Deadbolts and door handles are installed
How to install a door knob and lock is one of the most common queries we get from readers.
Because you don’t have to mortise the door or the door frame, changing existing door hardware is a simple process (like you would for a first-time installation).
If you know what you’re doing, installing a new knob or lock may take as little as 15 minutes.
Remove the old knob or deadbolt.
The removal of the old hardware is usually a simple procedure.
Most manufacturers will have two accessible screws on the interior of the unit.
You may now remove the internal and exterior components after backing them out.
A lock that required the key to be turned halfway before reaching the screws is an example of this, and the fasteners are often hidden behind secret releases or covers.
The latch or lock is typically fastened into the door’s end with two screws.
Once you’ve removed them, the latch should come loose.
To minimize difficulties with hole size/ spacing, it is beneficial to get new locks from the same manufacturer as the previous ones.
Whatever the case may be, you should be able to answer the following questions:
Is there one or two holes in the door?
What is the backset (the distance between the door’s edge and the hole’s center)? The backset is normally 2-3/8′′ or 2-3/4′′ wide.
What is the distance between the centers of the two holes on a two-hole door?
What is the diameter of the hole if you’re putting in a deadbolt? It’s normally 1-1/2′′ or 2-1/8′′ in diameter.
