Things You'll Need:
- Fingerprint door-lock kit
- Screwdriver set
- Hammer
-
Step 1
Buy a kit and make sure all of the parts are in it. Notify the manufacturer if any parts are missing.
-
Step 2
Drill holes in the door. Depending on the particular lock you purchased, you will need to drill some holes in the door and door frame. You will need a minimum of one hole into the side of the door about two inches deep to fit the deadbolt in and another hole the same diameter in the door frame for the deadbolt to lock into.
-
Step 3
Adjust the deadbolt to fit on the lock mechanism by putting a screwdriver into the driver board hole and turning until it is set where you need it. Dead bolts retract far enough into the door to allow the door to open when unlocked and to extend far enough to ensure a tight seal when locked.
-
Step 4
Install the latch, deadbolt and strikes. The door latch and deadbolt have faces that sit on the edge of the door. Insert screws into the holes and tighten them up against the door. Hammer the metal plates, called strikes, into the holes in the door frame that you drilled for the latch and deadbolt to protect the frame from damage.
-
Step 5
Install the lock mechanism. You will usually need to place the lock mechanism with the fingerprint window on the outside of the door. Hold it in place while placing the back plate on the inside of the door. Draw the two pieces tight to each other with screws.
-
Step 6
Check that the latch and lock function in their arrangements. The door should create a tight seal with the door frame. Try out the mechanism and make sure everything matches up before inserting the batteries and starting up the new lock.
