So August — which, for now, ships in the U.S. — is launching a new smart lock that cooperates with Mortise locks.

|
The initial Latch lock, which launched last year, works with mortise locks and includes a physical handle and slot for an actual key.
|
|
Where the Latch M was built for tall mortise locks, the Latch C is meant for simpler cylindrical deadbolts, which aren't attached to the knob.
|
|
The Latch C is designed to be installed on individual apartment doors that are equipped with a deadbolt, whereas Latch's first product, the Latch M, works with mortise locks.
|
|
Certainly for now (although the Latch team reckons there's no barrier to rolling their product out internationally in future, in markets such as Europe and China where mortise locks are also common).
|
|
With all three products co-founder Luke Schoenfelder says Latch is able to address a full spectrum of multi-unit and residential buildings across the U.S. — noting, for example, that "in some geographies, particularly in the American south and in some places in California, they use deadbolts in apartment buildings more than they use mortise locks".
|
|
So while the Latch M works with mortise locks — and includes a physical handle and slot for an actual key, for people who prefer the traditional key-in-hand route to gain entry — the Latch R enables purely electronic entry — either by tapping a mobile or key card or tapping in a code on its touchscreen.

Jefferson ordered his locks from Paris. Similarly, mortise locks were used in primary rooms in 1819 at Decatur House in Washington, D.C. while rim locks were used in closets and other secondary spaces. Warded lock mechanism, only rarely used for mortise locks, owing to the depth required The mortise locks used at Monticello were warded locks. The name warded locks refers to the lock mechanism, while the name mortise lock refers to the bolt location.

The type commonly called a 'Yale' lock. Mortise locks have historically, and still commonly do, use lever locks as a mechanism. Older mortise locks may have used warded lock mechanisms. This has led to a popular confusion, as the term 'mortise lock' is usually used in reference to lever keys.

Mortise locks have been used as part of door hardware systems in America since the second quarter of the eighteenth century. In these early forms, the mortise lock mechanism was combined with a pull to open the unlocked door. Eventually, pulls were replaced by knobs. Until the mid- nineteenth century, mortise locks were only used in the most formal rooms in the most expensive houses.
|
|
Other rooms used box locks, or rim locks, in which, unlike in mortise locks, the latch itself is in a self-contained unit that is applied to the outside of the door. Rim locks have been used in the United States since the early eighteenth century.Schiffer, Herbert. Early Pennsylvania Hardware.

Box E. Exton: Schiffer Publishing, Inc., 1966. A rim lock has the lock body and bolt mechanism on the outside of the door, unlike a mortise lock, where the bolt is inside the door. An early example of the use of mortise locks in conjunction with rim locks in one house comes from Thomas Jefferson's Monticello.

Mortise locks may include a non-locking sprung latch operated by a door handle. Such a lock is termed a sash lock. A simpler form without a handle or latch is termed a 'dead lock'. Dead locks are commonly used as a secure backup to a sprung non-deadlocking latch, usually a pin tumbler rim lock.

In 1805, Jefferson wrote to his joiner listing the locks he required for his home. While closets received rim locks, Jefferson ordered twenty-six mortise locks for use in the principal rooms. Depictions of available mortise lock hardware, including not only lock mechanisms themselves but also escutcheon plates and door pulls, were widely available in the early nineteenth century in trade catalogues. However, the locks were still expensive and difficult to obtain at this time.

Furthermore, a mortise lock typically accepts a wide range of other manufacturers' cylinders and accessories, allowing architectural conformity with lock hardware already on site. Some of the most common manufacturers of mortise locks in the United States are Nostalgic Warehouse, Accurate, Arrow, Baldwin, Best, Corbin Russwin, Emtek Products, Inc, Falcon, Penn, Schlage, Sargent and Yale. Also, many European manufacturers whose products had been restricted to "designer" installations have recently gained wider acceptance and use.

A mortise lock (also spelled mortice lock in British English) is a lock that requires a pocket—the mortise—to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. They are widely used in domestic properties of all ages in Europe.

In recent years the Euro cylinder lock has become common, using a pin tumbler lock in a mortise housing. The parts included in the typical US mortise lock installation are the lock body (the part installed inside the mortise cut-out in the door); the lock trim (which may be selected from any number of designs of doorknobs, levers, handle sets and pulls); a strike plate, or a box keep, which lines the hole in the frame into which the bolt fits; and the keyed cylinder which operates the locking/unlocking function of the lock body. However, in the United Kingdom, and most other countries, mortise locks on dwellings do not use cylinders, but have lever mechanisms.

Just two years later, Hiram S. Shepardson produced a different type of wafer tumbler lock, which used a single-bitted flat steel key, similar to Yale's feather key. By 1878, Yale Lock had purchased Shepardson's company, The United States Lock Company, as well as Felter's American Lock Manufacturing Company. For the next 35 years, production of wafer tumbler locks languished in the U. S. And while Felter and Shepardson had designed their wafer tumbler locks for a variety of applications such as drawer and desk locks as well as padlocks and door locks, the wafer tumbler locks made during this era were mainly used for doors in mortise locks and night-latches. Emil Christoph developed a wafer tumbler lock in 1913 which used a double-bitted key.
