I am sorry I do not have any tips on removal of the old door latch. I have personally never worked with lavatory partition hardware. Be careful you do not hurt the frame during the removal of the old door latch. I will try to find out more information on how to remove the old door latch from other contractors I work with. Let me know if you come across a solution yourself.

I've placed you in an existing discussion regarding the installation and removal and installation of 10-554 Concealed Door Latch.

As for the installation, please take a look at the diagram above.

Unfortunately we currently do not have many tips on removing the old door latch.

Just removed one. Since you are replacing it, breaking it shouldn't be an issue. You will need a hammer, vise grips, and a slot screwdriver.

Take your visegrips and twist off the inside knob. This will allow you to push the latch all the way out, giving you access to the inside of the unit. With the latch out, put your screwdriver into the outside indicator opening, with the handle out towards the extended latch, pry the outer plate, so that the side closest to the hinge, is off the door surface about an 1/16". Now, from the inside, use your screwdriver and hammer to punch, using the indicator opening again as your punch point, hit it and it should come out. Mine did, but your results may vary.

Yes! Just removed two and replaced two. It's really a two person job, but I followed the Quick Learner from Keene, TX's advise and it worked!

Drill a hole just above the "Occupied/Unoccupied" indicator window (outside of the door). That will remove one of the tabs that locks it in, and it should pop right out.
