Locksmithing/York model 400



I recently purchased a home built in 1940 and found an old wall safe set into the brick basement foundation wall.  It is heavily rusted, but the dial turned freely.

After some research, and after reading your response to earlier questions from others, I determined this is a York model 400 safe with a Yale 2421 lock.  

I have unlocked the safe successfully.  I figured out the combination and after entering all three numbers and turning the dial back right, I can feel the locking bolt slide and the dial stops rotating at about position 85.

I cannot, however, rotate the outer door wheel to retract the lugs and open the door.  I understand this should rotate right (clockwise), but it won't budge.  Not one hair.

Is there any way for me to determine whether the relockers have engaged, preventing me from opening this safe, or if it is the rusted door keeping it from rotating?  Any suggestions you have for curing either possibility would be welcome.

Hi Gordon,

So you have a model in the 400 line, Wheel type, lug door, and you are assuming that it has the yale 2421 lock.

I'll start with the "lug" issue.   The lugs do not "retract"!!!   They are part of the frame and body of the door (two sets).   In order to open the door, the door and lugs have to rotate to a free area, in between the opposing lugs, then the door can be pulled out of the cavity, to open.

If you cannot rotate the door, then either the door is rusted shut or the locking bolt is NOT fully retracted.   As the door will not budge, I would assume that it is rusted shut.   This is a very tight tolerance door, and the slightest amount of rust will jam it up.

Unless the safe has had a burglarious type attack, then the relockers are not fire off.

Course of action.

1.   Visually inspect the locking bolt to ensure that it is fully retracted.   If not then it must be retracted.

2.   If it is, then the door may need to be soaked in penetrating fluid, and "shocked" with a dead blow hammer, to loosen the rust.

Mechanical issues such as this require skilled hands on service by a trained safe technician.   This is not a DIY type job or for a locksmith - you will need a safe tech from a local safe company.

lastly, just as with the need to visually inspect the locking bolt to ensure it is retracted, the relock bolts can be visually inspected to see if they are active or not.   This will require drilling and a fiber optic inspection scope.

Sorry, I can't be of more help, but this IS going to be a hands on project.
