headlamps

ok, i have just ordered new HID bulbs, but on the driver side, the rod that you turn to unlock the headlight housing has dry rotted n broken (the rod that you have a tool for in the trunk area), is there another way to get the housing open or do i have to go to the dealer.............and for those who are following my posts, the last problem i had has been diagnosed to be the main fuel pump needed to be replaced $500.00 job.
