Nothing quite says “I care for you” as being (appropriately) concerned over your girlfriends well-being. If her ex won't return the spare key or she's just moved into a new place, seize the opportunity, and offer to change out her door locks so she feels safe and secure. Replacing a lock or deadbolt is an easy project, and she'll love you for it.
Before you start, check out the current setup, and save yourself some trouble by purchasing a door knob or deadbolt of the same brand. It'll help ensure everything fits the way it should. Also, grab a Phillips and flat-head screwdriver. Removing the old hardware can seem like a puzzle, and sometimes you'll even need the key. Usually, there are hidden / inconspicuous screws or releases. Once you get the outer shell off, the screws should be obvious, and the lock will come apart quickly.
Changing a Deadbolt
Start by inserting the deadbolt into the door end. Most deadbolts will have a “this end up” arrow stamped on the side that will let you know how it should be oriented. Also, the deadbolt may have an adjustable backset (the distance between the edge of the door and the center of the hole), and depending on the manufacturer, you'll need to rotate the deadbolt, move a pin or loosen a screw. Backset lengths are typically 2-3/8″ or 2-3/4″.
Once you have the deadbolt screwed in, slide the outer cylinder in place. You can see that metal sleeve is there too.
The inner cylinder screws on with the silver metal plate underneath. Follow this up with the faceplate.
Some manufacturers (like Kwikset) make you tighten this uber-tiny set screw to hold the thumb-turn in place. Lastly, screw the strike plate onto the door jamb (door frame).
Installing a Door Knob
Installing a door knob isn't so different from a deadbolt. Start with the latch, and check that the backset is right. Also, make sure the face of the latch will hit the strike plate (and not the backside of the latch).
Put the outside knob on, feeding it through the latch.
Now, slide the inside knob on and tighten down the two screws. Finish it off by installing the new strike plate.
That's it! This is a 15 minute project that'll be sure to win you some points with your significant other.
