A key-in-knob lock is a lock that is hidden inside a door knob and is opened with a key. The lock and barrel are built into the door knob. The keyhole is on the outside of the door.
There are many different ways to lock doorknobs and handles. Most front doors have pin tumbler cylinder locks that can be locked and unlocked with a standard house key.
The key goes into the door lock’s cylinder, also called the lock body. When the cylinder is locked, a set of pins that are held in place by springs keep it from turning. When a key is put in, the uneven edge of the body of the lock pulls the pins up to the height of the key in that part of the body of the lock. When the pins are in the right place, it knows which key to use. Then, by “opening” the cylinder, you can slide the bolt and open the door.
On a typical knob lock or lever set, you can see a key in the knob/lever cylinder. The cylinder holds together the part of the lock where you put your key. If you took the cylinder out of a standard keyway cylinder, it would look like the figure on the right. Depending on the brand of lock, it may be longer or shorter and have a different look at the end. The depth of the lever affects the depth of the cylinder, and the end is determined by how the cylinder works with the locking mechanism of the lever. Because interchangeable core levers and knobs are made differently, they can’t use the same cylinders.
The most common type of door lock on the market is the knob lock, which is also the main security feature on most doors. Instead of being within the door, the lock cylinder is inside the knob. Because knob locks are easy to open with a hammer or other tool, they shouldn’t be used on outside doors.

Most of the time, these are used in bathrooms and bedrooms to keep family members or roommates from accidentally coming in at bad times. They only have a lock on the knob and no key. But because they aren’t safe enough to keep people from breaking into your home, these locks shouldn’t be put on outside doors.
