I vacuumed my car yesterday with a car vac that I have used for years. When I was cleaning the interior afterword I noticed that my power door locks were not functioning the way they normally do. I didn't think anything of it. Today I tried to start my car and it wouldn't even turn. The door locks are still slow and when I honked the horn it sounded like it was dying. I am assuming that the battery may just need a jump or even replaced. I have a Honda Civic 2005 LX with 40,000 miles on it. Any suggestions on what this my be?

Don't jump modern-day cars--there's too much risk of damaging the ECM, alternator, and sensors. Instead, remove the battery and place it on a charger. This is what you might try. Since Hondas come with only a 36-month battery, however, you probably should buy a new one. I doubt anything else is wrong.
