Very easy. Take it to the dealer and they will do it in about 15-20 minutes.
After all, it is a Lexus. Like most luxury vehicles; Range Rover, Cadillac, Infinity, or Hummer, If you can't afford the maintenance, don't buy the vehicle. I hate it when I see a newer luxury vehicle that has a broken/blown light or body blemish. Yeah, you look really cool driving a expensive hooptie.
Good luck.How hard is it to change car battery on lexus 300?it's not that hard remove the terminals and then the bracket that holds the battery down
