Mortise Lock, 3-11/16 in., Steel, 45 Degree Keyway, Round Faceplate, Spring-Loaded

I would estimate 3-4 mm

Just turn that screw you see in this picture. Requires a flat head screw driver. Clockwise tightens and counter clockwise turning loosens locking distance. Happy adjusting from Phil

No such animal. Talked to 2 Locksmiths and there is no way to key lock this.

Hello Henry, and thank you for your recent inquiry regarding this item. Unfortunately, there is not one mortise lock that is standard to all doors, and there is no sure way to determine the correct replacement lock without removing one and matching its dimensions to those listed online. Patio door manufacturers can often use more than one design within a given series or product line used over the years, making it sometimes difficult to provide an exact match when relying on manufacturer name and series alone. I would encourage you to visit Prime-Line’s website to find the correct replacement mortise lock your patio door requires. Rest assured, Prime-Line Products has a variety of mortise locks from which to choose from that are compatible with multiple patio door handle sets, and there is sure to be a matching lock available for your hardware replacement project. However, to determine which mortise lock is the one you need, it will be necessary to remove the existing mortise lock to match all of its pertinent dimensions. Kindly copy and paste this link into your browser to watch a video that shows how to remove the lock and match its dimensions: http://youtu.be/eBPlyXIv7Ko?list=PL4522DA15175E8D58, or look for the video by visiting Prime-Line’s website and searching for this same mortise lock model number.

Once at this level, look under the “Refine Search” column to the left of your screen and click on the specifications that match your door’s dimensions or features for each sub-category. 7. Compare all relevant dimensions as illustrated in the line drawings and make your selection based on these specifications. Once a matching Mortise Lock has been selected for purchasing it can be ordered by clicking on the Home Depot Logo embedded within the Prime-Line Website beneath the item page, or you can special ordered it at your local Home Depot and have it delivered to the same, or directly to your home.

Yes, it should.

No, there are other sizes that will fit and perform better. Some of them are physically bigger than the one I bought and uses.

Thank you for your inquiry regarding this item from Prime-Line Products. We do have 2 locks that are 1-1/2 inches deep (model numbers E-2100 and E-2171), but not much else matches to this E-2014 model. Our best suggestion would be to for you to email a photo of your lock to our Product Specialists, and to provide them with dimensions so they can assist you in finding the best replacement item.

I initially repaired the Mortise lock with WD 40. I worked perfectly. But only for about a week. Not having more time to fuss with it, I bought a new one.

I am not sure. I did not look for them specifically. I would have looked in the same arear of Home Depot for them. And would expect to find some of them there. Again, be sure of the size. Take measurements or the model # of the door. I took a picture and it really helped me.
