A monitoring device in accordance with the disclosure stores a serial number list in non-volatile memory, the serial number list including data indicative of at least one valid serial number associated with one or more key fobs permitted to interact with the monitoring device. The monitoring device is configured to receive a wakeup signal via a key fob interface configured to communicate with a key fob. The monitoring device reads a serial number from a key fob via the key fob interface and searches the stored serial number list for data indicative of a valid serial number matching the serial number read via the key fob interface. The monitoring device reads action data from the key fob via the key fob interface, the action data being indicative of an action to be taken by the monitoring device. The monitoring device, in response to the read serial number matching a valid serial number of the stored serial number list, takes an action based on the action data.
