What does it mean when the key light flashes?
1 Answers
The reason why the key light flashes is: there is a fault in the contact switch inside the key head or the battery is dead. The method to replace the car key battery is: 1. Remove the mechanical key; 2. Insert a flat-head screwdriver into the bottom "open" position and pry it up and down; 3. Once a gap appears, use the screwdriver to pry open the key along the gap; 4. Take out the old battery and replace it with a new one; 5. Assemble the key. The working principle of the car key is: a weak radio wave is emitted from the owner, received by the car antenna, and after the electronic controller identifies the signal code, the actuator of the system performs the action of unlocking or locking. The functions of the car key are: 1. Remote locking and unlocking of the door; 2. Press and hold the lock button after turning off the engine to close the windows; 3. Press the horn-shaped button to locate the car.
