Locksmithing/Tacobi Cosmo safe TB 3E


My battery is dead and I have the dial. We bought the safe 20 years ago before moving to Germany.  Is there anyway for us to open. Or is there anywhere I can find the records to these Cosmo safes. This happened before and we wrote the combo down but, with all our moving, lost the paper the code was written down. Military. We always moved.  Cathy

Hi Cathy,

First let me thank you for your families Military service - as a retired Army officer I can understand the hardships of moving regularly.    Maryland is a beautiful state and Annapolis was always one of my favorite places to visit when I was on the east coast.

The Tocabi Cosmo TB 3E safes were imported (Japanese made) and distributed in the US by a company called Cosmo Electronics in Los Angeles.   Their phone number was 213-858-0433, however I don't believe that they have been in business for about 15-20 years.   To my knowledge there are no records available for combinations for these safes.

while there are a couple of ways to open the safe without the digital code, you will need to have it done by a competent, trained safe technician, at a local safe company.

If you don't have a local safe company, then I would recommend the following company, the owner is very competent, and should be able to get your safe open without damaging it, so that it is still useable.
