I did a search on the forums... but
came up with nothing (except the fact people
don't really like this feature). Has anyone
done this mod, along with the shock sensors?

I'm looking to auto lock the doors after
say... thirty seconds with the factory
alarm in place.

I'm aware the Viper 550 ESP does this and
more.

 

And how many time do you think you'll lock your keys in the car. A friend of mine had that same setup put in. The first time he washed his car, guess what.

Well after the system locked him out several times he yanked it back out.

Fun to have, but watch where you leave your keys when you get out of the car.
