Common Lock Types Used in Homes

December 14, 2018


Humans have been locking up our homes for about as long as we have been building them. In today’s world, sophisticated burglars make it necessary to continuously ramp up home security, but basic door locks remain the cornerstone for safeguarding our homes. Yet not all locks are right for all purposes. Here is a guide to some of the most common lock types used in homes.

Arguably one of the most common lock types of all, deadbolts are in widespread use in both homes and businesses. Deadbolts are among the most secure types of lock, and are typically used on exterior doors. However, not all deadbolts are the same. They are available in single and double cylinder styles, and are graded according to the amount of force they can withstand. Some even have additional safety features built in. If you choose deadbolts, be sure to select high-quality versions.

Door Knob Locks

Door knob locks cannot withstand a great deal of force, so they are rarely the only line of defense on an exterior door. However, they work well on interior doors, and as a secondary layer of protection on exterior doors. Burglars like to gain access quickly, so a door with both a door knob lock and a deadbolt could slow them down just enough that they decide to move on.

Cylindrical Lever Locks

Have you ever seen a door handle that was long and thin, with a lock below? That is a cylindrical lever lock. This style of lock works similarly to a door knob lock, so it should not be used as the only lock on an exterior door. That said, if you like the aesthetics, there is no reason not to use this type of hardware inside your home.

Mortise Locks

Mortise locks look like cylindrical lever locks, but are considered as secure as deadbolts. They are most often found in older homes, apartment complexes, and commercial properties, but they are available to individual homeowners as well. Mortise locks are extremely strong and difficult to bypass.

Smart Locks

Smart locks have become exceptionally common. Many can be connected to a whole smart home system, enhancing overall security. Smart locks are also incredibly convenient, as you can provide and remove access remotely for babysitters, construction workers, and other service professionals, or even out of town guests. You never have to worry about losing your key, and you can change the passcode if you feel it has been compromised.

Yet smart locks are also vulnerable to hacking and data theft. Make sure you understand the security protocols for your particular lock, and always follow best practices to keep your personal information safe.

There are, of course, many other types of locks as well. Depending on your needs, you might have a padlock on your fence, a sliding door lock on the door to your pool, a locking filing cabinet, and numerous additional locks in your home. With so many locks to choose from, it is best to get advice from a professional locksmith to ensure that your home is fully protected.
