I bought a 2-way viper 3000 car alarm/keyless entry system a few months back and never installed it. I don't need/want it on my car so I'm willing to let it go for cheap. Being a 2-way, your remote will vibrate/make noise to notify you that your alarm is going off.
Everything is still new and in it's box. $100 shipped.
