The 5 Most Common Locks You’ll See Everywhere

Security should always be a priority. When choosing a security system for your home, you should always be aware of the kind of locks you are purchasing. Toronto locksmith understands this and thus offers you a wide range of locking devices for your safety considerations.


Padlocks are of course the most common types of locking mechanisms available. Padlocks come in a range of shapes, sizes and quality are typically removable. There are mainly two types of padlocks available – combination and keyed. Combination padlocks usually have a certain code that needs to be entered in order to be opened. Manufacturers may supply something simple like 000 and the user will change it later. Keyed locks of course require the right keyset to be entered.


Of the non-electronic locks, deadbolt is, arguably, the most secure one. The term dead refers to the fact that the lock does not have a spring system and hence cannot be opened except by moving the cylinder to the correct position using the key. Deadbolts contain either single or double cylinders. However, since deadbolts may only be opened by using the correct key, they pose safety issues as people trapped inside a building may not be able to leave in case of an emergency. This is why deadbolts are banned in many public areas.

Knob Locks

Knob Locks are typically used in residential homes and in internal doors of buildings, typically in lieu of deadbolts. However, knob locks severely lack in security. The locking mechanism is attached to the knob itself and not the door. This makes it easy for burglars to simply break the lock using a hammer or pliers and enter your home. Thus, they should never be used for entryways.

Lever Locks

Like knob locks, lever locks are also used for internal doors. Lever locks are usually more common in public buildings since they are easier to open due to the extended handle. Like the doorknob, they too suffer from security concerns. ‘Torque attacks’ where the pressure is applied on the handle to force the lock is common. To curtail this, some lever locks are ‘clutch’ levers, i.e., on applying pressure the lever simply turns doesn’t damage the lock.

Electronic Locks 

Now that we are in the era of digitization, electronic locks are becoming more and more common. They can range from simple digit passcodes to much more sophisticated mechanisms like thumb print and retinal scanners. Typically, these locks are more frequent in industries with sensitive information. However, they are slowly invading residential homes too.
