Hello, when i purchased the BCD436HP Scanner i purchased an upgrade key as well which came pre installed on the scanner and i was never sent an email giving me the key. My scanner is dead and im sending it into Uniden for repair and I've read that Uniden will sometimes wipe the scanner clean which also wipes the upgrade key. Is the upgrade key stored somewhere on the SD card? If it is can i find that key by loading the card onto my computer? What would i be looking for on the SD card if that were possible? I appreciate any input.
