What Types of Deadbolt Locks We Have?

The cylinder deadbolt lock is a type of home lockset that usually installed on the exterior doors, gate, or main entrance door in the house. Because in addition to the usual door knob locks and Lever Door Handle locks, the keyed deadbolt locks are usually needed to provide additional protection to ensure the safety and privacy of your family.

The cylinder deadlock must be needed as a key or a thumb turn to complete the door opening or locking operation. Usually, the deadbolt lock is opened and closed by the key from outside, and the door is locked by the thumb turn from inside.

There are two main types of cylinder deadbolt locks: single keyed deadbolt locks and double cylinder deadbolt locks.

Single Cylinder Deadbolt Locks

The single-cylinder interlocking deadbolt is the most common type of deadbolt. It is mainly installed on the main entrance interior door of the home and the door of high privacy. There is a thumb turn to open and close the door from the inside of the door, and only a key is used to open and close the door from outside of the door.

The single-sided keyed deadbolt locks are the simplest ones and can be activated from one side via a key, they can be found in most homes. But the single keyed deadbolt lock has an obvious shortcoming that if someone enters the room through the window, the door can be easily opened from inside.

Double Cylinder Deadbolt Locks

The double keyed cylinder deadbolt lock is also a lockset that can be installed inside of the home. The difference between single-cylinder and double-cylinder deadbolt lock is that there is no twist or thumb turn inside the door, and there is a key cylinder on both sides of the door. Whether you are inside or outside the door, you always need a key to open the door.

The obvious disadvantage of double-sided key deadbolt is that if the door is locked, a key is always needed to open the door. In the event of a fire or other emergency, it will take more time to find and use the necessary keys, which may cause serious problems.

So if double cylinder deadbolt locks are used in a residential environment, it is strongly recommended to leave the key inside of the room to ensure safe exit in an emergency.
