2 Answers
Methods for programming a car key: 1. Press and hold a button on the new remote control, the indicator light will flash; 2. After the indicator light flashes, press and hold the corresponding button on the original car remote control, then slowly move it close to the new remote control; 3. Release the buttons on both remotes to complete the process. The four positions of a car key are: 1. LOCK position: This is the position where the key is inserted and removed; 2. ACC position: This is the accessory power-on position, turning the key to this position will activate the accessory circuits; 3. ON position: This is the power-on position, turning the key to this position will activate all vehicle circuits, the system will perform necessary preparations and self-checks for starting the engine, and the key remains in this position during normal driving; 4. START position: This is the engine start position, turning the key to this position will activate the starter circuit, which will turn the engine over and start it.
Last time I went to the 4S dealership to get a new key, the technician used professional equipment. They connected the car to a computer in diagnostic mode, and followed the prompts to pair the new key. The procedures vary significantly between different car brands—German cars usually require entering a security code, while Japanese cars might need to cycle the ignition switch five times with a spare key. The most troublesome are French cars, where you have to press the brake pedal and hit the audio button during pairing. Actually, you can do it yourself—for my Honda, just insert the new key into the ignition, quickly turn it on and off six times until the hazard lights flash, then press the lock button. I recommend checking your car’s manual first to avoid locking out the anti-theft system. If you really can’t figure it out, spending a few hundred bucks at a repair shop is the easiest solution.
