As long as your aftermarket alarm system can trigger the door lock/unlock outputs then you can use the remote portion and just wire it to your doors. Otherwise these window devices will work fine on any window you install them onto.

Update:

We are doing a little circuit modification right now and figure in a week or two we'll have the updates. I'll test them again and try to get us back on track.
