Try waking the device up with however the documents recommend (tiny button, open close door, etc). Then quickly try Get in HG. Some ZWave devices (typically battery powered sensors) are usually sleeping and only wake briefly to transmit data. If it is a line powered device, they usually stay awake and should respond more reliably.
Since you had two devices of same type, try adding the other to dashboard and see if it is working.
Unfortunately I don't think you are going to get what you are after :-( A new widget (at minimum) needs to be created for this type pf device. I don't have any door locks or garage door sensors so I don't know for sure if anyone else here has gotten them to work.
Do you have any other ZWave devices to test with? I recommend starting with an always powered switch/dimmer of some sort; this will confirm that ZWave is working.
