Wouldn't it be simpler to steal another car ?>:-}

Not really. For the acronym challenged:

FOB = Key fob. The thing that dangles from the key chain that unlocks the door and makes the car run.

ECU = Electronic Control Unit. The main black box that controls all the other black boxes.

ELM = ELM327. A microprocessor by ELM Electronics that is used to convert OBD2 (On Board Dignostics) data into something intelligible by humans.

CAN = Controller Area Network bus. Used by black boxes and gizmos in the car to talk to each.

ACC = Accessory mode. That's a key position where you can play with the radio and LCD console buttons without running the engine.

VAG = Volkswagen/Audi K-Line = ISO Protocol ISO9141 on a one wire bus.

Pretty sure e.g. OnStar will start the engine for you in an emergency even if you don't have active service as a courtesy, if you call from a phone # that's on an account associated with your VIN.

NissanConnect or whatever might do the same if the 2011 is new enough to have it

Or a reposessor
