So I had to replace my anti theft deterrent moduel. And now it won't crank. Headlight come on. No dash lights no nothing.

 

Does the security light on the dash come on

 

yes it stays on.

 

Google: 30 minute key relearn. And follow the instructions…

 

I have tried that and the security light stays on. I have a key fob and I have tried to reprogram it also..

 

You may need to start from the beginning and have the vehicle computer updated as to the changes made. You have 2 choices either a dealership road call or certified locksmith. Certified means access to security info. Get some idea of who charges how much, then make your decision.

 

Yup, gonna need to take it to the steelership…
