Toyota Venza Forum

I am only a few weeks old in the ownership of a white 2011 Venza V6 AWD with 14000kms. I have conflicting views on whether I have an engine immobilizer or not already inside from the Factory? I have the loaded package with Navigation System and backup camera, leather heated seats, double moon roof, etc Is there something we have to "activate" before the Immobilizer is working? I am not a tecky, so I need lots of clear explanation on this one. I thought that the key system already had it in the special fob that I carry and the push button system...
Please can anyone really help me? If I do not, what are the top 3 tracking systems or, aftermarket immobilzers for these popular Venzas?
