What is A Cylinder Lock?

A cylinder lock is a cylinder device that has one or more keys to open it. Cylinder locks are used on doors, sheds, garages, and even padlocks.

Cylinder locks require not only the cylinder to be locked or unlocked, but also requires a separate key (or turning mechanism) for locking and unlocking.

Why Do We Need Cylinder Locks?

There are many different types of cylinder locks available in the market today- from antique wooden cylinder locks like those found in Egyptian tombs to modern-day cylinder door sets that can be opened using magnetic cards or fingerprints, cylinder locks will always play an important role when it comes to securing your property with physical security devices such as entry door knob sets

Today’s cylinder locks are made to be more secure than cylinder locks from the past, and cylinder door sets that you commonly see today come with electronic cylinder cores that offer high levels of protection against forced entry, tampering, and bumping

The cylinder lock also serves as a secondary safeguard when paired with an entry door knob set.

Cylinder locks can be opened using keys or combinations so they provide an extra layer of security when paired with your entry doorknobs.

FAQs About Cylinder Locks

What would cause cylinder locks to be faulty?

Faulty cylinder locks can happen for a number of reasons. If you notice that your cylinder lock isn’t working properly or turning correctly, it could mean that it’s about to fail. If you have cylinder door sets installed in your home and you notice the cylinder becoming difficult to turn or opening on its own, then the cylinder needs replacement

What are some signs that cylinder locks are faulty?

  • Faulty cylinder locks will feel sticky when turned
  • The cylinder lock may not turn at all if it has come loose
  • Your entry door knobs may become difficult to open even after replacing the doorknobs with new ones, which means that the cylinder locks inside the cylinder door sets need replacement
  • Cylinder locks may also fail due to water damage, which means that you should have them replaced as soon as possible

What are cylinder lock components?

Each cylinder lock contains a cylinder core and a shell. The cylinder core is the part of the cylinder lock that’s inserted into your entry doorknob.

The cylinder core can be opened using combinations or keys depending on your preferences for security purposes.

You can open a mechanical key cylinder lock by inserting a key into it and turning either right or left until the locking mechanism releases

The shell is what holds all of these parts together. It covers each component individually to protect them from dirt, water, and other elements that could damage cylinder locks over time.

What types of cylinder lock installation are there?

There are three different types of cylinder lock installation.

The first one is a cylinder door set that can be installed into your entry doorknob. You’ll need cylinder locks if you have a cylinder door set.

Cylinder replacement services will only include the cylinder core and not the cylinder shells because each one comes with its own shell for a more secure fit.

The second type of cylinder lock installation is where a new entry doorknob with a cylindrical hole gets installed, and then you get cylinder key locks to match it instead of cylinder door sets with cylinders inside.

The third type is when two new doorknobs get installed with cylinder locks inside of them, and you don’t have cylinder door sets on the entry doors at all.

What is a double cylinder lock?

A double cylinder lock has two cylinders instead of one, which means that there are more parts required for installation.

If you choose to go with this option, make sure that your local cylinder locksmiths provide cylinder replacement services as well as cylinder rekeying options.

This is because rekeying makes it possible to match up all of the cylinder cores so that you only need one key for each set of doorknobs.

Why should I get cylinder locks instead of doorknob sets?

Cylinder lock services are a much better option to go with than knob and deadbolt sets because they allow you to match what’s happening on the inside of your entry door knobs with cylinder core technology.

The cylinder cores can be opened using combinations or keys depending on your preferences for security purposes.

This way, you’ll get more protection from weather elements such as water and extreme cold/heat that can cause cylinder locks to become faulty.

Cylinder lock services have a number of benefits over knob and deadbolt sets which you’ll be able to enjoy especially if you choose cylinder rekeying as a cylinder locksmith service.

These are just some of the many reasons why choosing cylinder lock services is better than going with other options such as knob and deadbolt sets when it comes down to how well these types of cylinder locks protect you from weather elements.

Door Lock Buying Guide - Consumer Reports

The deadbolts, electronic locks, and smart locks that enter CR’s labs get kicked, picked, and drilled into oblivion.

For the kick-in tests, CR’s test engineers built a custom jig that allows them to swing a 100-pound steel battering ram at a replaceable section of a door with the deadbolt installed. They repeat the test eight times, dropping the weight from increasing heights or until the lock fails. The models that fail—and at least half do—then go through another test round with a reinforced box strike plate installed on a new lock sample. Again and again, CR’s experts have found that this basic do-it-yourself upgrade improves security for any lock (more on that later).

For the drilling test, we evaluate how well each lock can withstand an attack from a cordless drill. And for the picking test, we assess the internal mechanisms of each lock to see how easily it can be picked.

All models, including smart locks, receive a score in each of the four break-in tests, allowing you to easily compare a lock’s strengths and weaknesses in the face of a physical assault. The only exception is with retrofit smart locks. These locks replace only the interior side of your existing deadbolt, essentially adding smarts to the lock you already use. As a result, a retrofit smart lock’s resistance to kicking, picking, and drilling is entirely dependent on the deadbolt it’s paired with.

Both types of smart locks also get additional testing. We investigate features such as smartphone alerts, remote locking and unlocking, geofencing (the ability to automatically lock or unlock the door based on your ’s location), third-party app and voice control (via Amazon Alexa, Google Home and Assistant, and Apple Home and Siri), shareable electronic keys, access logs of who comes and goes, and even tamper alarms. Our testers factor these features into our ratings under headings that include ease of remote access, convenience, and security add-ons. We also run through the wireless setup process to see how difficult it is to connect the locks to a smartphone and other smart-home devices (such as smart speakers), putting ourselves in your shoes. For details on how well each door lock performs in these tests, see the results in our door lock ratings. 

The price alone might be enough to make you scoff at buying a smart lock, but before you dismiss it, consider the convenience it delivers. A smart lock can be very helpful if you often forget to lock your door or need to let in a contractor, cleaner, or dog walker when you’re not home. They’re also a great way to know when kids get home from school.

Smart locks solve those problems by way of smartphone apps and optional remote locking and unlocking features. Just know that remote access sometimes requires some sort of WiFi bridge at an additional cost. (Many smart locks now have WiFi built-in because the technology has become more power-efficient over the years.) And if you’re considering a smart lock but don’t want to pay extra for WiFi access, an electronic lock might serve your needs. This type offers keypad access and the ability to program and distribute PINs to various guests, but it can’t talk to your smartphone.

Weak doors—in particular, hollow-core doors—may give way before the lock does. Whichever type of lock you buy, be sure to use a box strike made of heavy-duty metal and install it with the screws provided. Another option is to install 3-inch screws on your existing strike plate. Hinges should also be secured with 3-inch screws.

You might not want to spring for a double-sided lock, though. Many municipalities consider them to be a fire hazard because you need a key to unlock the door from inside, which creates the possibility of being trapped. But they can offer peace of mind if installed on a door adjacent to glass sidelites by denying a would-be burglar the ability to break the glass and reach in to unlock the thumb-turn.

Some smart locks will soon adopt a new wireless technology called UWB (which stands for ultra-wideband) that can accurately determine a device’s location within centimeters. It’s the same technology used in Apple AirTags. Smart locks can use UWB to track your ’s precise location to unlock a door as you approach it and lock it when you leave, all hands-free without you needing to take your out of your pocket or bag.

Smart locks with this technology will hit the market later in . This technology is part of yet another new industry standard called Aliro, which is being created by many of the same companies behind Matter. You will likely see Aliro branding on smart locks with hands-free unlocking in the near future.
