97 explorer radio

help needed please i recently disconnected my battery to reset the codes on my explorer worked fine but now the radio is asking me for its own code....i dont have it and i dont have the documentation that came with the truck either, i think it may still be programmed with the factory code ..can anyone tell me what the factory codes are and ill try that ..if not i will have to take it down to the local shop and get it decoded hope someone can help ...

thanks

that sucks. I havent had that problem so far but now ill be careful. I did have the same problem on my 2000 honda civic. I took it down to the dealer and they gave me the code. they charged me about 80 bucks just for the code
