After reading 100's of posts and finally going on a 45 minute drive with constant alternating ".* Key detected in vehicle"**warning alternating with "rear door open" warnings and 45 minutes of constant beeping.* I knew I had to come to a*conclusion.** Either find a fix, or drive the vehicle over a cliff.
* I searched 100's of posts of people spending money, time, and energy at the dealer attempting to* find a fix*with very little luck among any of the posters.
.* I ended up fixing the problem for 48 cents.
.* I was unable to find the original post that recommended this*, so that I could*thank the person* that came up with this idea, but I will pass it on.
*First, I took electronic spray cleaner and thoroughly sprayed the inside of the rear hatch door latch.* There is a small rectangular carpeted cover the can be easily removed with a flathead screw driver to allow you to spray into the latch itself.* This definitely improved, but did not fix the problem.** You can get electronic contact spray cleaner at Walmart or RadioShack.
**You then*need to buy*1/4 inch lock washers.* This cost me 48 cents.
*Open the rear hatch door, and on both sides of the bottom of the door you will see, rubber bumpers sticking out from the door.
*Look down by the rear bumper where those rubber bumpers hit when the door is*closed.
* With a Phillips head screwdriver, remove the*rubber washers down near the rear bumper.
*Place two lock washers under each of the*rubber washers*to help raise them up and screw them back into place.
* I have driven over speed bumps, I have gone over a curb and no alarms have gone off.* Prior to this fix I could not hit a pebble in the street without an alarm going off.*** For a year, *I have been dealing with this problem and it only took 48*cents to fix it

I posted this answer to the problem in December 2016.
I have added an addendum because the problem began to recur

Buy*1/4 inch lock washers.* This cost me 48 cents.
*Open the rear hatch door, and on both sides of the bottom of the door you will see, rubber bumpers sticking out from the door.

*Look down by the rear bumper where those rubber bumpers hit when the door is*closed.

Addendum:
I did have a recurrence of the problem after the above fix, but not as bad. At Home Depot, I obtained #14 1¼" screws. I ended up putting three 1/4" lock washers underneath. It has again cured the problem. With the 1-1/4" screw, I can always add another washer underneath if it recurs again. Total cost, less than $1 to fix the problem.
