Locks and keys have changed a lot in the last several decades. With advancements in technology touching nearly every aspect of our lives, you can bet that our locks are no exception. While electronic and modern lock types are becoming increasingly popular, a lot of homeowners still prefer to use traditional locks types to secure their homes. 

In this article, you will learn about the most common traditional lock types, as well as modern and electronic lock types that you may consider installing. Depending on your home security needs, preferences, and budget, you will want to carefully consider whether you want to stick with the locks you currently have or upgrade to a more advanced locking system. 

Traditional Lock Types

Traditional locks types generally last for about 5 to 7 years, depending on how often they are used and other factors. If you currently have one of the lock types described below, be sure to keep an eye on them if they are getting older or appear worn.

• Deadbolt Locks

Deadbolt locks are by far the most popular choice for homeowners, apartment dwellers, and other residential property owners. They are secure, durable, and affordable. The main type of deadbolt lock that you are familiar with is known as a single cylinder deadbolt lock. These locks have a turn knob on the interior side and a key slot on the exterior side. They are easy to operate and preferred by most homeowners.

The alternative type of deadbolt you may not be as familiar with is known as a double cylinder deadbolt. These deadbolts are typically reserved for doors that are made of glass or are next to windows. Instead of having a turn knob on the interior side that homeowners can use to secure their homes, there is a key slot on both sides. This makes it so that an intruder would be unable to enter your property by breaking any glass, reaching inside, and turning a knob as they might be able to with a traditional deadbolt.

• Knob Locks

Knob locks are reserved for doors within one’s home or paired with deadbolt locks on exit doors. They look just like regular doorknobs; except they have a small latch that one can use to lock to knob. You wouldn’t want to use a knob lock by itself on any entrance or exit doors since they are not considered to be very secure. They are great, however, if you want extra reinforcement on your front, side, or back doors, or you are looking to secure bathrooms, bedrooms, or office spaces within your home.

Electronic Lock Types

The latest and greatest lock types you can purchase are electronically controlled. As technology has advanced, residential locks have become more sophisticated and secure. If you plan on installing one of the lock types mentioned below, always ensure that you hire a locksmith to help you with programming and set-up.

• Keypad and Combination Devices

Keypad devices are popping up on homes everywhere. They are sometimes referred to as electronic deadbolt locks. These electronic locks use a keypad or number pad instead of a key to allow homeowners access. These models come in both stand-alone models and smart lock models. To have a stand-alone electronic lock means that the lock is not connected to any other external devices or monitoring systems.

• Smart Locks

Smart locks refer to electronic locks that connect to your smartphone, tablet, and other external devices. They operate using a keypad device or your actual smartphone as the key. These locks are great because they offer a variety of features that give homeowners full control over their home security.
When you connect these locks to your smartphone or tablet through a designation application, you can perform a variety of tasks remotely and while on-the-go. For example, homeowners can view a log of activity in and around their locks, such as when the locks were activated or when certain doors were opened. You also have the option to lock or unlock doors from the application and set timers for when your doors will unlock to accommodate babysitters, repairman, and other service workers.

• Biometric Locks

Biometric locks are the most sophisticated, secure, and expensive kind of electronic locks you can purchase. Although they are not typically used by homeowners to secure their properties, you certainly have the option to install them if you wish to. They are nearly impossible to break-in to and come with several security features.

These locks use specific and personal identifiers as alternatives to traditional keys. The two main types are fingerprint readers and iris scanners. Fingerprint readers use one’s thumb or fingerprint to allow access to a given property, while retina or iris scanners use one’s eyeball as a means of identification. 
Biometric readers are the most secure way to lock up any property, but they are also an expensive investment. Most homeowners will find that electronic, stand-alone deadbolts or smart locks will be enough to secure their homes. However, if you are interested in the most security possible, a biometric reader of some kind may be worth looking into.
