Are you still on original engine ecu and uch? If yes, the oem immob is not easy to bypass so not worth the hassle.
If on standalone ecu a hidden switch on the power to ecu or fuel pump will probably be sufficient
Ah that makes sense yeah, I will buy it separately as it is not included.Disklok deters most drive away criminals.
The storage case is worth buying to stop it flying all over the car, cant remember if you get it with it.
