Car Alarms: 2009 Camry Keyless - Extended Range, kansas city area, horn sound

Question
Hello, I just bought a 2009 Camry.  Since I am always losing my car in big parking lots, I want to extend the range of the alarm button.  What are some options to make the horn sound off from 2000 feet away?
Maybe I need to attach an extra wire to the receiver and place it higher in the car for a better antenna.  Or maybe I need to get another receiver and rig it to the horn.  Could my Toyota Original Equipment Fob be rigged to a stronger receiver?  
I am from the Kansas City Area.  
Thanks!


Answer
The only option there is replacing it with
a system that has 2 way operation.

Have a look at www.pagingalarm.com or www.caralarmstore.com
for some ideas on what is possible here.

You can not extend the range of most systems
like the 09 Camry has.

Let me know if something interests you on those
