  • Bolt Strength: Homeowners will want high security locks with hardened steel bolts that can withstand attacks. These bolts will need to offer effective resistance against sledgehammers, kicks, cutting, shoulder strikes, and much more.

Top 8 High Security Door Lock Reviews

1. Mul-T-Lock ‎008J-MD1-D High Security Lock

8 Best High Security Door Locks for More Safe and Secure (3)

One of the most secure deadbolt locks would be Mul-T-Lock’s ‎008J-MD1-D Cronus High Security Deadbolt Lock. Its durable, stainless steel construction has proven more than once to stand up to a would-be intruder.

For instance, this model comes with a steel hardened pin and steel core rosette. Both these aspects help ensure the lock can withstand drilling and picking with ease. I even had a locksmith friend try to bypass it without any success.

The product’s grade 2 ANSI rating only further confirms its impressive durability. It should have no issues protecting homes, commercial properties, or other means. Due to this, thieves aren’t going to be too fond of seeing this lock protecting their targets.

Another crucial aspect was this lock’s relatively wide adjustment range. It can fit any door between 1 ⅜” and 1 ¾” thick, covering many applications. Honestly, it would work on most doors within my home without much issue.

This lock comes with three included keys for convenience purposes, as well. It’ll be of help to a person like myself who’s constantly losing things from their forgetfulness. Plus, the lock comes with a duplicate card to make more keys if the need arises.

I was a little surprised by the lackluster installation instructions. Honestly, these directions were very basic and didn’t explain each step too well. I didn’t have to rely on them, though, but people without experience might become frustrated.


  • Durable stainless steel construction
  • Steel hardened pin and steel core rosette withstand picking and drilling
  • ANSI grade-2 security rating
  • Fits any door between 1 ⅜” and 1 ¾” thick
  • Three keys and a duplicate card included


  • Lackluster instructions

As I mentioned, the instructions didn’t impact my experience with this lock. But it’s still an issue to consider for anyone considering this high security option.

2. Medeco 11TR50319 Maxum Residential Lock

8 Best High Security Door Locks for More Safe and Secure (4)

Medeco’s 11TR50319 Maxum Residential Deadbolt Lock offers a level of durability most other options can’t match. Its metal construction with a triple-locking security cylinder is more than enough to keep most thieves from intruding.

As a result, it’s no surprise that this model comes with an ANSI grade 1 security rating. This aspect confirms that this lock is among the most secure options available. It was rather impressive to witness it withstand my bypassing attempts with ease.

The lock isn’t overly difficult to use, either. It has a key locking mechanism on the outside, and a thumb turn on its inside. Therefore, I had no trouble getting privacy whenever I required it with this particular deadbolt lock.

Medeco did a solid job with this product’s versatility, as well. It shouldn’t have any trouble fitting any doors between 1 ¾” and 2″ thick based on customer reviews. I certainly didn’t have any issues placing it onto my front door and feel much safer with it.

Lastly, the product’s design has an aesthetic that can fit into most homes. Its satin nickel finish meshed perfectly into my door’s decor. If I’m honest, this lock gave my door a much-needed upgrade when it came to appearance.

It was a little disappointing to see some customers mention packaging issues, though. These incidents seemed to consist of certain pieces getting damaged during transit. Luckily, I wasn’t one of these buyers, and everything arrived in perfect shape.


  • Durable metal construction with triple-locking cylinder
  • ANSI grade 1 rating for safety
  • Easy-to-use thumb turn and key locking mechanism
  • Suits any door between 1 ¾” and 2″ thick
  • Meshable, satin nickel finish

Honestly, I wouldn’t worry much about the packaging issues. These incidents weren’t overly frequent as most people were more than happy with this option. After all, it’s one of the most secure residential deadbolt locks available.

3. Mul-T-Lock ‎206X-MD1 High Security Deadbolt

8 Best High Security Door Locks for More Safe and Secure (5)

The Mul-T-Lock ‎206X-MD1 Interactive+Cronus High Security Deadbolt provides users with two high security deadbolt locks rather than one. Therefore, it allowed me to secure both my entry and shed doors without making two purchases.

I was also pleased with its heavy-duty key cylinder that has solid resistance qualities. It should have no difficulty stopping drilling, bump keys, and picking attempts. I haven’t had anyone test them yet, but several customers noted these locks successfully stopped intruders.

Each deadbolt lock comes with two keys (4 total) and one key duplication card, as well. It offers a lot more key control as no one can’t duplicate these keys without presenting the card. Due to this, I feel a lot more confident in how protected my valuables are behind these locks.

It’s essential to note that the keys’ construction felt durable and reliable. I doubt anyone will have issues with these snapping or wearing down over time. Mul-T-Lock clearly took their time and ensured these components were ready for regular usage.

Other notable features include fitting any door between 1 ⅜ and 1 ¾” thick, an ANSI grade 2 security rating, and several available finish types. It ends up being a solid option that provides me with complete confidence in its security.

Some customers did mention the included screws didn’t fit right during the installation. I found myself having similar issues, making me use other ones inside my toolbox. It’s not a massive concern, but it still could be frustrating in certain situations.


  • 2-pack for multiple applications
  • Heavy-duty key cylinder with resistance qualities
  • Includes four durable keys and a duplication card
  • Suitable for any door between 1 ⅜ and 1 ¾” thick,
  • ANSI grade-2 security level
  • Several finish types for various situations


  • Subpar included screws

It would’ve been nice for Kwikset to pay more attention to the included screws. But it doesn’t stop this product from being a worthwhile high security lock option.

4. Kwikset Juno ‎991 J 15 SMT CP Door Knob

8 Best High Security Door Locks for More Safe and Secure (6)

High security door locks with style aren’t too common. But Kwikset’s Juno ‎991 J 15 SMT CP Door Knob and Deadbolt certainly fits the bill with its satin nickel finish. It’ll make any door look much more appealing when it’s installed properly.

But this sense of style wouldn’t matter much without impressive protection features. Thankfully, this door knob/deadbolt combo has various ways of making sure my home stays safe. A solid example would be its usage of SmartKey re-key technology.

This attribute allows users to re-key their locks in three simple steps. I didn’t even have an issue doing it, which is a borderline miracle given my capabilities. Due to this, I never have to worry about loaned or lost keys as I can do the re-keying process.

I should also point out this product’s single cylinder deadbolt. Honestly, the security offered by this aspect is hard to match with its ANSI grade 1 rating. It gives me complete faith in this option’s ability to keep intruders from entering my home.

The lock’s locking sidebar with its BumpGuard protection is another highlight trait. It’ll only provide additional security for anyone who installs this particular option. Plus, each hardware piece is protected by Microban’s antibacterial protection for cleaner surfaces.

I did have one issue with this option, though. Both door knobs aren’t sized the same, which feels a little awkward from a user perspective. It doesn’t affect their performance, but I’d be lying if I didn’t wish Kwikset took it into account before selling this option.


  • Stylish satin nickel finish
  • Easy 3-step re-keying process
  • Grade 1 single cylinder deadbolt
  • Locking sidebar with BumpGuard protection
  • Equipped with Microban antibacterial protection for cleaner surfaces


  • Door knobs aren’t the same size

Once I got used to the door knobs, I didn’t have much to complain about with this choice. It’s a solid combo high security lock that most thieves should have trouble bypassing.

5. Master Lock M736XKAD Heavy-Duty Steel Padlock

8 Best High Security Door Locks for More Safe and Secure (7)

Intruders aren’t going to like seeing Master Lock’s M736XKAD Heavy-Duty Steel Padlock protecting their targets. For instance, this model has a five-pin locking cylinder that offers outstanding pick resistance.

The padlock’s hidden shackle design is another aspect capable of frustrating thieves. It stops easy access to the shackle for cutting attempts using bolt cutters. I tried several times to get a solid cutting position and was widely unsuccessful.

Users should consider this lock’s versatility, as well. It might not suit front door usage, but I found this option valuable on sliding or shed doors. Moreover, it can work indoors or outdoors for more convenience. It’s even shown to be helpful in protecting moving trucks and vans.

This option also has a key retaining safeguard. It stops me from leaving the device unlocked as an extra precaution. I’ve only had this lock for a couple of weeks, and it has already saved me numerous times with this feature.

One more benefit worth mentioning would be its zinc-plated steel construction. It’s another reason for the impressive strength it provides and protects against corrosion resistance. Buyers can expect this padlock to last more than a couple of years with this design.

Installing this padlock will probably require a trip to the hardware store, though. Master lock didn’t include the bolts or nuts needed to complete this process. It seems like a slight overstep as I would much prefer everything came in a single package.


  • 5-pin locking cylinder
  • Hidden shackle design prevents bolt cutter attacks
  • Suitable for various applications (outdoors or indoors)
  • Equipped with a key retaining safeguard
  • Corrosion-resistant zinc-plated steel construction


  • Bolts or nuts not included

But I can’t argue with the results provided by this padlock. After the installation, it functioned well as a high security device that offered me peace of mind.

6. Kwikset 98015SMTCP Single-Cylinder Deadbolt

8 Best High Security Door Locks for More Safe and Secure (8)

Kwikset’s 98015SMTCP Single-Cylinder Deadbolt is a bit more traditional than other options on this list. But this classic design doesn’t stop it from providing solid high security door lock defender security.

After all, it comes with a solid single-cylinder deadbolt construction built for exterior usage. It should withstand most intruder attacks from picking to bump keys without much effort. The using process was straightforward, as well.

It features an exterior lock with key access and an interior thumb turn. I had no issues locking or unlocking this model with both mechanisms as there wasn’t any sticking. I should mention that the thumb turn was comfortable to use, too, which isn’t always the case.

This lock also uses SmartKey technology to ensure re-keying is a simple 3-step process. It eliminates any worrying about lost keys or loaned keys. I have many guests coming in/out of my home, so this attribute is a godsend for me.

Moreover, this lock comes with an adjustable latch to fit on all standard doors. I can’t envision an exterior door where this model wouldn’t become a valuable security device. Lastly, Kwikset was nice enough to include a lifetime finish and mechanical warranties.

But even with these great features, it does have one notable downside. Some customers pointed to this model being somewhat tricky to install. I found myself struggling with it compared to other high security deadbolt locks.


  • Robust, single-cylinder deadbolt construction
  • Comfortable and smooth locking/unlocking mechanisms
  • Simple re-keying process with SmartKey technology
  • Equipped with an adjustable latch to fit all standard doors
  • Lifetime finish and mechanical warranties


  • Installation process can be tricky for some

In the end, hiring an installer might be the right move. But I did eventually get it done myself and found the security provided encouraging. So the initial hassle ended up being not a huge deal.

7. Hugolog Electronic Deadbolt Lock

8 Best High Security Door Locks for More Safe and Secure (9)

One of our more unique choices would be Hugolog’s Electronic Deadbolt Lock. It’s an electronic option that uses a back-lit keypad rather than relying solely on keys. Due to this, it offers a little more convenience than most high security deadbolt door locks.

The keypad itself has some intriguing aspects worth noting, as well. I found myself liking its incorrect code feature, which locks the device after ten wrong codes. It’ll prevent intruders from simply guessing random combos outside my home.

I was also happy with this product’s aluminum alloy construction. It has proven to provide valuable protection against smashing and collisions. I don’t think anyone will get through this electronic lock without a key or the proper code.

Users will be thrilled to see this product’s waterproof. It won’t have any issues working outside for daily usage like any other high security front door locks. In fact, I’ve had this electronic lock set up on one of my exterior doors for weeks without any problems.

The installation couldn’t be any easier for this lock, either. It only required a screwdriver and about 5 or 10 minutes. Most security locks for doors demand a lot more effort than what I put into this installation.

I was surprised by this electronic lock not having remote access, though. It’s often a staple of these lock types and offers a lot more convenience for the user. But this issue is more a preference problem than anything serious.

  • Keyless entry via back-lit keypad
  • Adequate protection against code guessing
  • Aluminum alloy construction with smashing/collision resistance
  • Suitable for outdoor usage (waterproof)
  • Installation only requires a screwdriver


  • No remote access

All in all, it’s a decent option to work for electronic high security deadbolt residential usage. It has had no issues keeping my home secure without me needing a key. It’s a great scenario for a forgetful person like myself.

8. Medeco Maxum 11-0102-605 Double Cylinder Deadbolt

8 Best High Security Door Locks for More Safe and Secure (10)

Our final option, Medeco’s Maxum 11-0102-605 Double Cylinder Deadbolt, ends this list with a sizable bang. It has several security features that make it a contender for being the strongest deadbolt lock available.

For instance, its grade-1 double cylinder construction is a difficult aspect to overlook. It should offer solid security to almost any exterior door. I found myself placing it on my entry door, giving me peace of mind when traveling or sleeping.

Its ability to resist picking was another appealing aspect. I had my locksmith friend come over to my home with tools to try and pick this lock. He had little success with those attempts, giving me even more confidence.

Aside from the security aspects, it looks better than most high security residential locks. The beautiful brass design provides an elegance I don’t often see with these products. It livened my front door and offered a bit more than I expected.

One of the more unexpected traits was the easy installation process. I didn’t have a single problem attaching this lock to my front door. Medeco ensured the materials offered an easy install that even newbies should get done.

I was even impressed with the included keys, as they felt well-crafted and rugged. Buyers should expect both keys to hold well even with regular use.

Sadly, the various security features do come with an increased cost. This double cylinder deadbolt is easily among the most costly options on our list. It’s worth thinking about when making a final decision.


  • Durable, grade-1 double cylinder construction
  • Tough build for exterior doors
  • Proven pick-resistance for security
  • Elegant brass design to blend with house decor
  • Easy installation process for first-time users
  • Well-crafted keys (2 per lock)


  • A higher-priced option

But security equipment is one of the areas where I’m okay with spending a little extra. Plus, this lock does earn a place among the top-rated high security locks.

What to Look for When Buying High Security Door Locks

8 Best High Security Door Locks for More Safe and Secure (11)

Buying the most secure door locks or the most trustedhigh security deadbolt isn’t a simple, one-step process. There are several layers of information to know before choosing the perfect options. But this section’s discussions should cover everything a person might need when finding suitable locks.

Lock Cylinder Complexity

Each buyer needs to consider a lock’s cylinder complexity. After all, you’ll want to try and figure out how difficult bypassing it would be for a criminal. A more challenging cylinder will make it burdensome for them to use a bump key, pick it open, and impression your lock.

But it’s also important to note that all locks are pickable. However, homeowners will want to make it as tricky as possible with a more complex locking cylinder. It’s a simple way of ensuring not everyone can get through with ease.

One way of finding more complex locking cylinders would be reading customer reviews. These resources will provide some insight into the effectiveness of these cylinders. In addition, they’ll help buyers decide whether buying each lock is worth it.

Construction Quality

A lock’s reliability will depend on the amount of metal used within its construction. You can often tell the metal content of locks by holding them within your hand. In any case, a heavy-duty lock will not use plastic parts or wide gaps to reduce cost.

These locks will consist of heavy and robust metal that doesn’t sacrifice security. As a result, I recommend only looking at locks that advertise using heavy-duty metal. Looking for options with a grade 1 or grade 2 ANSI rating is another way of determining its quality.

Bolt Strength

Homeowners will need to consider bolt strength when choosing high security locks for homes, as well. You’ll want a deadbolt capable of withstanding as much force as possible. The most secure residential deadbolt will have hardened steel bolts that can withstand thieves’ attacks.

These attacks could include battering rams, sledgehammers, kicks, shoulder strikes, and much more. But if these locks don’t have these steel bolts, these situations would snap or bend the bolt and cause a failure.

It’s also essential to note door locks with steel bolts will be resistant against cutting attacks. So thieves won’t be able to use a reciprocating saw or hacksaw to damage it. It might be a less common bypassing technique, but it’s still worth protecting against.

Drill Protection

Many thieves learn how to drill locks open because it’s a quick, effective method. Moreover, most locks don’t provide sufficient protection against drilling. But high security door locks with anti-drill precautions should prevent these thieves from bypassing your lock.

Furthermore, there are two primary points to protect locks from drills: the shear line and set screws. Both these areas are capable of being covered by hardened steel ball-bearings. You’ll also come across anti-drill plates that rotate to prevent drilling of the shear line. Make sure your chosen locks offer this type of protection.

Patented Keyways

Homeowners won’t want anyone with limited property access to copy a key without your knowledge. Due to this, a high security door lock with patented keyways is a must. This attribute will ensure access to key blanks is a lot more restricted.

But you’ll also still need to know the right way of hiding your spare keys. Otherwise, it becomes more likely that you’ll lose control of the keys. Patented keyways are just a precaution against easy key copping, not the entire solution.


High security door locks will vary greatly when it comes to price. Each buyer will need to construct based on their desired wants and needs before making a final decision. This resource can relieve a lot of stress when used correctly.

But the building of this budget has to remain realistic or it won’t be useful. For instance, buyers looking for electronic heavy duty front door locks will need higher ranges. Accounting for these little details is the only way a budget can help limit your options.

Ease of Installation

Any door locks for home security shouldn’t come with a complicated installation. Buyers should look to purchase options with simple, effortless setups that cause no stress. Otherwise, you’ll end up shelling out unnecessary money for a professional install.

You’re much better off buying a high security lock that doesn’t need a professional install. It’ll keep things much more manageable for a cost perspective and prevent an additional hassle. An easy way to determine the ease of this process would be looking at each option’s manual.

Most high security lock brands will provide the directions right within the product descriptions. Reading these instructions can help determine whether you feel comfortable doing it. Other customer’s experiences will help with this determination, as well.

Keyed or Keyless Access

High security locks aren’t always going to only have keyed access. Some advanced options offer keyless and electronic constructions to offer a bit more control. These devices are just as effective as keyed choices but offer some innovative aspects.

For instance, electronic locks will likely come with a well-lite keypad. These products will provide keyless access via a preferred code. It effectively removes the need to think about keys and whether you’ve misplaced them.

But these electronic door locks will usually cost a bit more than keyed security locks. You’ll need to weigh whether the beneficial aspects are worth paying extra. It’ll come down to preference as both options can provide excellent security.

Are High Security Locks Worth It

8 Best High Security Door Locks for More Safe and Secure (12)

High security locks are more than worth it when used in the right situations. For example, people who are in high crime areas could benefit greatly from these devices. Office buildings and commercial properties where valued items are held would be another suitable setting.

One more thing to consider would be choosing options with warranties. These policies could help lessen the risk of paying extra for these more secure locks. Honestly, I’m always going to prefer locks with these policies because I end up breaking everything.

What Type of Door Lock is Most Secure

In many cases, deadbolts are often considered the most secure lock type. This security comes from them not being able to move quickly from a locked to unlock position. As a result, thieves have a hard time getting through them without heavy-duty equipment.

Is High Security Door Locks Drill Proof

High security locks are usually made from hardened steel ball-bearings and anti-drill plates. These components can protect the drill from entering your lock or prevent the drill from being effective. Due to this, they’re as close to drill proof as locks can get.

I’d also recommend looking at each model’s strike plate locks reviews. These resources could provide a better idea about whether the lock functions well against drilling. YouTube videos are another beneficial source to help determine these drilling resistance.


Our article should’ve offered an insight into the best high security door locks for your needs. From here, it becomes an exercise of using these resources to streamline your search. They should make the entire process much more manageable.

But if there’s still a remaining question or two, please let me know in our comment section. I’ll make sure to answer each post as soon as possible. Thanks for reading!
