Hornet makes one, its an alarm thats meant to be added to factory keyless entry. I had one way back in the day. You can add various sensors to them, but wiring it up yourself would be a nightmare. But essentially it did what you're looking for. It armed with the lock button on the keyfob and disarmed when you unlocked via the keyfob. I'm sure the buttons on the door are more than likely on the same page but don't quote me 100% on that.
Like I said it wasn't a super great alarm, but it would go off it someone bumped the car, or opened the door/trunk and stuff.
Hah! found it on their website! http://www.hornetcarsecurity.c...D=805
I'm sure other companies make them too, but I guess really and truly as they put it, its an upgrade alarm for your oem keyless entry.
