You can plug into the cigarette lighter socket. They are usually hot all the time.

Sorry, guys, but nope, won't work. The lighter is not powered until the ignition is turned on. Bosch has been doing that for YEARS. Turning on the ignition switch may or may not make the contact since there is no power to the system until some gets introduced, somewhere. Check the owner's manual. It will have, somewhere, a procedure for opening the hood in the case of total electrical failure.
