I feel so inept! I'm a 67-year-old disabled woman living alone (ie: no "man" available that may know about such things, lol) and on a shoestring fixed income. I was homebound for about 8 days with bronchitis about a month ago, hadn't driven my car. When I felt well enough, tried to start it & it was completely dead. Got a battery delivered from Auto Zone and proceeded to change the battery myself. Now I'm reading about having to reset things, which I never did. Some of the "issues" that might result sound very familiar. Should I do something else now?
