What's wrong with the red light on the car key?
First of all, the car key can turn on the red light, which proves that the car key has electricity. There are several possible reasons:
1. Normal phenomenon. On some models, when you press the exit key, it turns red. For example, Azeri 5.
2. If the car key is red, the car can't start, and even the dashboard doesn't light up, which means the battery of the car is dead. It is very likely that the headlights were not turned off when the car was locked on the first day, resulting in the battery being dead. In this case, replacing the battery can solve the problem.
3. If it is a red backlight, it can be determined that it is something dyed red.
If the key can't be used normally, it is suggested to drive with the mechanical key first, and drive to a 4S shop or a professional garage for technicians to check and see what causes it. Find out the problem and solve it.
