I have a residential system monitored by a big national company. I just had my worn-out wireless keyfob replaced and the tech took the old one with him (I should have said it was lost). I noticed on the paperwork he assigned all new zones for my new keyfob, and apparently
*didn't* disable the zones assigned to the old one. So now I have to assume he left with a largely functioning keyfob to my system. On the off chance that he's crooked, any suggestions on how to secure my system against that keyfob?Thanks.
