Evolution Locksmithing Different Types Locking Systems

Have you ever wondered how many types of locks are out there? Nowadays, there are various types of locks that tailor to any level of security that you are looking for. From traditional lock and key systems to smart locks and access control systems, there is no shortage of choices.

There is no doubt that emergency locksmiths certainly have their hands full today with so many different door locks out there! Trying to keep up with all the changes can be overwhelming.

Do you want to learn more about the different types of locks that are out there? For this article, we are going to keep our focus on the traditional lock and key type locks, so please keep on reading below to learn about seven different types of locks now!

1). Padlocks

Of course, we have to start off the list with the classic padlock. Padlocks are locks that are not permanently attached to anything. They typically have a shackle to secure an object and come in all sorts of shapes and sizes.

Combination locks are an example of a padlock that opens when the correct combination is encoded. Other padlocks such as keyed padlocks require a key to unlock. They can either be key-retaining, where keys cannot be removed while the lock is open, and non-key-retaining, where key removal is allowed while the lock is open.

However, the disadvantage is that padlocks are quite easy to get around since they can be broken by forces like hammers or bolt cutters. They can also be prone to lock picking or shimming.

2). Knob Locks

Knob locks are the primary locks for residential homes for both internal and external doors. They typically have a key cylinder on one side and a rotatable knob on the other to maneuver the locking mechanism.

Just like padlocks, however, knob locks can also be easily compromised by brute force. They can also be prone to picking and shimming.

3). Deadbolts

Deadbolts are often installed on external doors. They are unique because they cannot be rotated without a key. They can be classified into three types: single, double, or lockable thumb turn.

Single-cylinder deadbolts are common in residential homes and have two separate ways to activate the locking mechanism: a key cylinder on one side and a rotating thumb turn on the other.

Meanwhile, the double cylinder deadbolt has a key cylinder on both sides of the lock but can be a fire hazard since you need a key to unlock it from the inside. 

Finally, the lockable thumb turn has a lockable key cylinder that can let you lock the thumb turn. Similar to the single-cylinder deadbolt, lockable thumb turns have a key cylinder on one side and a thumb on the other.

4). Lever Handle Locks

More often than not, you can find lever handle locks on the inner doors of most commercial buildings. Like knob locks, they have a key cylinder on one side and then a rotatable turn knob on the other side.

Levers are very easy to open which is why they are found in commercial buildings and are preferred for the handicapped. 

They can be compromised by lock picking and brute force, but some lever hand locks have “clutch” levers that will not force pressure on the locking mechanism should brute force be applied to the locked lever.

5). Cam Locks

Cam locks are popularly used for filing cabinets, lockboxes, mailboxes, and other security appliances that have low-level security. They can come in various lengths and tailpieces, or “cams,” that need a key for it to be rotated in and out of the door slot.

6). Mortise Locks

These dual-action locks can act both as a doorknob and a deadbolt. They require more skill to be installed since they are much stronger locks in comparison to traditional locks. Though they can be prone to lock picking, they do provide significant protection.

7). Jimmy Proof Deadbolt

You will be able to find Jimmy Proof deadbolts in older apartments or double doors. They are easy to install because they are simply surface mounted to the inside of the door.

These locks consist of two interlocking vertical bolts. Once the lock is activated, these bolts will fall into a strike plate. They also have a single cylinder that makes use of a key on one side and a turnable knob on the other side. 


Surprised that there are so many types of locks? Well, the truth is that the list still goes on! The locksmith industry has evolved so heavily to help continuously elevate security that now there are biometric systems, keycards and all sorts of access control systems. 

Anyway, for most residential houses, the more traditional style of lock is all that is needed. So whether you need a simple padlock to keep your items safe or you need a dual-action lock such as the mortise lock, speak to your local locksmith about the best lock for your situation.
