What does a flashing key on the car dashboard mean?

[Blanco]

Car dashboard key flashing indicates that the key cannot be detected. The reasons are: 1. The battery in the key is dead; 2. The key is not within the working range or is placed in a hard-to-detect area inside the car; 3. There is another manufacturer's key similar to the key within the working range; 4. When the ignition switch is turned to the OFF position, the key is taken outside the car and all doors are closed. The maintenance methods for car keys are: 1. Do not frequently place them with metal items; 2. Do not place spare keys on the car door; 3. Prevent smart keys from falling or being hit; 4. Prevent smart keys from being in high-temperature environments or coming into contact with liquids; 5. Do not place keys together with electronic devices.
