If trying to start while being jumped off, be sure to hold down the hood switch.

As for the alarm being advanced, note how easy the horns can be reached on this D1.

For the level of problem immobilzation causes, I wonder if it is worth it. We don't have many posts about how glad I was that my 190,000 mile D2 with sixteen oil leaks and one nasty engine tick was saved from thieves who attempted to make off with it by robust immobilzation. If I were a road warrior owner of one of these, with SWMBO driving it while I was safe on the 12th floor of the Marriott 3 time zones away, I would sure have towing coverage.
