't work, you'll need to visit a repair shop for professional tool reset and reprogramming. This isn't something to delay - safety comes first.
