Needing iron security door lock assistance.

I have a bad iron security door lock assembly that I do not know how to remove. Can someone give me some guidance on removing it? I do not have the key. I have tried to upload pic's, but keep getting msg., upload failed.

Thank you,

Take a flashlight and look into the 2 half-moon holes just above the deadbolt...you should see 2 set screws, that by loosening (CCW) a few turns will allow you to unscrew (CCW) the 2 key cylinders. Might need to use a flat blade screwdriver in the keyholes to get them started. I assume the remaining knob will just pull off.

Thank you!

I'll try that today. The outer door knob had a flange at it's base, that seemed to hold it into the mechanism. Part of that flange broke off and that apparently is what caused the failure. The mechanism still opens and closes the latch, but the outside knob will come off when trying to open the door (pulling) on it.

I'll post the results later today. Thanks again rstripe!

A mortise lock's brand name is usually stamped on the edge plate (removed in your photos) unless it's a Chinese clone or OEM to the door manufacturer.

Metal storm doors/security doors will have one of two general types of mortise locks depending on their thickness; 1-1/4" doors will have the European type lock with the key cylinder usually below the knob or lever. Doors 1-3/8" or greater thickness will more likely have a standard dimension American style mortise lock, with the key cylinder above the knob or lever. You appear to have this style.

The American style has 2 sizes, one residential, the other commercial.
Faceplate (edge plate) dimension: residential=1" X 8". Commercial=1-1/8" X 8".

Backset (edge of door to cylinder & knob centerline): Residential=2-3/8"
Commercial= 2-3/4".

Vertical placement of knob & cylinder are all similar but not exactly the same, and vary by brand. The hole pattern in your door looks very similar to the Corbin-Russwin brand considering the 12:00/6:00 placement of the thru-bolts.

Aside from all the above, your photo appears to show a broken spindle tie-screw, a very common failure in this type. This is repairable, if the rest of the lock seems to be in good order. Can you shoot us a photo of where it broke?

Nope..... Each knob's spindle has a coil spring to maintain contact with the lock's hub, so no spindle screw is used. Each knob is held in place to it's escutcheon plate, possibly with a large circlip. Replacement circlips are available from online hardware sources, but I can't really tell from the photo for sure. However, your latest photo shows this is NOT a Corbin-Russwin, but rather looks like a Marks. They use blue lock bodies and OEM for several ornamental iron doors companies.

I believe they are found at MarksUSA.com. Shoot them your photos.

That lock has been discontinued for many years. if you want to find replacement locks for virtually any kind of door (if products are still available look at Welcome - All About Doors and Windows, Parts and Hardware

I'm pretty sure that's a Marks 22 series lock, and no, they haven't been discontinued. (I called the factory to verify). If it IS a different brand, it's still an exact clone of the Marks 22, and you can get your local smithy to order you one,
or get one from the "All About Doors..." website to which Global gave the link.

The only difference might be the shape of the escutcheon plates, but the mounting holes will still match.
