Step 1: Prepare all the parts in advance
If you package is complete, then it should contain the following parts:
- Exterior Assembly
- Mounting Plate
- Interior Assembly
- Drive-in Sleeve
- Wood screws 5 pcs
- Machine screws 3 pcs
- Mounting Plate screws 2 pcs
If you are not sure what these parts look like, you can refer to the following figure:
Step 2: Latch Adjustment
Determine if the latch needs to be adjusted to the 2-3/4" (70 mm) backset.
If you want to adjust, rotate the latch until it stops.
Reverse the direction to return to the 2-3/8" (60 mm) backset.
Step 3: Backset Determination
Backset is a distance from door edge to centre of hole on door face.
Adjustable latch fits both backset of 2-3/8" (60mm) and 2-3/4" (70mm).
Step 4: Mark the door with template
Select the height and backset as desired on the door face;
Use the TEMPLATE as an indication to mark the centre of the circle on the door face and the centre of the edge.
Step 5: Drill holes
Using the marks as a guide to drill a hole (54mm) through the door face for the lockset, then a hole (25.4mm) for latch.
Step 6: Install Latch
- Insert the latch and ensure it is parallel to the door face.
Mark the outline of the faceplate, then take out the latch.
- Chisel 5/32" (4mm) deep along the outline to allow the faceplate to be aligned with the door edge.
- Insert the latch into the door. Use 2 wood screws to secure latch.
Note: Please do not fully tighten the screws until lock is completely installed.
- Install Drive-in Latch. Drive the latch into the hole on edge of door.
Step 7: Install strike
- To identify the centre of strike: close the door to lay the latchbolt against the door frame.
Mark the centre line on the doorframe exactly opposite the latch hole in the door edge.
- Measure one half of door thickness from door step and vertically mark centre line of strike.
Drill 1"(25.4mm) hole, 1" deep at intersection of horizontal and vertical line of strike.
Chisel 5/64(2mm) deep along the strike outline to allow the strike to be aligned with the doorframe.
- Install the strike plate into your door frame and tighten with wood screws.
Step 8: Install keypad assembly
Install cylinder into the deadbolt keypad assembly with tailpiece in horizontal position inserted through hub of the latch.
Pass the IC wire under the latch to the interior side of the door.
Step 9: Install inside mounting plate
Pass the IC wire through the wire hole of the mounting plate.
Fix the mounting plate with screws.
Note: If outside lock assembly is lopsided, please loosen the screws to adjust its position and tighten the screws again.
Step 10: Identify door handing
Face the door from the outside.
The door is left-handed if the hinges are on the left side of the door, whereas the door is right-handed if the hinges are on the right side of the door.
Step 11: Adjust thumb turn piece
Rotate the thumb turn piece to the LEFT at 45°for right-handed doors.
Rotate the thumb turn piece to the RIGHT at 45°for left-handed doors.
Step 12: Install receiver module
Remove the battery cover (push it up first then pull it out).
Connect the IC wire into the back of the receiver module.
Ensure that the deadbolt tailpiece is engaged with turn piece, then attach receiver module to the door with screw.
Use the optional wood screw to secure the receiver module to wood doors only.
Step 13: Insert batteries
Insert 4 (AA) 1.5V alkaline batteries and slide the battery cover back onto the receiver module.
- Alkaline batteries are recommended in order to stabilize the power supply.
If you don't use alkaline, battery performance will be reduced greatly.
- All settings will be retained in the memory even if the batteries are completed dead.
