Some people theoretically say that a combination lock works in the same way as a lever
mechanism. Therefore, for a fence to retract, the tumblers in the lever mechanism must
align. It can cause the bolt to open, which in turn causes the lock to open. However, a
combination lock works similarly to a keypad lock; only it uses characters, numbers, or
symbols instead of keys. You can also read more about how to reset a combination
lock.
Components of a Combination Lock
First, we can discuss that a standard combination lock operates according to a set of rules.
Anyone can open it without using a key by the proper alignment of its parts in a specific
position. The most typical configuration of these locks is a collection of interconnected
rings or discs operated by a central shaft.
For the lock to open, you must align the rings. Moreover, the function of a combination
lock is far from straightforward. Moreover, before we can grasp how a combination lock
works, we must first discuss various components. Now, you can secure the locks more by
getting the service of an emergency locksmith in Melrose Park. We take a close look
at the many parts of a standard combination lock.
Combination Dial
The combination dial is an integral part of the combination lock. The dial is located on the
combination lock’s face. Furthermore, there are countless numbers, letters, and symbols
in the combination dial. It will help if you twist it in a precise way to unlock the
combination lock. Therefore, you also have to align the numbers perfectly.
Wheel Pack
Almost every lock has a wheel pack. In combination locks, the wheel pack is one of the
most general components that people utilize. The wheel pack has been around for almost
a century. Therefore, a wheel pack is a collection of wheels that work together to
determine the lock’s combination.
The wheel pack is set to detect the password and work following it. The number of wheels
in each combination lock varies. You can guess the number of rotations by the count of
numbers used in the correct combination.
Let’s look at the number 5678 as an example. In this case, there are four digits in the
combination. As a result, the wheel kit will have four wheels.
Spindle
A spindle is attached to the combination dial. Moreover, a spindle acts as an axis for
rotating objects because it is like a rod. However, the spindle connects the dial and the
drive cam. The spindle runs through all of the wheels and connects to a drive cam in the
back.

Drive Cam
Drive Cams are found in practically every mechanical combination lock available on the
market. They are metal or plastic discs that are round in shape.
They are installed in the lock’s rear. Typically, drive cam lays on top of one another. The
drive cam connects the top of the cam to a drive pin.
The drive cam’s primary purpose is to transfer any movement on the dial to the wheels.
The unlocking procedure will not take place if the driving cam does not transfer motion to
the wheels.
Drive Pin
Drive pins joined to the top of the drive cam, as previously stated. The pins are used to fit
into holes that have already been created. However, they serve as a locking pin,
preventing the driving cam from moving. The drive pin must make contact with a wheel
fly for the opening process to work.
Wheel Fly
Each wheel consists of a wheel fly. A wheel fly is a little tab that can find on each side of a
single wheel. It’s similar to a latch or a slot on the wheel’s side. The places appear at
specific positions on a wheel. The passcode of the lock determines these positions. The
primary function of this slot is to support drive pins.
Fence
The fence is also an essential part of the combination lock. A tiny metal bar serves as the
fence. Now, this metal bar rests on the lock’s wheels. First, the bolt that secures the lock
must open for the combination lock to open. After that, the fence stops the bolt from
opening by laying on the wheels. Now, the fence needs to align with the wheel fly to open
the lock.
Notchl
Each wheel has a notch in addition to a drive pin. These notches work in an alignment to
open the lock.
