So I lost one of my remotes for my original alarm that I installed back in the day when I bought the car new. Instead of trying to find an impossible remote replacement, I'm just going to install a new alarm with the latest technology. I park it on the street so I want to upgrade to a 2-way alarm, something like the Viper 3203.

I'm assuming this isn't just a matter of replacing the brain of the unit, so does anyone have a good DIY article with photos?
