Buying Guide For Best Door Locks
By now, you already have got familiar with the best door locks available in the market. Here is our Door Lock Buying Guide to make you an expert on this so that you can advise your neighbors more confidently.
What are the different types of door locks?
Many different types of locks and various safety factors must be taken into account before buying door locks. Here are some types of door locks to keep in mind when purchasing.
Padlocks are the most well-known type of locks, they come in a variety of sizes. They are independent and portable, unlike other types of locks, since it is not permanently connected to anything. They are mainly of two types: keys and combinations.
These types of locks are mounted mainly on the outer door and have three main varieties: lockable thumb twist, single and double. Single-cylinder bolts are the most common type.
3. Knob Lock
Knob locks are usually installed in homes with outdoor doors, except for bolt locks. When buying a full adjustment of the knob lock, it is important to make sure that the hand and back device is correct.
4. Lever Handle Lock
These locks are usually used for interior doors in commercial places. Unlike the knob lock, which has a knob that needs to be grasped and rotated, the lever handle lock has a large push-down handle.
5. European Profile Cylinder
Also known as DIN cylinders, these types of locks are commonly used for locking devices in Europe and nearby countries, and are also used in North America for some dividing and sliding door locks. They come in several different varieties: single cylinder, with thumb rotation and double cylinder.
6. Wall Mounted lock
These locks are mounted on the wall. Firebox locks are usually found in large enterprises as a common type of wall-mounted locks. They are often used as emergency access and can also be used as project tanks or small safes.
7. Interchangeable Core Cylinders (IC)
These are often used in larger companies and bodies. They allow you to re-lock by changing the kernel without unlocking the lock.
8. furniture locks
These types of locks cover a variety of locks, including sliding doors, cabinets and table locks. They are of two main types: one is bolt style and the other is push-button style.
9. Mortise Lock
These locks are often found on commercial doors, as well as on apartment doors. Although the edges and mortise locks are somewhat similar, large differences in hardware are used.
10. Cam Lock
Camlocks have varieties in applications but are most often used in mailboxes, cabinets, and OEM applications with less security. They are available in a variety of lengths and can be used to interact with different types of locking mechanisms using a variety of cams or tails.
Other types of door locks include Jimmy protection bolts, rim locks, knob cylinder keys (Kik), European locks, safe locks, and switch locks, to name a few.
Choosing the type of deadbolt lock – Double or Single Cylinder?
Cylinder operated deadbolts are mainly of two types: single cylinder and double cylinder. A single-cylinder deadbolt is operated with a key from outside of the door while a double cylinder deadbolt allows operating the key from either side of the door. You can lock and unlock the single cylinder deadbolt from inside using thumb turn as it has a twist knob on the inside area.
On the other hand, as the double cylinder deadlock comes with both interior and exterior keyholes, you need to use a key from both the exterior and the interior side of the door for locking or unlocking. No thumb turn mechanism is present in the double cylinder lock.
Single-cylinder deadbolts are more popular and common than double cylinder deadbolts because of the following reasons:
- Efficiency and user-friendly
- Easy and quick installation
As a result, a single-cylinder lock is perfect for emergency exit. On the other hand, thieves can easily break the windows and reach inside for the thumb-turn mechanism. However, modern windows are sturdy, preventing to break by force.
The main reason for choosing a double cylinder lock is its enhanced security. Double cylinder deadbolts are best for doors with glass panels or adjacent windows. As there is no interior twist knob, double cylinder deadbolts prevent the possibility of entering the house by breaking the glass. An intruder cannot go inside by breaking the glass or windows because there is no thumb-turn mechanism for unlocking from inside.
However, many areas banned double cylinder lock. Its strength is also its weakness. As one cannot go inside or outside by breaking glass or windows, it is an alarming condition for emergency situations like burning. In the event of a fire, a double cylinder deadbolt may stop you from quick exist unless you can use the right key.
In amended article 5.33A, Texas Insurance Code prohibited double cylinder lock: “Double-cylinder deadbolts that lock from both sides are prohibited by City of Arlington Fire Code and considered a safety hazard”.
Fortunately, some companies come with a “captive thumb turn” key that allows you to remove the thumb turn and converts the lock from a single cylinder to a double cylinder deadbolt. However, this idea is useless in an emergency situation as you can remove the thumb-turn and make it a double cylinder deadbolt.
We recommend using single-cylinder deadbolts with ANSI Grade 1 for exterior doors. It is also suggested to avoid glass doors.
ANSI/ BHMA Grade
All deadbolt quality is not the same. There is a grading system that will tell you how strong your deadbolt is or what type of physical punishment or hammer blows it can tolerate if someone wants to go inside through destroying the deadbolt. As a result, before installing a deadbolt, you should know the grade of your deadbolts so that you can choose the right type of deadbolt for commercial or residential use.
Deadbolt grades are defined by the American National Standards Institute (ANSI). ANSI is a non-profit organization that evaluates and analyzes the development of standards for various industries including hardware products, safety glasses, and security devices.
The aim of ANSI is to ensure standardization in the builder’s hardware by analyzing the performance standards. Builders Hardware Manufacturers Association (BHMA), a trade association accredited by ANSI, also adopts these standards and grading.
A product such as a deadbolt lock with ANSI/ BHMA trademark gives you quality assurance for a certain level. These standardization grades are given through the various operational and security tests which will help you to identify the performance quality and durability of the door lock.
Though certification is not mandatory, a product with ANSI/ BHMA benchmarks will assure you the fact that the product is tested and audited. It will also make the product manufacturing procedures effective to produce a high-performance product that not only ensures durability but also gives quality.
For a specific hardware item, ANSI/BHMA standards declare four product grades (grades 1,2, 3 and 4) for hardware products where grade 1 denotes the highest levels of performance standards.
For deadbolts, ANSI/BHMA defines three separate grades where different grades represent their level of security. These grades indicate how tough and sturdy the lock when it faces physical punishment like hammer blows, and their opening and closing life-cycles. These grades also represent their life and show how long they can last.
Grade 1 is recognized as the highest quality deadbolt and used for industrial and commercial purposes. If you find a deadbolt with grade 1 specifications, you can rely on this. On the other hand, grade 3 is an average deadbolt, offering minimal security. For becoming a commercial standard, a deadbolt must need to meet ANSI Grade 1 specification.
Grade 3 Deadbolts
Grade 3 deadbolts are average deadbolt which is accepted but gives you minimal security level.
- Tested to resist 800,000 openings and closings.
- Latch bolt size is 5/8 of an inch
- Can withstand two strikes of 75 pounds of force.
Grade 2 Deadbolts
These deadbolts have the same latch bolt size and same opening and closing resistance. The only difference is it can hold up to five strikes of 75 pounds of force.
- It can withstand 800,000 openings and closings cycles.
- Latch bolt size is 5/8 of an inch.
- It can stand up to five strikes of 75 pounds of force.
Grade 1 Deadbolts
This is the highest quality and most dependable deadbolt in the market that can resist 10 strikes from 75 pounds of force. These deadbolts are mostly seen in commercial and industrial buildings rather than homes and residential areas.
- Tested 1 million opening and closing cycles
- Latch bolt size is 1 inch to the door frame.
- Can resist 10 hammer blows without giving way or can tolerate 10 strikes from 75 pounds of force.
Underwriters Laboratories (UL) is another safety science company that tested and audited products and writes a barometer for the security of different types of a keyed lock. UL 437 is considered the high-security standard locks and accepted in the security industry. Like ANSI/BHMA grades, UL 437 test also examines the resistance of various attacks such as drilling, picking, prying, and more.
However, in the United States, UL 437 is not recognized as a standard for higher security. Rather, the USA prefers ANSI/BHMA grades.
How to choose a door lock
1. Learn locking terminology
We tested the deadbolts, both conventional and intelligent, is a single-cylinder, using key operation from the outside or rotation of the thumb. High-security locks have stronger cylinders, single pin configurations, and other defenses. Industry ranking, rating 1 to 3, seems to track our rating, with rating 1 lock is the most difficult to disable. But packages do not always display such information, so you may need to check the company’s website for a lock rating.
2. Decide your Budget
High-security locks with great caliber may look expensive, and smart locks are also not cheap. But if you likely to have a theft, the deduction for the insurance of its owner may be higher than the cost of the lock.
3. Determine if you want a smart lock
The price itself may be enough to make you laugh when buying a smart lock, but before shooting it, consider its convenience. Smart locks can be very useful if you often forget to close the door, or if you need to have a contractor or cleaner when you are away from home.
Smart Lock solves these problems through the smartphone app and the optional remote lock and unlocks feature.
Just acknowledge that remote access often requires a Wi-Fi bridge, at an additional cost. (Most smart locks don’t have built-in Wi-Fi because the chips consume too much power from the AA batteries that normally power them), if you’re thinking of buying smart locks but don’t want to pay for additional WiFi access, the electronic lock can meet your needs. This type provides access to the keyboard and programs and distributes PIN codes to several guests.
4. Hook the door frame and lock.
Weak doors, especially hollow doors, can yield before the lock. No matter what kind of lock you buy, be sure to use a box made of heavy metal and fix it with screws. Another option is to install 3-inch screws on the existing impact board.
You may not want double-sided spring locks, although many cities consider them a fire hazard because you need a key to open the door from the inside, which creates the possibility of trapping people. But they can provide peace of mind if installed near the glass next door by stealing the ability to want to become a thief, break the glass and reach the turn of the unlocked thumb.
Another thing to consider while buying a deadbolt lock is the installation process. Most single cylinder deadbolts offer a one-person project where you do not need extra hands for installing the lock. If you love Do-It-Yourself (DIY), you may choose a single-cylinder while for installing the master key system or patented key control, you need to hire an expert locksmith.
Lock with strike plate:
For installing a deadbolt lock, you need to attach the “strike”, a metal plate, to your door jam. This strike plate receives the bolt and holds it firmly. For installing this strike, you need to use 3-inch screws as long screws attach the strike firmly to the door frame and jamb. While buying, it is recommended to choose a lock with a reinforced strike plate with offset screw holes so that extra-long screws and reinforced plates can protect against strong pounding.
Key is the first and foremost thing to consider while purchasing any type of security system. You cannot unlock the deadbolt without a key being inserting the right key into the cylinder. Therefore, you need to focus on the key control system and policy while choosing any types of deadbolts.
Having in mind that the best deadbolt locks are designed to protect our homes from unauthorized entry, no one will want to waste his/her money by purchasing a default product or a lock that isn’t what it is advertised to be. For this reason, I recommend that you buy any of the reviewed best front door locks since these not only include the features to enhance safety but they are also tested and approved to be safe to use.
