It doesn't on my 2004. The kids have come back inside more than once because they took more than x-seconds to get to the car after I unlocked it from the entry-way of the house. Timer seems to be the same with one or both doors unlocked by the fob.

 

Nice pranks (if their cars work like mine). Doing that will make my alarm go off. I can open my trunk with the key or fob when the doors are locked, but the alarm goes off in about 5 seconds.

Fortunately, our alarms can be cancelled by the fob. Geez, remember the older style on some cars which required the key in the ignition to cancel the alarm? Hard to be or look smooth tripping and fumbling for the ignition while the car shrieks a debilitating siren at you.

 

Yes I do. Is that the difference? I thought the shock sensor upgrade only had to do with motion of the body.

My alarm also goes off if someone pulls on the door-handles. There were two occassions where my alarm seemed to go off for no reason. At first I though perhaps something in my pocket had hit the panic button, but I wasn't really close enough for that to work in either case. One was almost certainly a coworker trying to get a better look or make some mischief, but no one confessed. The 2nd incident was when the car was parked on the street in Watkins Glen - again, either a better look or some mischief. I didn't see anyone from the 2nd story window so I cleared the alarm with the fob and shrugged it off. Then, recently, I set off the alarm by trying to open the drivers door when I'd forgotten it was locked. Imagine my surprise.

I've burned myself with the trunk a couple of times. It's too easy for me to forget to unlock the doors when I first or only want something in or out of the trunk. Should be easy to remember - the salesman who sold me the car popped the trunk first thing so we could look in it before our test drive and set off the alarm. Still cracks me up to think of it.

EDIT: I didn't seriously think you'd maliciously prank them on purpose, but boy did I get a good laugh at imagining their faces the first time they tried it!

 

Yeah, experiment with it where you have a little privacy. Not a cool thing to discover 'must not do x' in front of a bunch of friends or pulling up to a party.
