Well who on here knows BMW in and out, i am looking at a 740i, and have few questions. Owner is stating car won't start because of a security system being triggered and disabling fuel pump, and ignition. Do i need to just reset the key fob or reset the system itself in the car?

I know some cars u can turn the key in ignition few times and that resets the alarm. Shine some light, and what other issues i should be looking at in these cars.
