The wife and I bought a home a few months ago and want to now start using the alarm system while we're away durning the days. Only problem is that this house was a foreclosure so we can simply just asked the previous owners what it was so we can change it. I tried calling the company that is listed on the main junction box in my master bedroom closet and the phone number is disconnected. Can just any alarm system company come out and reset the code for me? I'm not interested in hooking it up to the phone system though, since I don't have a home phone.
