I know that the spring on the boot was replaced, by Lexus Swindon, about a year ago, but I'm not aware of the lid ever having been changed. The key does indeed open the driver's door. However, I very rarely open it other than via the fob, and when I tried it just now it set the alarm off. Nothing I pressed on the fob would stop it, but when it eventually stopped I re-inserted the key and it opened and locked the door with no problem.
