program keys and remote

Does anyone know how to progam keys and remote. I have 1 working key and 2 blanks which I had cut and all they do is unlock the door. Instructions that came with blanks said
 
1.insert programmed key and start car.
 
2. remove key and insert key to be programmed and turn to on position within 10 seconds.
 
3. security light will come on and will turn off when done.
 
But when I insert the new key and set it to on the display reads " service theft system "
 
I've tried with or without clearing the display but the key still wont work. I did this for about 10 min either way.
 
 
 
I also have 1 working remote and would like to program the other.
 
Any suggestions.
