Programming method for the key: 1. Enter the car and close all doors, then lock the car using the central locking button on the driver's side; 2. Insert and remove the key 6 times, and the central locking will automatically unlock; 3. After unlocking, use the lock button to lock the car again, then insert the key and turn it to ACC position, and press any button on the remote; 4. Once more, use the lock button to lock the car, and press the lock button on the remote to activate the central locking; 5. Remove the key, open and close the door, and test the remote. Reasons why the car key does not respond when pressed despite having power: 1. Severe signal interference in the surrounding environment; 2. Damage to the key's control unit; 3. Key code mismatch; 4. Dirt inside the key causing poor contact; 5. The key is too far from the car; 6. Vehicle malfunction, such as damage to the circuit board relay or issues with the car's central locking system.
Last time I lost my car remote key and was running around in a panic. I immediately drove to the 4S store for help. They said they needed the vehicle registration certificate and ID card to verify my identity and prove that I was the owner. Then they used professional equipment to connect to the car's OBD interface to program a new key. It took a little over an hour in total and cost 500 yuan. Although the cost was not low, it was safe and reliable. From now on, I will keep a mechanical key at home just in case. Nowadays, many new cars have more complicated key configurations involving smart chips, so don't try to DIY it blindly.
