2. Tools Required:

    1. Power Drill
    2. Drill Bits - 10mm (⅜”) & 25mm (1”)
    3. Hammer/mallet
    4. Phillips screwdriver
    5. Chisel (1”)
    6. Stanley knife
    7. Adhesive tape, pencil, bradawl, tape measure
    8. Pilers and hacksaw for cutting bolts

3. Please Note: Your lock is shipped with a default user code of 1234 and default programming code of 123456. These should be deleted/changed immediately after installation for security purposes (instructions provided at the end of this installation manual).


1. Affix the Template:

To assist with holes that will need to be drilled for installation, use the provided template. Crease the template along one of the dotted lines (60mm (2 3/8”) or 70mm (2 3/4”) latch). Place the template on the door and position.

If you need a new installation template, please download the template here. PLEASE NOTE: When printing templates, check your print settings to make sure that the template is printed at 100% of the actual size. Once printed, check the measurements on the template with a ruler before drilling your door.

If a 2 1/8” boring hole already exists, ensure the template matches the existing hole by viewing from the other side of the door. Also, ensure that the center of latch line on the template is exactly centered over the latch opening on the side of the door.

Once the template is aligned, tape it to the door.

Mark the holes to be drilled. We suggest using a sharp object, like a nail or a thumbtack. Since the 2 ⅛” boring hole already exists in this example, only one additional hole needs to be drilled.

After marking one side of the door, apply the template to the other side of the door using the same methods above to ensure precision.. Mark the 10mm (⅜”) hole to be drilled again.

2. Drilling Holes

Keeping the drill level and straight, drill the holes in the door face. Drill half way through on the first side, then the remaining half from the other side to increase accuracy. This also avoids damage to the other side when a drill breaks right through.

Drill the remaining half from the other side of the door.

Your door should look something like this when finished with drilling.

3. Latch Installation

Latches come in two lengths, 2 3/8" (60 mm) and 2 3/4" (70mm). (This installation will be with the 2 3/4" (70mm) latch.)

Place the latch into the side of the door and ensure that the latch plate lays flush with the door. If not, draw around the faceplate edge. Next chisel a rebate to allow the latch to lay flush with the door edge. 


Once you have chiseled the rebate, use the provided screws to secure the latch in place.


4. Support Post

Next, we need to attach the latch support post. This will be screwed into either the left or right outermost hole. The hole that you will use will be dependent upon whether your door is a left hand or right-hand door.

Fit the latch support post on the inside of the front plate, in the outer hole of either the left or right side to match the support post slot in your latch. (In our example, our door is left hand hung so we have utilized the left outermost latch support post.)


5. Apply Gasket

Next, fit the self-adhesive gaskets on both the front and back plates. These gaskets provide friction against the door, so it is not necessary to over tighten when installing.

Simply pull the white plastic adhesive off the gasket and apply to the backplate of the lock. Be sure to align the holes up accordingly, so that the antenna and power cable fit through the provided holes. 


6. Install Spindle

Place the spindle into the latch with the spring on the keypad side (front) of the door. The spring ensures that the spindle remains in contact with the front of the lock.

Note: If you install the spindle with the spring on the back of the door, the lock will not work properly. 


7. Interior Lock Prep

Remove the battery cover from the back plate and remove the battery pack. Remove the screw that secures the battery cover.

Note: Apply pressure to the battery cover with your thumb and pushup to remove.


8. Lock Prep: Sizing Fixing Bolts

Cut the fixing bolts to the correct length. Measured from beneath the bolt head, the length should be the door thickness, plus approximately 1/2” to the nearest cutting point of the bolt.




Note: Always cut the bolts at one of the cutting points so as not to damage a thread. Use the cutting edges of pliers to crimp strongly several times around the selected cutting point.

9. Apply Lock Front

The front of the lock has two important cables sticking out of its backplate.

  1. One is the power cable that will be connected to the battery pack of the backplate.
  2. The other is the antenna, which provides wifi signal strength to the lock.

Please do not damage either of these, as they play an important role in your lock functioning properly. Apply the lock front over the spindle. First, pass the antenna and power cable OVER the latch.

Then press the lock up against the door, passing the latch support post through the latch and the power cable and antenna through the door.

Important: Be sure to pass the power cable and antenna above the latch in the door. If you pass these below the latch they will not be able to reach far enough into the back plate to attach to the battery pack and the plastic battery cover.

10. Apply Interior Lock

First, before installing the interior lock, roll the white adhesive of the antenna and place a small piece of scotch tape onto it to keep it rolled up. This will make feeding the antenna through the back plate easier.

Also be sure that the battery pack is removed, as it is not yet needed.

Feed the power cable and the antenna (with the rolled up white adhesive) through the hole above the main spindle hole. (Images below) Once they are through the hole, grab both wires and pull them up and out of the battery pack area.



11. Secure Interior Lock

With the power cable and antenna in hand, screw the fixing bolts through the interior lock to the front plate. Two screws are needed; one at the top of the lock and another on the bottom below the handle.

Note: Don’t screw the top screw in all the way, leave it a little loose, then screw the bottom in and tighten both (back and forth) until completely tight.


Important: Before moving forward we need to make sure that the lever and the latch are moving freely. Using the inside handle boss check that the spindle moves freely, and the latch retracts and projects smoothly. If it is too tight loosen the fixing bolts and adjust the position of the back plate until the spindle moves freely. Once this feels right, tighten the bolts.

12. Finalize Interior Lock Install

Next, we will install the batteries into the battery plate. Take 4 AA batteries and place into both sides of the battery pack.

Once batteries are installed, connect the power cable from the lock to the battery pack.

Next, place the battery pack into the back plate with the top of the battery pack sticking out. The top is where the cable is connected to the battery pack.

Note: Placing the battery pack in this way will make folding the excess cables easier.

Once the battery pack is inserted, store any excess power cable with the door. The antenna can be left alone for now, as it will be connected to the plastic battery cover.

Next, remove the white adhesive from the antenna, and stick the black antenna head to the inside of the black plastic cover. We suggest sticking it to the side furthest away from where the antenna originates.

Once this is complete, place the battery cover and screw it in.

13. Handle Installation -- Interior Lock

Using the Allen keys provided, unscrew the small screw from the inside handle, place over the handle boss, then screw the small screw in.

The backplate is done!

14. Handle Installation -- Front Lock

Repeat the same step with unscrewing the small screw in the outside handle.

Next, place the front plate cylinder cover over the front of the key insert, then place the handle over and screw into place.


Well done, installation of the lock is complete! Now onto connecting to your internet wifi!

The inside handle will now retract the latchbolt. The outside handle will turn freely without retracting the latch. Enter the factory default code 1234#. The keypad will flash blue and the outside handle will now retract the latch.
