Antique Safes/Migh-T-Safe


We have a Migh-t-safe floor safe, serial 5257, in a 1930's house, and we have the combination.  It has been many years since we opened it, and now it doesn't want to open.  I feel the "click" at the last number, but when I then turn the dial left, it stops, but safe won't open.  Feels like it wants to, but perhaps there is dirt on the bolts, or?  Dare I squirt WD-40 or something around the edge of the cover?


I doubt that you have ever had it actually cleaned and serviced.   Mechanical items need regular maintenance to keep them operating.  Due to the unique mechanical arrangement in this particular door, and its "friction" actuator, dirt & debris or old lubricant can cause it to cease operation.

WD-40 is a water displacement and/or penetrating type fluid and NOT a lubricant.   It should never be used in locks.  Even if you tried to flush the door, the majority of the fluid would only make its way into the bottom of your safe, ruining any documents you might have.   Very little would find its way into the lock.

As far as it being in a 1930's house, this company appears to have been in business from the mid 1950's until around 1970.   I haven't found any references earlier than 1955 or later than 1970, so it only appears to have been around for about 15 or so years.  So your safe could be between 40-60 years old.

You can try "rapping" on the safe door at the point where you feel it trying to "click" (engage), to see if it will unlock and retract the locking bolts.   Use a deadblow hammer or rubber mallet - you are hitting it for effect - if you are causing damage then you are hitting it too hard.

If you still can't get it open, you may need to have a safe technician from a local safe company check it out.
