In this post, we picked out the best high-security door locks we could find. They’re the ones that we believe have the best features at reasonable prices.

Features of High-Security Door Locks
Every type of door lock can offer different features and levels of protection. The features below are the ones that we believe every high-quality security door lock should have:
Security Bypass Resistance
In the past, even the well-known brands of door locks were easily bypassed by intruders. They often discover the weakness of a door lock and use that to bypass it. Newer iterations of older models from well-known brands have already been added to ensure that it’s not easily bypassed. When choosing a door lock, make sure that you know whether the lock has a bypass.
Picking and Drilling Resistance
Some burglars have learned how to drill locks to access your house because it is generally easier and faster with a cordless drill. Thankfully, high-end door locks are available that can withstand drilling.
They use hardened metal that will destroy drill bits and frustrate drilling attempts.
When choosing a door lock, make sure to check that the set screws and shear line are reinforced since they can be vulnerable to drilling. These areas are often covered with steel ball-bearings for added protection.
Patented Keyways to Limit Unauthorized Key Duplications
When you want someone to be able to get into your house and look after pets, etc., the typical solution is duplicate keys. But what if unscrupulous individuals can have your keys copied without your authorization?
High-quality door locks should have patented keyways to restrict access to key blanks. This is the best way to protect yourself in case someone wants to duplicate your keys to illegally gain access to your home.
Complexity of the Door Lock Cylinder
Unless you want a keypad door lock, choosing a complex cylinder door lock will deter criminals from trying to pick the lock. Remember that most locks can be picked, but investing in a more complex lock cylinder will increase the difficulty and time required.
Deadbolts made with hardened steel ensure they can’t be easily kicked, hammered, or forced open. Strong bolts are not easily snapped or bent.
A high-quality door lock has a high metal composition and feels heavy. It doesn’t have wide gaps or plastic parts, making it hard to wring off or break to bypass it. If your door lock doesn’t have these characteristics, then you’ll likely end up compromising your security.
Precision of Cuts and Assembly
One of the many qualities of a high-end door lock is that it is designed with precise cuts and grooves. That’s important because it makes it harder to insert tools to pry open the lock.
Types of Door Locks
High-security door locks come in many different types. Depending on your preferences, you can choose the one that doesn’t only promise protection but also fits your needs and budget.
Door knobs are often installed on interior doors and designed with locking mechanisms within the door handle.
Deadbolt locks are generally used for exterior doors and designed with a single or double cylinder.
Mortise locks are among the most durable and secure door locks because they are installed into the door, unlike other locks where you have to install them to the outside of the door.
Biometric locks use the owner’s fingerprint to gain access to the main door.
Unlike the mechanical door locks which are quite traditional, electronic locks use keypads or touchscreens where users can enter a security code to gain access to the door. Normally, they require batteries to work.
Smart locks are often used with a smartphone to gain entry. These locks are connected to a WiFi or Bluetooth so that the user can control it through a smartphone.
Things to Consider Before Buying A Door Lock
Before you make your final decision, consider these before choosing a high-security door lock:
High-quality door locks are generally not cheap compared to common simple door locks. But you don’t want to compromise your security over cost. Plus, these high-end door locks should be considered an investment rather than a loss. Some high-quality door locks can be overly expensive while other brands offer almost the same level of protection at a reasonable price. Make sure to choose the one that fits your needs and your budget.
Smart Lock vs. Conventional Lock
Do you like the convenience of smart locks or are you the traditional type who would prefer the conventional locks. While conventional locks are generally more robust, smart locks can offer convenience such as eliminating the need for keys if you are forgetful or if you have cleaners you want to let in when you’re away from home.
A door backset is a distance between the edge of the door to the door lock’s drilled hole. This is very important because you could have a door that has been drilled differently and your lock may not fit well. Most door backsets in the US have measurements of 2 3/8 or 2 3/4 inches. These common measurements can fit most locks available in the market.
Remember that a door lock that is not correctly fit on your door can be easily kicked or hammered.
Strengthen the Door Frame First
No matter how good your door lock is, a door frame that is weak or hollow-core doors can give way when an intruder tries to force the door open. One way to ensure that you have a strong door frame is to use a heavy-duty strike plate which you can install with the provided screws. Or you can use 3-inch screws to secure the hinges and strike plate.
ANSI Grade for Door Locks
ANSI (American Nation Standards Institute) standard for door locks is a grading system that determines the quality of a door lock based on toughness, longevity, and latch length. Depending on the applications, the door locks have three grade levels and these are:
This grade is the highest level for door locks and is often used for commercial security. A door lock with this grade can withstand 250,000 cycles, 10 door strikes using a hammer, and 360 pounds weight test. It also comes with a 1-inch latch bolt. An ANSI Grade 1 door lock is tested with 1 million opening as well as closing cycles, making it the toughest and most secure door lock.
The ANSI Grade 2 door lock is a mid-grade quality door lock ideal for residential security. This type of door lock should withstand 5 strikes at 75-pound force as well as 800,000 cycles. The Grade 2 door lock comes with a 5/8-inch latch bolt and exceeds the requirements for apartment buildings but may not be strong enough for commercial use.
The ANSI Grade 3 door lock is often used as an added security for a door. It comes with a 5/8-inch latch bolt and tested with 800,000 opening/closing cycles. This type of door lock is expected to withstand 2 strikes at 75-pound force.
