Why are skeleton keys called skeleton keys?

The term ‘skeleton key’ derives from the fact that the key has been reduced to its essential parts.

However, the name often refers to any antique key, no matter how ornate. As long as there is a bow, a narrow shank or shaft, and a flat extension on one side near the bottom of the shaft, a key is often considered a skeleton key.

How does a skeleton key work?

Skeleton keys can work with warded locks or lever locks.

With a warded lock, a skeleton key lacks interior notches to interfere with or correspond with the wards, or obstructions, thereby allowing it to open the lock.

In a lever lock—that is, a lock with a set of levers and wards—the skeleton key can push the levers to the correct height while bypassing the wards. In this type of system, each lock will still have its own key that corresponds with the wards; the skeleton key, or master key, can open any of the locks within that system. (You may find these locks at hotels, office buildings, schools, or apartment buildings.)

Are all skeleton keys the same?

Although a skeleton key is a “master key,” not all skeleton keys are the same. The size and cut of the key’s bit, as well as the diameter of its barrel, determine whether it fits with a lock. Additionally, antique (or reproduction antique) skeleton keys are known for their intricate details.

What does a skeleton key symbolize?

Skeleton keys symbolize “access to” something, whether it be abstract, as in “keys to a city,” or actual, as in the key to your home. They are often thought to symbolize the key to one’s heart, the key to success, or the key to “unlocking the door” to whatever it is one wishes to attain.
