BUYER'S GUIDE

When buying a new door lock, there are a lot of things to consider. From the type of lock to the materials and style, if you’re looking for the best door locks on the market it helps to have some basic knowledge first.

This buyer’s guide will help you pick the perfect lock for your needs. We’ll cover different types of locks, brands, quality, styles, and costs to give you all the info you’ll need to make the best choice.

Types

Door locks can be split into two main groups; conventional locks, like those used for many years, and smart locks that offer connectivity and other smart features. Further separation can be seen within these groups too, with conventional locks splitting to standard knob locks and deadbolts.

Conventional deadbolts are the standard lock used to secure most homes. While they often don’t feature any fancy functions, they can range widely in quality and price, with some top-end models even boasting drill-proof materials. Affordable and sometimes re-keyable, conventional deadbolts significantly improve security over knob locks, as the locking cylinder sits within the door rather than the knob.

Smart locks, on the other hand, offer many features and functions that are not possible with conventional locks, all while providing the same if not better security. From keyless entry to voice control and access logs, smart locks open up a world of home security not previously available.

These smart functions are enabled when the lock connects to your existing Wi-Fi, allowing for a range of authentication methods and additional features such as remote locking and alarm integration.

Brands

If you’re looking for a new door lock, chances are you’ve come across some familiar brand names. Many of the most trusted brands in door locks have been operating for many years, and for good reason. Their products are tried and tested so you know your home is secure.

While there are many door lock manufacturers in the world today, below is a list of the most trusted:

Schlage

Founded in 1920, Schlage is one of the most popular brands of residential and commercial locks in the United States. More expensive than some other brands, Schlage locks are known for their sturdy materials and for being difficult to pick or bump.

Kwikset

In business for over 80 years, Kwikset makes a range of products from entry-level standard locks to high-end smart locks. Standard Kwikset locks are one of the cheapest on the market and also one of the easiest to pick.

Baldwin

If you’re looking for a good mid-range lock it might be worth checking out Baldwin. Not the best and not the worst, Baldwin has a long history and uses top-quality materials in its locks.

Yale

Founded in 1868, Yale is one of the oldest international brands in the lock industry. With a reputation for quality craftsmanship, Yale is considered the creator of the modern pin-tumbler lock.

Medeco

One of the most famous lock brands around, Medeco locks feature angled key cuts with elevating and rotating pin-tumblers, making them virtually unpickable. Although on the higher-end of the market, if you’re looking for the Ferrari of the lock world, don’t go past Medeco.

Quality

To help identify the quality of door locks, industry standards were established with defined benchmarks for operation and security. Each lock must pass a series of operational and security tests to be given a rating. The grading system is accredited by the American National Standards Institute (ANSI) and is referred to as an ANSI grade.

The ANSI grading system was developed by the Builders Hardware Manufacturers Association (BHMA) and ranges from 1 to 3 depending on the results of a number of operational tests. Factors such as lock longevity, toughness, and latch length also play a role in determining the grade. ANSI grades break down as follows:

Grade 1

Best. Highest security available, meets commercial building codes and available for residential use via deadbolts.

Grade 2

Better. Exceeds standard residential requirements, grade 2 locks are often mid-range and mid-priced.

Grade 3

Good. Provides minimal residential security, grade 1 locks are generally used as secondary locks.

When looking at the best door locks on the market, check the ANSI rating and ensure your lock meets your needs. Grade 1 locks are recommended for any external doors for the greatest security.

Styles

While we’ve already looked at the different types of locks, conventional and smart locks alike offer a range of different styles to choose from. With each offering its own purpose, ensure you select the right lock style for your needs.

Knob locks

Knob locks are popular residential door locks often used for internal doors or as a secondary precaution on external doors (along with a deadbolt). As the lock cylinder is stored inside the knob, these locks are not generally suitable as the primary lock on external doors.

Deadbolts

Often considered the standard lock for residential security, deadbolts have rightly earned their place at the top of the pack. Separate from the doorknob itself, deadbolts provide an additional level of security to a knob lock and can prevent someone from breaking down the door.

Lever handle locks

These handle locks work in much the same way as knob locks except the handle is a lever instead of a knob. Generally best used on internal doors, lever handle locks can improve accessibility for those less capable but provide only minimal security.

Jimmy-proof deadbolts

Deadbolts offer great security, but for ease of installation and expert security, it’s hard to go past a jimmy-proof deadbolt. Frequently found in apartments, these deadbolts are easily installed and offer great security by interlocking with the bracket which prevents it from being pulled apart.

Rim latch locks

Rim latch locks have a cylinder on one side and a surface mount latch on the other. These locks can auto-lock behind you and are a popular lock choice in many apartment buildings. Often used in conjunction with a deadbolt, rim latch locks cannot withstand a lot of force so are not considered suitable as a primary door lock.

Cost

Door lock prices are influenced by a number of factors, including the lock strength, type, materials, and ANSI rating. While it’s important to choose the best door locks for your needs, it doesn’t necessarily mean breaking the bank. When looking for external locks, for example, if your budget can’t stretch to an ANSI Grade 1 deadbolt, you can always add additional security measures to a Grade 2 lock.

The type of door lock you purchase will also directly influence its price. Are you looking for a smart lock with remote unlocking and Wi-Fi connectivity? Fantastic! Just don’t expect to get it all for under $20. With more and more technology pouring into household items to make them ‘smart,’ prices for some items may be prohibitively high.

When it comes to door locks, cost and security do go hand in hand. This is not to say that lower-end locks are worthless, but they may only be suitable for internal, not external doors. If you’re looking at the lower end of the market, consider multiple locks to increase security or employ a reinforcement lock for added peace of mind.

F.A.Q.

How to Pick a Door Lock?

Picking a door lock is a useful skill to have should you ever lock yourself out of your house. Depending on the type of lock you’re trying to get past, picking a lock can be a simple as pushing a credit card through the door jamb to release the latch.

If you’re in a pinch and need to pick a lock, read on – just note this should never be used for criminal purposes.

Collect your tools

To pick a lock you will need a pick and a tension wrench. Most people don’t have a lock pick set laying around, so find at least two bobby pins to create your tools.

Create pick and tension wrench

To make the pick, remove the plastic ends from one bobby pin and unfold it so it’s relatively flat. Place the straight end of the pin about ⅓” (or 1cm) into the lock and bend the end to form a small hook. With another bobby pin, make the tension wrench by placing the closed end about 1” (2.5cm) into the lock and bend at 90 degrees to create an L-shape.

Use the tension wrench

Place the shorter, closed end of the tension wrench into the lower end of the keyhole and apply light tension in the direction the key should turn.

Pick the lock

While holding the tension wrench in place, insert the pick into the lock and find the pins keeping the lock in place. Starting from the back, probe and push the pins in an upward direction to release the spring. Once set, the plug should rotate slightly and you can move on to the next pins. Repeat for each pin and once all are set, the plug should rotate freely as if there was a key.

This process can be difficult to master and is sometimes considered more of an art than science. If you’re locked out of your home and need to get in urgently, call a locksmith for assistance. If you have time to practice, lock picking can be a very useful skill to acquire.

How to Change Door Locks?

Changing door locks is generally easy enough for almost anyone to do. By simply unscrewing and removing the existing hardware, you can easily see how your new lock needs to be installed. If you’re needing to replace a standard knob lock follow the below instructions:

Remove the old knobs

Using a screwdriver (not a drill), unscrew the knob plate from each side of the door and remove the knobs. If your lock has an interior cover, unscrew this and pry it away from the door with a flathead screwdriver.

Disassemble lock sections

Remove the screws holding the interior and exterior lock sections together. Once removed, pull each side away from the door to release the knobs.

Remove the latch

Unscrew the faceplate and latch mechanism from the side of the door and pull out.

Install your new door lock

Once the old lock is removed, flatten out any areas on the door as necessary and install the latch. Screw the faceplate into place to hold the lock steady.

Install new lockset

Make sure the keyed section is on the outside, then install the new lockset. Slide both parts through the hole and screw into place.

Test

Once you have installed your new lock, test to make sure everything is working. Adjust as required and tighten down all screws firmly.

Removing and installing a door lock is a straightforward process. To ensure your new door lock is installed correctly, follow the instructions included with your new hardware.

How to Fix a Door Lock Cylinder?

A jammed door lock cylinder can be an annoying problem to fix. Lock cylinders jam for a variety of reasons, including overuse, incorrect installation, or blocked mechanism. Depending on the cause, you can often fix a jammed door lock quickly using one of the below methods:

Spray graphite or lubricating spray into the keyhole

This may loosen up whatever is jamming the cylinder and help improve its function.

Use a key extractor

If a key has broken off inside the lock, purchase a key extractor from a hardware store to remove the broken piece from the lock.

To loosen a rusted lock, remove it from the door and soak the mechanism in kerosene for 24 hours.

Remove the faceplate and check that everything aligns

Misaligned latches are a common cause of cylinder jams and can be easily fixed by correcting the latch alignment or cutting out more of the door or frame.

If all else fails, contact a locksmith. While the above methods can be very useful, some locks just won’t budge and may require a professional’s touch.

How to Put a Lock on a Door?

Installing a deadbolt on a door can be an easy process if you have the right tools. To do this, you will need a chisel, screwdriver, drill, drill bits, and a hole saw along with your new lock.

Using the manufacturer’s template, mark the front, back, and side of the door so you know where to drill. It’s recommended to install deadbolts are 6” (15cm) above the doorknob. Once marked, drill out the hole on the front and back of the door using a hole saw.

Change drill bits to a ⅞” (2.2cm) spade bit to drill a hole in the side of the door for the bolt. Fit the faceplate to the hole and mark where it will be installed. Using a chisel, cut away the wood so the faceplate fits flush against the door. Drill holes and secure the bolt to the door with screws.

Install the cylinder and thumb lever to the door. Start with the exterior side before fitting the interior and fasten the deadbolt in place with screws.

Mark the end of the bolt with paint or lipstick, close the door and turn the deadbolt to mark the door frame. This will give you a guide mark so you can use the spade bit to drill the deadbolt hole in the door frame. Mark where the strike plate will sit on the frame over these holes before chiseling away any excess material so the plate is flush and putting in screws.

How to Open a Door Lock?

Opening a door lock is normally as simple as inserting the key and turning. However, with smart locks on the rise, unlocking a door isn’t always that simple. Many new products feature keypads, RFID readers, or even fingerprint scanners for increased security.

To open any lock, look at the mechanism to work out how it operates. Most locks we encounter in our day-to-day lives work with a key and can be operated with ease. If you have a new smart lock and are unsure how it works, check the instruction manual for further information.

FINAL VERDICT

A good door lock can mean the difference between someone getting into your home or not. Whether you’re changing locks to a new house or trying to improve security in your existing home, the best door locks should keep your family and possessions secure and worry-free.

Whether you’re looking for a conventional or smart lock, check out the security grade of any new door lock and ensure it meets (or even exceeds) your needs. With the rise of bump keys and home break-ins, lower graded locks may not be secure enough to stop someone getting into your home.
