hi i got a 98 prelude and i left my lights on and the battery died so wen i jumped it the stereo said code. so i took out the stereo got the serial and called honmda and got a code. then i just unplugged the stereo and and plugged it back in to reset it and entered in the code. But the code dont work. i called several different dealers and they all give me the same code. maybe do i have to disconnect the battery to reset it? also in the ashtray there is a 8 digit number and another 5 digit number so i tried the 5 digit but that code didnt work. since the code they gave me dont work theres nothin i can do?
