My 1998 Accord EX battery was getting real tired on these cold mornings, so I took it to WalMart for a new one. I explained the radio's requirements, and they assured me that they are professionals and would do the job correctly. They used a "reserve power" plug to maintain voltage to the anti-theft radio during the change. It didn't work. No, I don't have the code, because it didn't come with the car when I bought it, used. The honda dealer has me scheduled to remove the center console, and radio, and get the code from Honda. His estimate is . Is there a method, using the power recepticle, that would work? How should one do it? What is the approved method? Al
