A lot has been said about blacksmithing problems and their respective solutions yet so little about locks. Today we are going to explore the Four Types of Locks and the security factors to consider. This will help you decide which type of lock your home needs if you are interested in changing the locks in your home.
Knob Locks
Although these locks are not to be used for security on external doors, they are most frequently used as primary security or along with deadbolts. As one of the four types of locks, knob locks have a design where the locking mechanism or lock cylinder resides in the knob. This can be easily compromised by determined burglars using tools like a hammer, pliers, or a wrench. If knob locks are currently being used on your house’s external doors, you should consider replacing them. Simple passage knobs make a good replacement in this case. Use them along with deadbolts, and they will provide adequate security.
Deadbolts are among the most sought-after for external doors and are basically of three types: Single Cylinders, Double Cylinders, and Lockable Thumb Turn. These variations represent different solutions for security and convenience within the broader category of Four Types of Locks.
Single Cylinder: The easily recognizable features on this deadbolt are the tapered cylinder and rotatable thumb turn. However, they can be easily opened from the inside using the thumb turn.
Double Cylinder: Unlike the single cylinder, this version features two key cylinders—one on the outside and one on the inside. This helps solve the problem of being easily opened from the inside, which the single cylinder has. However, it requires a key each time the door needs to be opened from the inside, potentially slowing or halting escape in emergencies.
Lockable Thumb Turn: A mix of the preceding two deadbolts, the thumb turn can be left in an unlocked position if the room is occupied for easy opening from the inside. The thumb turn can also be locked if the house will not be occupied for an extended period, requiring a key to open the deadbolt from both the outside and inside.
Cam Locks
Cam locks, one of the Four Types of Locks, are most frequently applied in cabinets and mailboxes. The cams (otherwise called tailpieces) they feature are used to connect them with another locking mechanism. The cams come in different types and lengths, and are able to rotate in both directions of their axis at maximum angles of 90° or 180° depending on the type.
Euro Profile Cylinders
As the name partially suggests, these locks are frequently used in Europe. They are also used in other parts of the world. Four Types of Locks include the Euro Profile lock, which has three kinds: single, double cylinder, and single cylinder with thumbturn. These locks follow a fairly standard form of design. Although it has varying lengths of the exterior, the dimensions of other parts are quite standard. The problem with this lock is that it can be removed, though with some effort, owing to the fact that it is held in place by a screw that runs through the center of the cylinder. To prevent this, the lock has to be properly reinforced.
Of course, there are numerous types of locks, including the Four Types of Locks, and we will eventually cover them all. For additional info, you can always contact Alcatraz Locksmith. Call us at 602-677-5045.
