Keyed Door Knobs
Door knobs are a common version of keyed entry hardware, offering traditional design and operation. They feature a latch that disengages when you turn the knob. Locking the knob prevents the latch from being disengaged from the outside without a key. The inside portion of the knob has a thumb turn to lock and unlock the door knobs online. Some models feature easy-to-use push-button locking on the inside and locks that disengage when you turn the inside knob.
Keyed Door Levers
Door levers are designed for easy operation; they don’t require the grasping and twisting motion of knobs. Pushing the lever down disengages the latch. As with knobs, locking the lever prevents the latch from being disengaged from the outside without a key. The inside portion of the lever has a thumb turn or push button that allows you to engage the lock. Some models disengage the lock when you manipulate the inside lever, offering a simpler means of exit.
Door levers are left-handed, right-handed or universal. To determine what you need, look at the Door Pull handles from outside the house or room. If the hinges are on the left, look for a left-handed or universal lever. If the hinges are on the right, you need a right-handed or universal model.
Keyed Deadbolts
Deadbolt locks create a second locking point for your door when paired with a locking knob or lever, giving you an additional measure of security. Some knob and lever sets include deadbolts. There are two types:
Single-cylinder deadbolts require a key to unlock from the outside but unlock with a small knob or thumb turn on the inside. They’re good for doors that don’t have glass that can be broken to allow operation of the knob from the outside. The design allows you to unlock a door and exit your home more quickly in the event of an emergency since you don’t have to locate the key.
Double-cylinder deadbolts require a key to unlock from the outside and the inside. They improve security if the door has glass near the Mortise handle lock, but they can take longer to unlock and are prohibited in some areas for some types of buildings. If you use a double-cylinder deadbolt, keep a key in a designated location for easy access in an emergency.
Keyed Handlesets
Handlesets add a bold, decorative touch to an entry door. They include an exterior handle, a thumb-operated latch and a matching deadbolt. A knob or lever operates the latch from the inside. You can find handle-sets with right-handed, left-handed and universal levers. The included tower bolt online may be single- or double-cylinder, depending on the model. Manufacturers may offer matching, non-functional (dummy door handle sets to complement the functional hardware on a double door. If you’re replacing a handle set, look for adjustable models that make it possible to use the existing installation holes in the door.
Other Door Hardware
There are different types of door hardware available to improve security: Door and door jamb security hardware strengthen vulnerable areas of a door and door frame, making it more difficult for an intruder to kick in the door. Door viewers, sometimes called peepholes, are sets of lenses that install in an exterior door to give you a wide-angle view of the outside. Night latches help secure your door tower bolt and can only be operated from the inside.
Door Hardware Finishes
Door hardware is available in finishes to match or help define your home décor. Polished brass finishes work with many home styles, and you can find pewter and brass finishes designed to provide an antique appearance. Look for brushed metals for a contemporary look and chrome hardware for modern appeal. Some finishes are designed to change their appearance with wear.
