For the issue with the driver door not unlocking, there are a few potential causes that you can check. First, make sure that the battery in the key fob is not dead, as this can prevent the door from unlocking. If the battery is fine, then it may be an issue with the lock actuator or a wiring problem. You can try removing the door panel and checking the wiring connections to make sure they are secure, and test the lock actuator to see if it is working properly.
As for upgraded rotors and brake pads, there are many options available depending on your driving needs and preferences. Some popular brands include Brembo, EBC, and StopTech. It's important to make sure that any aftermarket parts you choose are compatible with your specific ILX model and will provide the performance you're looking for. You can consult with a trusted mechanic or do some research online to find the best options for your needs.
