Hi, my company has a Diplomat 100safe. Years after years, there were changes for finance manager.
Now i m the newly recruited finance manager. I was not told that no body has the combination to the safe.
My itch hand when n spin the knob.  Guess what, they cannot open the safe just with the key only.
No body knows the combination number to the safe.

I sincerely need you help to guide me to open this safe again.
Please help me.
Thank you.

As I am not the manufacturer, and have no access to their records, I'm not going to be able to provide you with a combination.
Diplomat Safe Company was established in 1982, in Busan, Korea.  Their contact info is:

If you cannot contact them, or get a response to your inquiry's, I would recommend that you call the following company to have your safe opened and the combination recovered:
