Tools Required:

  1. Power Drill
  2. Drill Bits – 10mm (⅜”)
  3. Phillips screwdriver
  4. Chisel (1”) *If the door is not prefabricated for the latch and strike
  5. Adhesive tape, pencil, thumbtack, tape measurer
  6. Pliers or bolt cutters *If the provided pre-cut mounting bolts do not fit your door and you need to cut the additional bolts to length.

3i Installation Instructions:

1. Affix the Template:

Use the provided drilling template to mark the upper 10mm support hole and prepare the door for drilling.

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.

Start with an empty doorknob and latch hole.


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 it perfectly over the boring and latch holes.


Ensure the template is flush with the door and the lower 10mm support holes are centered in the boring hole. View the template from the other side of the door to make sure it is center and the latch line on the template is exactly centered over the latch opening on the side of the door.


Once the template is aligned, and measurements have been double checked, tape the template to the door.


Mark the center of the upper 10mm hole 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, and the lower support bolt will go through the boring hole, only the upper 10mm hole will need to be drilled.



After marking one side of the door, apply the template to the other side of the door using the same methods. Make sure the holes are aligned exactly from one side of the door to the other and double check all the measurements to ensure precision.

Mark the center of the 10mm (⅜”) hole to be drilled.

2. Drilling Holes

Prepare your power drill with the 3/8″ drill bit.


Keep the drill level and straight, align the drill bit over the indentation and hold the door steady. Drill half way through on the first side, then the remaining half from the other side of the door. Drilling the hole halfway through each side of the door avoids blowback damage to the door and increases accuracy.


After drilling halfway through one side of the door, drill the remaining half from the other side. Make sure the drill is level, straight, and aligned over the marked indentation.

Your door should look like this after the hole has been drilled.


3. Latch Installation


Latches could come in two lengths, 2-3/8″ (60 mm) and 2-3/4″ (70mm).

This installation will be pictured with the standard 2-3/8″ (60 mm) latch.

Place the latch into the side of the door with the deadlocking plunger facing the exterior (keypad) side of the door. Make sure the latch plate lays flush with the dols81_left_right.jpg

or. If the latch plate is not flush in the door, draw an outline around the faceplate edge and chisel a rebate to allow the latch to lay flush with the door edge.


Use the provided wood screws and a Phillips head screwdriver to secure the latch in place.



4. Insert Spindle into Latch

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.




5. Screw the Latch Support Post in place

Next, we need to attach the latch support post to the lock. This post will be screwed into either the left or right hole closest to the center of the lock (for 60mm latch). The hole that you will use will also depend on 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.)

6. Apply Gaskets

Fit the self-adhesive gaskets on the back plate of each side of the lock.

* You may want to take a picture of the ‘RemoteLOCK’ 3i serial number sticker

Pull the white plastic adhesive off the gasket and apply to the backplate of the lock. Be sure to align the edges and pull the antenna and power cable through the appropriate hole.




Put the other gasket on the other side of the lock.


7. Interior Lock Prep

Remove the screw that secures the battery cover, then remove the battery cover and the battery pack.







8. Fixing Bolts

Use the correct length fixing bolts depending on your door thickness. Two different sized fixing bolts are provided as well as two bolts with various cut points to customize the bolt length.

Using one the pre-cut bolts, place one of the bolts through mounting bolt hole on the battery pack side of the lock. Hold the lock flush with the door but allow the bolt to pass along the edge of the door to gauge its length. The bolt should go about a 1/2″ past the edge of the door.

17-bolt-cut.jpgIf you need to cut the fixing bolts to the correct length – measured from beneath the bolt head, the bolt length should be the door thickness, plus approximately 1/2” to the nearest cutting point.




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. If the cut produces a sharp point, please sand the tip of the bolt to smooth it out.

9. Apply Lock Front (Keypad side)

The front (keypad side) of the lock has two important cables sticking out of its backplate. It has a power cable and a Wifi antenna which will be connected to the battery pack on the other side of the door. Do not damage either of these cords!

Pass the antenna and power cable over the latch, align the support post through the hole in the latch, and ensure the spindle plugs into the lock’s hub.




10. Apply Lock Interior (Battery pack side)

If you have an adhesive wifi antenna, 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. (If you have a gold wifi antenna you do not need tape).

Be sure that the battery plate and battery pack are removed from the lock housing.





Feed the power cable and the antenna through the hole above the main spindle hole (images below). Once the cords are inside the lock, grab them and pull them up and out of the battery pack lock housing.


11. Secure Interior Lock

With the power cable and antenna coming through the lock housing, place the fixing bolts through the lock to connect both sides and then tighten.

Both screws are needed; one at the top of the lock (through the drilled hole) and another on the bottom of the lock (below the handle going through the boring hole).

Note: Leave the top screw partially loose before then screwing in the bottom. Then tighten both screws (back and forth) until completely tight.



Now that both sides of the lock are mounted to the door, 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, re-tighten the bolts.


12. Install Battery Compartment and Connect Power

Put 4 AA batteries into the battery pack.


Connect the power cable from the lock to the battery pack by connecting the two plugs. You should hear a click sound when they connect.


22-wiring-2.jpgStuff the power plug back into the very bottom of the lock housing and push the wire to the side (leaving room for the battery pack and without obstructing the battery cover plate railings).

Put the battery pack back into the lock housing with the top wires facing out. Make sure the battery pack fits securely in the lock housing and none of the wires are in the railings. It will be a snug fit.


23-wire-placement-3.jpgNow slide the battery pack back into the lock housing with the top wires facing out.

The wifi antenna can be left alone for now, as it will be connected to the plastic battery cover.

If you have an adhesive antenna, 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.

Connect the gold wifi antenna to the battery cover plate by clicking it in place.



Slide the battery cover back on the lock and screw it in.

13. Handle Installation

Using the provided Allen key, loosen the small screw.

Place the key cylinder cover in place.


Slide the handle over the handle boss and tighten the handle screw. Make sure you’re holding the handle securely in place.


Repeat the same steps from above for the interior handle.

Loosen the small screw and place the handle over the handle boss. Tighten the screw while holding the handle securely to the boss.


Well done, installation of the lock is complete!

The inside handle should retract the latch bolt.

The outside handle should turn freely without retracting the latch.

Enter the factory default code 1234* to unlock the lock. The keypad will flash blue and the outside handle will now retract the latch. Auto lock is enabled and the lock will relock after 5 seconds (all these settings can be configured in the portal after connecting your lock to wifi). To lock the lock from the exterior, enter * *.

Please note, for security purposes, the default 1234* access code will be deleted after 24 hours or after the first access user is created.
