Thank you D.J. Tighe and all the expert advice I received from forum members!!!!! I put in the refurbished RCM and now my coupe has no codes

Now that I know it was my RCM I am going to order a new one for a spare. Would the best place to purchase from be, Needswings? When I receive it do I need to send to D.J or is it good straight from box?
Again THANK YOU very much, now I don't have to sell and can enjoy driving my car!!
