What Causes the Car Key Light to Flash?

[IsabellaLee]

The reasons for the car key light flashing include a malfunction in the key's transmission module or the remote key being out of control range. Specific causes and solutions are as follows: Malfunction in the key's transmission module: If the car key light on the dashboard is flashing, it means the car cannot detect the key, which may be due to a malfunction in the key's transmission module. The solution is to have the key repaired. Remote key out of control range: The car key light flashing usually occurs when the remote key leaves the control range while the vehicle is not turned off or fully powered down, such as being more than 0.8 meters away from the car. In this case, the vehicle's anti-theft system activates, which is a normal phenomenon.
