Solutions for car key not working after battery replacement: 1. Re-synchronize the key by opening the driver's side window while keeping other windows closed; 2. Insert the remote key, turn to position II, then quickly return to position 0, repeat this process 4 times; 3. Quickly remove the key, press any button (like unlock) for 4-5 seconds until hearing a beep from inside the car, indicating successful key coding. This smart key can emit infrared signals to open one or two doors, trunk, and fuel filler cap, and can also control car windows and sunroof. More advanced smart keys resemble credit cards - when the driver touches the door handle, the central locking system activates and sends a wireless query signal.
