What types of locks are there?

Locks are a great way to keep your belongings safe from people who don’t have permission to access them. They come in all shapes, sizes, and functions and can be used for everything from securing your home to keeping your bike safe on campus. There are several different types of locks that can help with all these tasks:

Pin tumbler locks

Pin tumbler locks are one of the most common types of locks. They can be found on things like door locks, padlocks, and even vending machines. These locks usually consist of a cylinder with pins that are arranged in grooves around it. If you want to open the lock, you need to insert the right key into it and turn it. This will push all of the pins up so that they line up with holes in your key and thus allow you access.

A pin tumbler lock is made up of the barrel – this is what holds all of your pins in place while they aren’t being used, and the pin stack – these are made up of an outer shell that contains two chambers that each have one end cut at an angle (this allows them to fit into notches on either side).

Wafer tumbler locks

Wafer tumbler locks are unique in that the key itself is comprised of three thin, flat metal plates. Those three plates are called wafers, and they fit into a very specific opening in your lock. Each wafer has a cutout with an “X” shape at the center to match up with another wafer inside (which can either be left alone or moved into place by a pin on one side). When all three wafers are lined up correctly, it opens the lock and allows you to open your door.

You can see how this works if you think of it as a safe: Each number represents where each part should be placed before being able to open its corresponding safe door. So if there were five numbers on your combination safe, then there would have been five different combinations of numbers (1-2-3 would have been one combination; 2-3-4 would have been another).

Lever locks

According to a company that does professional locksmith services in Markham, lever locks are the most common type of lock in use today. They’re easy to operate and inexpensive, and they’re used on many different types of doors in homes and businesses. Lever locks are also popular because they can be opened by pushing a lever up or down with your hand, which makes them accessible for people with limited mobility or those who have difficulty lifting heavy objects.

Lever locks come in two basic designs: rim cylinder and pin tumbler. The difference is how you insert your key into the lock: either through a slot at the top of the door (rim cylinder) or from underneath through a keyhole (pin tumbler).


Padlocks are used to secure gates and sheds, cabinets, lockers, bicycles, and motorcycles. If you’re looking for a more secure way to secure your belongings, then you’ll want to consider some other types of locks.

Chain locks

Chain locks are made up of a chain and lock. They’re usually used to secure a bicycle to a bike rack, but they can also be used to secure anything else you want to keep safe, like your pet or a briefcase. Chain locks aren’t very expensive, which makes them appealing to many people who don’t know how much security they need. However, chain locks are not particularly secure; if someone wants in badly enough, it’s easy enough for them to break the lock open and steal whatever you’ve locked up with it.

Disc detainer locks

Disc detainer locks are a type of lock used on sliding glass doors. These locks are similar to a cylinder lock in that they use a key to turn and open or close the door. However, instead of having one flat face designed to fit into a matching slot, these locks have multiple circular discs that turn together when you insert your key.

Disc detainer lock installation is quite easy and can be completed in less than an hour by anyone who is moderately handy with tools. There’s no need to hire anyone if you don’t want to! You will need a screwdriver and drill bit (to make holes in your door frame), but otherwise, there won’t be any fancy tools involved—just basic hand tools like pliers and wrenches/socket sets which should already be available from around your home or garage!

The disc-detainer lock does not require any special skills for opening either; even children should be able to understand how this type works after reading through this guide once or twice (a few times more would not hurt).


If you’re looking for a lock to keep your home or business secure, there are plenty of options available. When choosing the best lock for your needs, it’s important to consider factors such as security level and budget as well as other considerations like size and weight.
