Remove US lock double deadbolt

Hi,
I have US Lock deadbolt lock in a metal door, (key with the same key on both sides). I have read many posts, but am still unable to remove this lock. The bolt will no longer extend and am trying to replace the whole lockset, but cannot find anywhere to get it to come apart. I tried allen wrenches around the bolt and nothing. It doesn't appear there is any allen screw or anything to depress.
Any help or suggestions would be appreciated

Hello whatifjohn, and welcome to the board. I have to ask you, is there two little round spots on the inside of the lock face? If so, insert the key, and turn it to about 1 O'Clock. This should expose the two screws holding the inside lock in place. This is the type I think you have, and the inside screws are hidden by an inner plate which rotates as you turn the key.

If not, you will have to remove the faceplate of the bolt. Look on either side. You should see an opening. Use an allen wrench about 3" long, and I think about 3/32" is the size. It's pretty small. stick it into the opening next to the bolt. You may have to fish around, but you should find a set screw way inside. Loosen the screw until the lock cylinder is free to turn. I recommend you not try and remove the set screw, as it could fall inside, and be gone forever. Once the lock cylinders are out, you can remove the bolt itself by removing the screws that hold the inner ring. They go through the bolt, so it has to be taken apart in the door.

Hope this gives you a starting place. Let us know how it works out.

Question Remove US lock double deadbolt

Thanks for the quick response Cuedude.
No, there are no screws hidden by an inner plate. The tumbler is the only thing that turns with the key.
There are 2 holes on the bolt end, no end plate, but I have fished around for hours with 3/32 nd allen wrench and others and cannot find a set screw or any other thing that would resemble a screw in there. Is there any other possibility?
I have photos I could send via e-mail, I do not have a place I could post them to send with a link yet.

Hi whatifjohn
If there is a hole on each side of your bolt, then there are indeed allan screws in there. Is your allan wrench bottoming out in the holes? The wrench needed is about 3 or 4" long. Sometimes it just takes a lot of patience to find them. Once you do, just turn them out about 4 turns.

If the wrenches you have are'nt doing the trick, then perhaps your local locksmith shop can provide you one. We often just give them to customers as a courtesy, but even if you paid for one, it would'nt cost much.

Regards

I do not have a 3/32 over 3" long, so I guess its possible. I can however hit the housing inside on a horizontal plane at about 2 ". The distance from the center of the lock to the door edge is only 2 3/8 in, so are you saying that it could be past the center or off the horizontal?

I really appreciate the help

Good Morning,

Actually, the way the latch is constructed, there is a constriction about an inch in from the edge of the door. But there is a hole big enough for the allen wrench to fit through. We'll get through this, honest.

Should there also be a set screw on the outside hole of the bolt? I have bottom out at about 2" and have tried different size wrenches, on both sides of the bolt.

When your right your right. I finally found the set screws with the right size wrench. It was not part of any set I had, but I found one odd size wrench and it hit them right on.
Now the problem is, I have turned them about 6-8 turns, having to use a pair of pliers on the end of the wrench and can't get anything to budge. Any more force and the wrench will twist. I have done this on both screws, but nothing.

Wow, what a major hassle..but I feel that I am a little closer to getting it off.

Do you know any other things to try to get it come apart?

Whoopie...its off.

WD 40 on the set screws via a nozzle straw and I got another 6-8 turns out of it. 26 year old lock was a little corroded I guess. Then I realized that the lock itself had to unscrew, this was easily done by turning the whole lock with the key.

I can't thank you enough for steering me in the right direction.
The time it took was way to much for what should have been a simple job, I probably should have just got a Locksmith. But you know the type, once I got into it, I couldn't stop, it was a challenge.

I am going to try and post some photos of the set screw issue, since I see that this issue has come up many times before on different boards. That is if I can really get a real closeup. If I do I'll leave a link here.

I have updated the photos to show the set screw, since even if this helps one other person, it will have been worth it.

I agree, great pics of the latch bolt and the screws. It's really hard to describe verbally. Especially when I take it for granted, as I do these almost everyday.

The lock you have carries the US Lock name, but it's made by Lori. It is a very sturdy lock.

Thanks for the update, and it was a pleasure to help out.
