I had the same problem and the company was not responsive. I did finally find the solution to a missing lorex password. It's simple.. just take out the screws holding in the back (the little screws, not the larger ones holding on the monitor section). Inside you will have to unscrew the screws that hold a couple of the smaller attached circuit boards to get to the battery. Just remove the battery and wait for a couple minutes. Re-insert the battery, put the thing back together and VOILA!!! That's it.
