How to Pair a Remote Control for BYD F3?
2 Answers
You can go to a 4S store and ask the maintenance personnel to help pair the remote control. Here is some information about car keys: 1. When the car key is turned in the ignition switch, the engine control unit (ECU) in the car will send a set of encrypted electronic code signals to the chip inside the car key. The vehicle will only start if the car ECU unit can read and receive the correct anti-theft code signal. 2. Therefore, even a simple car key without any buttons can activate and deactivate the vehicle's anti-theft system through the internal chip encoding.
I've tried several methods to pair a remote with my BYD F3. The most traditional way is using the original car key: First, sit in the car and close the door. Without pressing the brake pedal, press the start button twice consecutively. At this point, the dashboard will display 'ready to learn.' Then, simultaneously hold down the lock and unlock buttons on the new remote for about ten seconds. Release the buttons when you see the hazard lights flash. This method usually works, but some model years require matching the engine immobilizer chip, which requires professional equipment. I recommend checking your car's specific year and model first. Some older models don't even require pressing the brake pedal—just insert the key and turn it to the third position to pair. If you still can't get it to work, you can buy an OBD matching tool online for just a few dozen yuan, or spend about a hundred yuan at an auto parts market to get it done.
