Different combination lock system and their mechanism
                     DIFFERENT COMBINATION 
LOCK SYSTEM AND THEIR 
MECHANISM
MEI LOCK
A combination lock is a type of lock that opens with a series of 
numbers or symbols rather than a key. The sequence of numbers 
or symbols used is frequently a permutation rather than a true 
combination, and they can be inputted using a single rotation 
dial or a collection of revolving discs with inscribed numbers or 
symbols (which directly interact with the locking mechanism 
itself).
Combination cam locks systems which are relatively affordable, 
are used for a variety of functions. These locks usually contain 
simply three numbers or letters as a combination. Safes, notably 
those in banks, have more complicated combination locks, 
which require a locksmith to be extremely competent to unlock. 
The mechanism works by engaging with the locking device using 
numerous rotating discs and cams.
MULTIPLE DIAL 
LOCKS: 
We'll start with multiple dial locks, which are one of the most basic types of 
combination locks. These are frequently employed in low-security scenarios, 
such as a bicycle lock with numerous revolving discs cut into notches. The 
lock is held in place by a pin with many teeth that latch into the rotating 
discs around it. The lock can open when the discs and notches are aligned 
with the pin's teeth. Unfortunately, this form of lock has the problem of being 
one of the least secure forms of combination locks available today.
It is possible to unlock such a lock without using the combination; it all 
depends on little imperfections that arise during the machining of the lock's 
pieces. So, unless the lock has been perfectly machined (the pin forced 
outward), one of the teeth on its matching disc is likely to pull more firmly 
than the others.
When this disc is turned and a little click is heard, the tooth has moved into 
its proper notch, and the technique can be repeated with the remaining discs 
to unlock the lock (a correct combination on such a lock can be found in a 
very short period)
SINGLE DIAL LOCK: 
The next type of lock is the single-dial lock, which is typically found 
on padlocks or safes and consists of a single dial that interacts with 
many parallel discs or cams. Normally, such locks are opened by 
rotating the dial clockwise to the first numeral, then counterclockwise 
to the second, and so on until the last numeral is reached.
The cams inside the lock usually have an indentation or notch on 
them, and the latch can only fit into them and the lock may be opened 
once the right combination has been input and the notches or 
indentations have gotten aligned.
These types of combination locks are unquestionably more secure 
than multiple dial locks, but they do have certain drawbacks. 
Certainly, early Master Lock combination padlocks could be opened 
by pushing on the shackle and rotating the dial until it stopped, 
revealing each digit included in the lock's combination.
MASTER PADLOCK
However, more current variants of the Master padlock now 
have a 40-position dial, which has a flaw in that it reveals the 
last numeral in the lock's combination, and the lock's initial 
two numbers have a mathematical relationship with this one. 
Because of this flaw, it decreases the number of possible 
combinations a person can try to open it from 64,000 to just 
100, which makes it difficult to open.
Unfortunately, an inexpensive padlock isn't the answer, as 
they're prone to be shimmed, which is a method of releasing 
the shackle without actually entering the combination.
OTHERS
There are many other combination lock and door lock systems that 
require the user to enter a numeric sequence on a keypad to gain 
admission. However, to be successful, such locks usually require the 
usage of electronic circuitry. However, the main advantage of such a 
system is that if it is used for the entrance to a large workplace, each 
member of staff may be given the number they will need to obtain 
access, eliminating the need to present them with keys that may be lost 
or stolen.
The only significant downside of this form of lock is that if the code 
number for entrance is found by someone who isn't a firm employee, or 
if the number isn't updated regularly, an intruder can get access to the 
property (such as a burglar).
