Why does the car key not work after replacing the battery?
1 Answers
Car key not working after battery replacement is due to remote key failure, requiring re-pairing after battery replacement. Below are the specific steps for key pairing: 1. Insert the remote key, turn to the "II" position, then quickly return it to the "0" position. 2. Repeat this process 4 times, then quickly remove the key. 3. Press any button, such as the unlock button, for 4~5 seconds until you hear a "click" sound inside the car, indicating the key coding is complete. Here is additional information: 1. Smart keys can emit infrared signals to open one or two doors, the trunk, and the fuel filler cap, and can also operate the car's windows and sunroof. 2. Typically, when the owner approaches the vehicle within about one meter, the door locks will automatically open and disable the anti-theft system. When leaving the vehicle, the door locks will automatically lock and activate the anti-theft system. When the owner enters the car, the in-car detection system immediately recognizes the smart card, and the vehicle can be started by simply pressing the start button (or turning the knob) without needing to take out the key. 3. The car smart keyless entry system, abbreviated as PKE, uses the world's most advanced RFID wireless radio frequency technology and the most advanced vehicle identity coding recognition system.
