Here is a Trustee electronic safe opened today, lost code and no power. Using a special tool I managed to get the safe open without damage which is fairly rare in the case in electronic locks as when they do fail or the code is lost in many cases the lock would have to be opened using destructive methods. Very happy this opened the way it did as I had no information about the internals of this safe. Happy to say I do now!
Shortly after opening this safe I popped out to open another home safe. This took longer than expected but finally opened non destructively and showed the customer how to reset the code. No photos of this one sadly, but another open safe!
