I've got an '05 sedan with the Intelligent Key (which I love). I'm thinking about getting aftermarket rims, which has me thinking about upgrading the factory alarm.

Does anyone know if it's possible to maintain functionality of the Intelligent Key while adding aftermarket alarm features such as a back-up battery, tilt sensor, shock sensor, glass breakage sensor, etc.? It seems like it should be possible, but wanted to hear from people who may have done it.

I've done tons of searching but couldn't find anyone who's posted about it yet.

Thanks!
Thomas
