What Are the Reasons Why the Car Lock Won't Open and the Key Won't Turn?

The reason is that there is an issue with the vehicle's central control system. The central control system is managed by the vehicle's onboard computer. In this case, it is necessary to contact the after-sales service department of the 4S dealership to inspect the vehicle, reset the onboard computer, and check and resolve the central control system issues. Below are solutions to related problems: 1. The matched vehicle key cannot be used: This occurs because only the vehicle key was matched without including the chip. Modern vehicles have chips in each key, and a key without the chip will not function. Most vehicles with keys lacking chips can only unlock the car doors and have no other functions. Pay close attention to this during key matching. 2. All vehicle keys are lost: You can provide valid vehicle-related documents and contact the after-sales service department of the 4S dealership where the vehicle was purchased to have new keys matched by the vehicle manufacturer. It is crucial to keep the vehicle keys safe, as matching keys without the original ones can be very troublesome.
