There is one part that is in need of caution.  There is a ball bearing in the internal works, part "13", this is the only thing that can give you trouble, but not when you are removing the lockset from the door.  The replacement locks for your particular lock are available from time to time.  If you are not sure of yourself, there are plenty of folks that have taken theirs to a locksmith and had keys and locks replaced for fairly inexpensive pricing, and then all is well again.  Don't panic, it'll get fixed!

Whatever you do, don't over-lube it though. Gun oil is a good idea, but it will drool down the door if you use too much. So will Thrust (penetrating oil) or 3-in-1 oil....wonder how I know this??

Gary,

Mine had a small hex-head set screw in that hole. That was rusted in place. I took the whole thing to the locksmith.

I work on and sell these locks and can tell you if you are going to replace the lock cylinder then drill out the brass pin. With the key broken off in the cylinder driving it down to remove the cylinder might be impossible. If you can get forceps or some pin type object to remove broken key that would be best then a locksmith can make you a new key. Otherwise drill out pin then remove cylinder and order from Vintage Trailer Supply a new lock cylinder. To install new cylinder make sure key is inserted in new cylinder, push the pin down into cylinder, insert into lock, rotate key which will drive the pin upward into hole locking it in place. There is a YouTube video on this.

IF in doubt take it to a locksmith before you make a costly mistake and ruin the lock. Some locks are vary expensive to replace. The last lock I took to my locksmith cost me $12.00 with to new keys.
