anti theft system activate not start and rear lights stay on

You won't need reverse lights if you can't get it running so tackle one problem at a time. How do you know you have a security problem?
Do you have a security indicator on or flashing?
Have you tried a different key?

Hello Thanks To Take The Time And Help Me With this problem With my car. Yes anti theft light is blinking fast.
and also I have tried different key too, and still the won't start problem.

You have pretty much reached the limit of what you can do yourself. From this point you are going to need a factory level scan tool for diagnosis and likely will have to do some programming when the problem is repaired.
