Lock Set ‐ What to Look For
A lock set is a complete locking system for a door. It incorporates all the components needed for installation and use of the locking mechanism. Lock sets can be found at virtually any store that sells home improvement items, including hardware stores, home improvement warehouse stores, and even discount retail chain stores. Prices range considerably for lock sets, but keep in mind that you get what you pay for. Selecting a grade-1 or grade-2 lock set, as classified by the American National Standards Institute and the Builders Hardware Manufacturers Association insures that you get the best possible lock for your money.
The two most common types of lock sets available are the mortise and the cylindrical lock set. Both, when purchased in a retail store, should be relatively easy to install with a little time and patience. The set comes with a paper template that allows you to match the holes you need to make with the edges of the door and the door frame to get the best fit. Tools to have on hand to install your own lock set include tape, a pencil, a power drill with a hole-saw attachment, a combination square, sandpaper, a chisel and a screwdriver.
When purchasing a lock set, look for those made from high quality stainless steel and brass for maximum strength. For a nice finish, choose one that is plated in brass, bronze or chrome. Another variable to consider is whether you’re putting the lock on an interior or exterior door. Interior lock sets come with knobs of various shapes, and some have privacy locks (a pushbutton lock) on one side. These are generally used on bathroom or bedroom doors. Exterior or entry locksets are heavier, more durable and more secure, and come in various configurations. For example, some have a standard keyed entry, while others have an emergency exit knob (which can be opened from inside without unlocking the latch) or a dummy set (a fixed knob that is paired with an active one).
Another variable found in lock sets is the way in which they are opened. Examples include those which can be opened from both sides and locks that use a key, a button, or a throw latch
Exterior or entry doors require the highest level of security, and a basic lock set may not provide enough since they generally don’t come with a deadbolt. For extra security on an exterior door, pair the lock set with a deadbolt made of case-hardened steel.
