Does anyone know if the alarm/remote unlock will still operate if power from battery to starter (or similar "immobilizing" setup) is removed?

I kinda liked the following item, but if it would not allow my unlock/factory alarm to work, if it is serving the same purpose as the factory alarm, or if it is just plain "overkill" ------ let me know. :cool:

Choose "Kill Switch with removable key" on the top bar

If you lose power to the starter, it could disable the entire car. The factory alarm already has a starter disable function on it.

Looks like a pretty cool little system. Wish I had one on my car :(. Maybe I'll get one, so I can turn off my stock parts in a cool way! :D
