1996 Roadmaster Wagon- Does This Radio have a special security code??

I have a 1996 Roadmaster Wagon with a stock radio.
I purchased a 1996 Roadmaster Wagon stock Radio from a junkyard.
Will this plug in and work or is there a Security code I need the dealer to input
to get it to work.

I know some of my 2002 + cars had code and anytime
the battery dies I had to input the code the car came with.

Thanks for any help.

There is a code the original owner was supposed to input. Do a google on "Unlocking Delco Radios".
