i have a daewoo lanos sx auto (t reg) 1999 1600cc.when i replace the batter?

To obtain your code... You can try calling Daewoo Motor America (the company still operates a HQ in CA for service/parts/warranty purposes); their website is still www.daewoous.com. You can also try calling your original Daewoo dealer, who hopefully still has some technical materials and personnel to help you identify your unique code. Some General Motors dealers may be able to help, as GM acquired Daewoo and still sells Daewoo-made cars in the US under their Pontiac and Chevy brands. But all methods above may be difficult for an individual detailed problem such as obtaining your unique radio code.
If all else fails, TRY THE CODES BELOW, which were the most common codes used in models during the 1998-2001 model years.

no, fitting your battery is straight forward and shouldn't need to reset anything, you may lose the use of your radio unless u have the code.
