Knob Locks

Knob locks are found throughout residential units as the primary locking system for both interior and exterior doorways. Both sides of the lock have a rotatable knob that is turned to open the door. One knob contains a key cylinder that controls the locking mechanism. While knob locks are popular, they are very easy to break into either with brute force or the use of lock picks. They should always be accompanied by a second locking mechanism for additional security.

Lever-Handle Locks

Lever-handle locks are common in commercial buildings. Their structure is similar to knob locks, but instead of spherical knobs the handles are long levers that can swing up or down to release the door bolt. This makes them easier to open for nearly all residents and potential customers. Some models include a system that prevents the levers from being moved when the locking mechanism is activated.


Deadbolts are the most common front door lock in homes and businesses alike. Most are used in conjunction with a knob lock or other mechanism to provide an additional layer of security. Deadbolts use a rotating cylinder or thumbturn to drive a solid metal bolt into the door frame. The thumbturn is located on the interior side of the door, with a keyhole facing outside. These locks are particularly resilient to brute force attempts but can be opened by an experienced lock picker, given enough time.
Alternative varieties include:

  • Double deadbolt: Both the inside and outside faces of the lock feature a keyhole. A key is locked to open or close the door from either side.
  • Jimmy-proof deadbolt: Commonly found in older apartment and double doors, this lock uses two vertical bolts that fall into a strike plate instead of the standard single bolt that slides horizontally into the doorjamb.

Keyless Entry Pads

In our increasingly digital world, electric locks are becoming more common. Most electronically controlled locks are simply deadbolts that require a code instead of a physical key. Keyless entry pads usually require a particular PIN, but more expensive models use a card or finger-scan system to validate entry. All keyless entry pads should be installed by a professional technician to ensure the electronic mechanisms work as intended.

When asked to describe a key, most people would probably resort to describing an ornate, vintage key or the variety they’d use on their home’s front door. However, many do not realize there are a wide variety of keys available on the market. Although these keys serve the same general purpose, each is cut using different techniques and are best suited to different locks.

Sunk Keys

Often used in heavy machinery or automotive work, sunk keys are a type of key that utilizes a specific metal shape to insert into a key shaft of exactly the same shape and size. Sunk keys are available as rectangular sunk keys, square sunk keys, parallel sunk keys, gib-head keys, feather keys or woodruff keys.

Each of these types is shaped slightly differently and cannot be interchanged between keyholes. For example, a square-shaped sunk key cannot be forcibly inserted into a tapered keyway.

Saddle Keys

Saddle keys are comprised of two sections that fit perfectly into a keyway. In a flat saddle key, the shaft of the key has a recess that fits a flat, rectangular member. When the shaft with the member is inserted into the keyway, the precise shape of the keyway holds the member in place. In hollow saddle keys, the shaft is completely smooth and cylindrical, while the member is rectangular with one carved-out, curved side to perfectly match the curve of the shaft.

The cylindrical shaft is inserted into the keyway and the member slides into a recessed keyway along the shaft, holding it in place. Saddle keys can fall out of the keyway with enough movement, so it is recommended these keys be used for light-duty work.

Tangent Keys

Tangent keys are typically used in heavy-duty work. These keys tend to be rectangular or wedge-shaped. There are one or two recesses carved into a metal shaft. The tangent members are placed into the recesses at an angle, allowing one edge to lock into the shaft and another to extend out past the shaft.

Once these tangent members are placed, the key is inserted into a keyway that is the exact shape of the key with one or two negative recesses to accommodate the tangent members.

Round Keys

Round keys are fairly common in light-duty work. On the cylindrical metal shaft of the key is a small drilled recess that accommodates a rounded, protruding section. The entire key is placed into the keyway, sized to fit the cylindrical shaft and a pathway for the protruding section. The key is typically turned to lock into place.


Splines are a slightly more complicated variety of key usually used in gear machinery. While they still include a metal shaft, a section around the outer circumference of the shaft is formed into small teeth. The teeth like structures lock into the keyway and provide torque while turning the key.
