You will need to take it to the dealership to have them pull the lock code and call Delphi for the unlock code then they can unlock it for you and have them write down the unlock code for you then you can follow the procedure in the owners manual to make your own unlock code or keep the orginal.
this happened to me. there is a code you have to enter. I bought my blazer used and didn't know the code so i took it to a dealer. they will retrieve the code, unlock it and then YOU write it down in your manual for future use!
You can try to download a PDF version ( GM.com or CHEVROLET.com) and even order cd or paper version if they still offer it (10 years old), but it may or may not contain the info you need to unlock the system.There are two versions of this security system, one can be programed using the radio buttons or a scanner the second is scanner only.Wish I could have been more help.Thank's in advance for rating me !
Can purchased an adapter kit at Best Buy or Circuit City that is color cordinated with the factory wires for about 12.00. This will go right into the factory plug.

I once took off the factory radio from my s10 99 chev blazer... to install an MP3 player... Then I sold the Mp3 player and had to reinstall the factory radio back on my blazer... It asked me for a code... and I didn't know where to find it... So I entered the year of my truck "1999" and it unlocked it. Try entering the Year of the model! It should work.
