Reasons for sudden car remote key failure include a dead battery or poor battery contact; malfunction of the time control module in the remote key; aging of the car's remote transmitter antenna, etc. Solutions for remote key failure: Replace the car remote key battery; use the hidden mechanical key inside the remote key to open the door; replace the car's remote transmitter antenna; visit a repair shop or 4S store for inspection and repair. Signs of a dying battery: Remote range: For example, if you could unlock the car from five or six meters away before, now you may need to stand right next to the door to unlock it. Occasional failure: For instance, if pressing the button once used to open the door, now it may take two or three presses. Indicator light on the car key: If the indicator light on the car key becomes dimmer or flickers. Some higher-end models may display a warning on the dashboard indicating that the battery is about to die. A remote key allows you to unlock and lock the car from a distance without inserting the key into the lock. Its biggest advantage is that, regardless of day or night, you can conveniently unlock and lock the car from a distance without needing to locate the keyhole. The working principle involves emitting a weak radio wave from the key, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the locking or unlocking action. The system mainly consists of a transmitter and a receiver.

Can a Used Car Be Transferred Along with Its License Plate?

Used cars cannot be transferred along with their license plates, as license plates are not transferable. When vehicle ownership is transferred, the license plate will be revoked. If the driver has owned the vehicle for more than three years, the license plate can be retained for six months when the vehicle ownership is transferred. In cases where the registered ownership of a motor vehicle is transferred, the current driver of the vehicle must apply for a transfer registration at the local vehicle management office within 30 days from the date of vehicle delivery. Legal Basis: Article 52 of the "Regulations on the Registration of Motor Vehicles" states that after completing the transfer or cancellation registration of a motor vehicle, the original owner may apply to the vehicle management office to use the original license plate number when registering a newly purchased motor vehicle. The application to use the original license plate number must meet the following conditions: The application must be submitted within six months after completing the transfer or cancellation registration; the original owner must have owned the vehicle for more than three years; and all traffic violations and accident liabilities related to the original vehicle must be resolved.

What are the differences between car body types?
