Hi,
If you are still having problems operating your safe then the following may help.
You must have the gold key (master), a silver key (user/guest) and last safe code (default is 123456)
The gold key is your master key for the safe so DO NOT Lose and DO NOT Give to anyone else, ie your guests or the bloke down the pub. It will help unlock the safe without the safe code.
The silver key is the key to give the guests staying in your apartment. The key is can only be used with the safe code.
So,
1. Enter the silver key into the safe but do not turn yet.
2. Enter the last safe code using the safe's pinpad. The default safe code is 123456.
3. A green light on the safe's pinpad will light if the code is correct. When this happens turn the key.
4. The safe door will unlock and can be opened, To lock the safe, close the safe door and turn the key.
The safe code can be changed so not to use the default code which everyone knows. I can not remember off my head as I am at work at the moment but will add this information later on today with a link to the manual in English.
Regards
Ade
