Deadbolts

Deadbolts are usually seen on the exterior of homes and are one of the most basic ways of securing a door on the market. It is most effective when used in combination with your doors’ less-secure standard lock, such as spring-bolt lock because it acts as an additional layer of security. There are three main types of the basic deadbolts including the single cylinder, the double cylinder and the lockable thumbturn styles.

 

The Single Cylinder

A single cylinder is one of the three main variations of the basic deadbolt lock. It operates with a key on one side of the lock (the outside) and a twist knob on the inside to open and close the lock. Some like to add an extra layer of security by installing a flip guard around the thumb turn. This prevents the thumb turn from rotating so that the deadbolt cannot be handpicked or even unlocked using the key when the guard is used.

However, the single cylinder does have one main weakness. If your home can be accessed through an open window or other, the door can be opened from the inside just by using the thumbturn.

 

The Double Cylinder

The double cylinder is another main type of deadbolt.  It is considered more secure but also more hazardous in comparison to the single cylinder deadbolt. This is due to the fact that a double cylinder requires a key on both the inside and the outside of the lock. This is why they do not require any twist knob which in consequence, provides more security because it prevents unwanted unlocking.

However, this gives double cylinders 2 main disadvantages. The first is if locked, you will always need a key to open the door even from the inside.  Secondly, in case of a fire or emergency situation, double cylinders can pose an even greater problem because they are very difficult to unlock from the inside without a key. This violates fire safety regulations which have gotten them banned in some cases. Nevertheless, it is strongly recommended that a key is left inside the lock on the inside of the house to allow for safe exit in case of an emergency.

The Lockable Thumbturn Style

The lockable thumbturn is the third main type of deadbolt and is a hybrid between a single and double cylinder locks.  It offers maximum security and flexibility because it can be locked from both the inside and the outside with either a thumbturn or a key.

These deadlocks feature a key cylinder on the outside of the door and a lockable thumb turn on the inside.  Locking the thumbturn can ensure the door cannot be locked or unlocked. Therefore when people are home, the thumbturn can be left unlocked and the door will work like a normal single cylinder deadbolt. However, if the house is left empty for long periods of time, the thumbturn can be easily locked and no one on the outside or inside can operate the lock.

 

Jimmy Deadbolts

These deadbolt locks are usually seen in apartments and on double doors and are mounted on the surface. They are often preferred because of the minimal door adjustments required during installation. They are also unique because of the deadbolt interlocks with the jamb bracket, making it more resistant to being simply pulled or forced apart from the outside than standard deadbolts.

 

Knob Locks

Knob locks are a form of spring locks which are usually seen on the exterior doors of residential homes. They are usually installed in combination with a deadbolt lock for added security because they are less secure, easy to pick and the knob can be broken off with enough force. That’s why knob locks are best used as interior locks as opposed to the exterior, especially in residential settings.

 

Lever Handle Locks

Locks with lever handles are frequently used in commercial settings on interior doors because they are even less secure than knob locks. They feature a large pushdown handle that can be opened with sheer force.

There are still a countless number of other traditional styled locks to talk about. However, if you are looking for a more modernised and digitally advanced smart locking system, there are other options for you to consider.

 

Electronic Digital Locks

There are several types of electronic locks such as those that use a swipe card or a pin code. They have been used on cars and hotels for a long time but are now available for instalment in residential settings too. Indeed there will always be the threat of having your property being broken into and with electronic locks, it is now a matter of hacking rather than picking. However these locks are convenient as they don’t need to be changed if you want to rekey, rather they can be reprogrammed.

 

Smart Locks

These locks are some of the latest technologies that have recently come out. Smart locks have been designed to operate remotely using an app on your phone. They are essentially a keyless alternative which comes in various designs to choose from.
