What Could Be the Reason When the Car Key Fails to Unlock the Door and Start the Engine?
1 Answers
When the car key fails to unlock the door and start the engine, it could be due to a malfunction in the remote control or radio frequency device, or possibly an issue with the main unit or door control module. Below are two common fault scenarios along with their diagnostic methods and solutions: 1. Remote control or radio frequency device malfunction: If the remote control's battery is dead and none of the other buttons work, the battery needs to be replaced. 2. Main unit or door control module malfunction: If the battery is functional and other buttons on the remote control work (the dashboard not lighting up also indicates an issue with the main unit or door control module), you should call the repair service number provided on the remote control's packaging or user manual.
