Liberty absolutely maintains the combinations for all mechanical safes... they openly acknowledge it online..
The problem is.. they tell you they do that for customer service.. and that no one other than you, the owner can get the combination.. and that even then you have to prove you are the owner of the safe before you will be given the combination...
If you have registered the safe with them the process is relatively simple, but there is still a multi-step process to go through..
If you have not registered the safe with them, then there is a pretty complicated, muti-step process to go through that will take at least a couple of days to complete (you have to have documents notarized stating you are the owner, provide identification, provide proof of address, provide proof of actual ownership (reciepts, etc)....
BECAUSE they claim they wont give the combination to anyone, other than the owner... because they dont want anyone getting into the safe except the owner..
Clearly thats a lie.. because they helped the FBI get into a customers safe in a in no time... It was actually easier and faster for the FBI to get into the safe than it would be for an owner to get into their own safe if they lost the combo..
What they also do/did was build in a "back door" according to the news reports that they dont bother to disclose to their customers.. which is what they gave the FBI (if I am understanding the reports correctly, they didnt give the FBI the actual assigned combination.. they gave them the back door code to get into the electronic lock).
