@escowen23 You mentioned a 2003 Volkswagen Jetta. I wouldn’t recommend you doing what @Regi54 said. This method, and in fact most methods of hot-wiring a car, will only work on cars older than the mid-90s. Newer models are equipped with a whole host of locking mechanisms in place to keep you from hot-wiring the car unless you’re intimately familiar with the quirks of the model. If you try this even on a 2002 Honda Civic, you’re likely to end up setting off alarms and locking the starter, meaning no one can drive it.
And also, serious damage to the shifting mechanism and steering column can result from this method(unless steering column and gear selector can be overridden - check that in owner’s manual). I’m not saying that this is impossible to do, but keep in mind that 2000 cars and newer were designed to prevent that kind of actions.
And even if you manage to start up your car, the steering column is probably locked at this point, meaning that you’ll have to break it to be able to steer, unless you want to drive straight off a cliff or something.
And to answer your question: As far as I know remote start will only work on cars, with start-stop feature.
