yea the box on the keys idea is pretty sweet except it doesn't give you the option to have a motion sensor....not unless you rig it to be in line with another sensor, but that will make warn away signal pretty much useless. I personally perfer the Directed electronics alarm systems, be it viper, sidewider...and using the optional pager add on, no it doesn't have a little graphic on the pager, but it can do multiple zone alerts and actually let you know which part is going off by zone indicaters, including a warn away zone for a motion sensor. Just a thought. model number for the motion sensor from dei : 508d, and 795t for the pager add on.
