         | Maybe the answer is to give the user the option to arm the
         | alarm or not when exiting, with equal friction (i.e. separate
         | "lock" and "lock+arm" buttons on both the door and the fob).

         | That really depends if you're close enough to the car, or in a

         | Car alarm systems should be silent and sent an alert to your

         | vehicle and can check on it in a timely fashion.
