An addressable embedded transceiver lock (ETL) is proposed. The ETL is equipped with a network access interface (wired or wireless), subscriber serial data interface (wired or wireless), man machine interface and a command decoder. The network access interface is used to communicate with the remote service gateway the subscriber serial data interface is used to communicate with the subscriber home loop and a command decoder is used to take actions as constructed by the remote gateway. When ETL is powered, it first registers with the remote service gateway (a call center or owner of the unit) over a wide area network (wired or wireless). The service gateway maintains profile of the installed ETL and it's communicating capabilities. Upon demand by the remote attendant, the ETL performs operations such as lock open, lock close, lock status. ETL may also alert the service gateway of activities as predefined. Various derivatives of ETL may include Motion Sensor, Camera. GPS capture, Bluetooth and others with corresponding decoding stacks. One application of such device is in REAL-ESTATE use, where a remote broker office attendant may send commands to the ETL to open/close for a potential buyer standing outside a for sale property.
