Is the Inability to Start the Car with a Functional Key Related to the System?

[Heather]

Car key having power but unable to start the car is not related to the system. When the car key has power but shows no response, the possible reasons include the following: 1. Severe signal interference in the surrounding environment; 2. Damage to the key's adjustment unit; 3. Mismatched key code; 4. Dirt inside the key causing poor contact; 5. Being too far away from the car; 6. Issues with the car itself, such as damaged circuit board relays or problems with the car's central control system. Below is more information about car keys: 1. A remote key utilizes the wireless remote control function of the central locking system, allowing doors to be opened and locked from a distance without inserting the key into the lock. 2. The working principle involves the key emitting a weak radio wave, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the locking or unlocking action.
