Sentri-Lock offers wireless alarming, electronic key renewal, with digital technology. Access to your home is controlled and monitored better than ever. No missed opportunities for potential buyers and agents to access your home due to deficiencies of the old "tumbler’ style lock boxes that include lost or misplaced codes that can compromise the security of your home. With this new technology, only licensed realtors that are members of the local Board of Realtors have access to an electronic card that is registered to them for the use of these lock boxes, and we carefully track this use. We know who is entering your home, and now you do as well!
