Yale door locks install instructions

Yale door locks install slightly different than other manufacturer door locks. When replacing door locks, you will not need to bore the hole through the door but you may need to make the hole in the door jamb deeper. The door jamb is where your strike plate installs and where the deadbolt will effectively lock the door. The Yale lock employs a hidden screw system to hide the installation screws of the door knob.

Insert the latch bolt assembly into the side edge of the door with the curve portion pointing to the outside of the door. Push the latch assembly all the way into the door until the latch plate is flush against the door. Secure the latch plate to the door using the supplied wood screw and your Phillips-head screwdriver.

Measure the thickness of your door with a tape measure. Doors are either 1 3/8-inches thick or 1¾-inches thick. Grab the Yale door knob and pull off the inner knob and set the inner knob aside. You will need to adjust the outer plate to fit the door. The outer plate is called the outer rose. There is a large nut on the shaft of the door lock. You will be adjusting the gap between the back edge of the outer rose to the front edge of the large nut.

Turn the outer rose clockwise or counter-clockwise so that the gap between the rose and the nut is 1/8-inch if you have a 1 3/8-inch think door. If your door is 1¾-inches thick, adjust the gap to ¼-inch.

Insert the outer Yale door knob assembly into the door from the outside of the door. The door cylinder will fit through the latch assembly and out to other side of the door. The key cylinder should point up so the key is upside down when unlocking the door. Ask a friend to hold the outer door knob while you assemble and secure the door knob from the inside of the door.

Slide the inside retainer plate over the door knob cylinder and secure the plate. There are long threaded screws that you insert through the retainer plate into sleeves on the outer handle that are inside the door. Tighten the retainer plate screws with a flathead screwdriver.

Slide the rose plate for the inner knob over the door lock shaft and twist it onto the retainer plate until the rose locks into position. There is a small knob catch on the door lock shaft near the end of the rose plate. Press the knob catch flush to the knob shaft with the flathead screwdriver. Slide the inner door knob over the inner shaft past the knob catch, removing the screwdriver when the edge of the knob reaches the catch. Twist the knob slightly to engage the catch.

Close the door and attempt to set the deadbolt. If the deadbolt will not seat all the way to the lock position, you will need to make the current hole in the door jamb deeper.

Drill the hole deeper with a drill and 3/8-inch hole saw. Place the strike plate over the hole and secure the strike plate with the securing screws.
