Ok so the trouble I'm having is anti lock system comes on and I don't know what to do I tried chaging module can I make a key fob instead of having just a fob

 

Well first you have to taste colors to smell sounds.

 

I don't understand if you're mixing terms or if you are asking about two separate topics, which I think is also what Magnoom is getting at. The Anti-lock system is not directly related to the key fob. Maybe there is punctuation missing to separate your thoughts.

So assuming the ABS light comes on, have you used a scan tool capable of accessing the ABS system to see what diagnostic code or codes are present? When changing the module did you re-code it to your car?

And assuming you're asking about programming a second key fob so that you have more than just one fob, I'm not real familiar with the 2008, but I suspect it requires a high end scan tool (which could also read ABS codes) and it may also require knowing the PIN code for your car. If a PIN is required, some scan tools are able to read the PIN code (such as AlfaOBD if you have an Android phone) or you can get it through your dealership, who may or may not charge you for the PIN.
