1. Desired Tools Padlock 4-Digit Combination Lock

The 4-digit combination lock from Desired Tools gives us peace of mind while we are away or at work. Made of metal, zinc, and alloy steel, the thief will have difficulty breaking in. Also, the fact that it has 10,000 unique combinations makes it ten times longer to decode than 3-digit locks.

Aside from that, maneuvering and resetting your code is so simple and straightforward. If you want to reset the combination number, directly use your current number instead of the default 0-0-0-0.

During the winter, I used it as a lock for my gate, and amazingly, it did not jam even once after I chipped the ice. There was also no sign of rust even if the temperature outside was minus-zero. Its weatherproof feature makes it ideal as a combination lock for gate.

I also love the lock because it comes in distinct colors like green, red, or blue. Unlike other hard-to-find locks, this one quickly catches the eye, even at night. I usually misplace some of my locks because they camouflage with my other belongings. But, thanks to its bright color, I quickly find it all the time.

Although the numbers are easy to read, the black raised arrow indicating where to align the numbers is a bit too small. So, I have difficulty seeing it during the night. Neon color or white color will make it more noticeable in the dark.
  • Difficult to break in since its construction of alloy steel, metal, and zinc
  • Offers 10,000 combinations making it difficult to decode
  • Maneuvers and resets easily
  • Weatherproof feature makes it useful for outdoor use

2. Master Lock 178D Combination Padlock

With its hardened steel shackle, the Master Lock 178D Combination Padlock is extra cut resistant. Any attempts from burglars to cut the lock will only end up in frustration.

In addition to that, the solid body makes it perfect as a school locker lock, gym lock, and gate lock. I tried measuring this padlock buid, and I found out that its body is 2 inches wide.

The package comes with a combination reset key. If you want to change the combination, insert the key. There’s no other way to reset the combination other than the reset key, so I suggest that you keep it in a safe place.

Designed for any weather, the combination lock with key is also reliable during scorching heat and zero-temperature winter. Surprisingly, it does not easily rust and corrode. Therefore, it is reliable for outdoor use. As for me, I use the lock as a chain lock for my bike.

The only problem I had was its manual. The instructions are so unclear that I had to look online regarding the set combination. The manual instructed to place the combination to L-O-C-K, which is quite confusing since the combination is in numbers and not in letters. I found out online that the default number is 0-0-0-0.
  • Includes an extra cut resistance feature with its hardened steel shackle
  • Perfect as a school locker lock, gym lock, and gate lock
  • Comes in combination and key lock
  • Does not easily rust and corrode due to its weatherproof feature

3. SureLock TSA Compatible Travel Luggage Lock

A perfect travel buddy that ensures security, SureLock’s TSA Compatible Travel Luggage Lock is a must-have. The harsh handling of luggage won’t bother you because of the ultra-tough alloy body of the lock.

This is the best combination lock I ever tried. I’ve been using it for almost three years, and there still is no sign of rusting or corrosion. What also prevents it from freezing up and hardening is its internal lock mechanism made of stainless steel.

I also loved its pop-up inspection indicator. Whenever the TSA inspects your luggage, expect that a button will pop up at the top of the cable lock. The purpose of the indicator is to remind you to check your luggage while you are in the airport to make sure that nothing is missing.

Also, if you are someone like me who has trouble with eye vision, the luggage lock is a great help. The dials are so easy to read since the numerals are in white while the background is black. You don’t need to waste your time looking for your eyeglasses.

One thing, though. I have a hard time closing the lock. It requires a lot of pressure and a firm pinch of the cable. It was a struggle, especially if your hands are wet and slippery. So for a piece of advice, dry your hands first before closing the lock.
  • Comes with an ultra-tough alloy body that can handle harsh handling
  • Includes an internal lock mechanism that prevents the lock from hardening
  • Comprises of a pop-up inspection indicator
  • Dials are easy to read

4. Puroma 2-Pack Combination Lock

Also, the side window design makes setting the combination an easy task. Unlike other locks that you need to use your two hands to enter the code; this one is different. You can enter the code with one hand only.

Concerning your locker’s security, a four-digit combination is one of its features. That means it offers 10,000 combinations. Thus, we are guaranteed high security for our houses that burglars can never break-in.

Amazingly, the package comes with two packs of 4-digit combination locks for lockers. They are made of zinc alloy, and they are black- a perfect gift for a friend or loved ones. I’ve given the freebies as a gift to my friends.

However, the downside I experienced with this code is that you can’t re-lock the lock if your numbers aren’t set. The combination to open the lock is the same as the numbers to close the lock. Unless you scramble the lock, your code can be seen by others.
  • Lightweight and easy to carry around
  • Comes in a side window design that makes it easy to set the combination
  • Offers 10,000 combinations
  • Includes two packs of 4-digit combination locks as freebies

The Master Lock 1535DWD Locker Lock comes up with cool combination locks for lockers. Instead of numbers, the combination is in letters for easy recall. You will save yourself from standing awkwardly in front of your locker while remembering the combination. Furthermore, the dials are also not interchangeable.

Moreover, it has enhanced security against shimming. By the way, shimming is the opening of a lock by using a foreign object. In this case, the lock is designed to protect the latch assembly from shim tools, preventing the thief from opening it.

Using a coin at the bottom of the lock, you can easily reset the combination. The grip points also provide accurate dialing. In addition to that, the four-letter combination in the vertical dial offers thousands of possible word combinations.

One of the features I love about the locker’s combination locks is their availability in assorted colors. There are blue, light blue, black and pink. When it was delivered to my front door, I was thrilled after opening the package because the lock was in pink color. The color and the design were perfect as a combination lock for locker.

Unfortunately, the lock is not suitable for outdoor use. I would love to have it in my gate and my garden because of its cute colors and design. However, it is better if it would have been waterproof.
  • Comes with a four-letter combination for easy recall
  • Enhances security against shimming
  • Provides accurate dialing with its grip points
  • Available in cute colors and design: blue, light blue, black, and pink
  • Not suitable for outdoor use
Anyone like me, who is tired of a plain-looking lock, would recommend this locker’s lock. The features also offer high security against thieves. However, it is not suitable for any outdoor use due to the absence of weatherproof quality.

Aside from that, the programmable combination lock includes big numbers and a unique side window and design. So senior citizens won’t have a hard time reading and realigning the numbers.

Also, the lock is reliable for outdoor use. Designed with an anti-rust treatment and waterproof feature, it can stand even in the harshest weather in countries like the UK. You can use it for your backyard gate, outdoor fence gate, sheds, and garage doors.

The only concern I have is that it is not a one-hand lock-and-go. You have to press the shackle and hold it down while setting the dial to erase the code. If both of your hands are full, then you cannot lock it with one hand.
  • Sets the personal combination easily
  • Comes in a sturdy, zinc alloy body
  • Offers thousands of combinations, making it hard to crack
  • Designed with an anti-rust treatment and waterproof feature
  • Cannot lock it with one hand only
The security features make it trustworthy against burglars because of its zinc alloy body and thousands of combinations.

7. Disecu 4-Digit Combination Lock

Compared to the short shackles, Disecu 4-digit combination lock comes in a high shackle to provide more uses. The length of the shackle is 2.5 inches. Thus, it is a perfect fit for luggage, school locker, gym locker, fence, gate, and storage.

Regarding its durability, the lock is made of high-strength, hardened steel and alloy to protect it against hammering, sawing, or prying. Because of its premium material, the lock is suitable for outdoor use.

Besides that, its small volume makes it lightweight and hand-size. You can carry it without any hassle, and you can also store it wherever you want. The weight of the lock is only 0.5 ounce with a diameter of ¼ inch.

You can also set your combination locks by setting the default code then pulling up the shackle. Then rotate it to the code setting gap and push the shackle down. Keep the tiny pin inside the gap while rotating the shackle to the code line. After that, scroll the dials to set your combination, then turn the shackle back to the setting notch until it pops up.

A piece of advice, don’t follow the instructions at the back of the packaging. Instead, read the user manual. I messed up one of the locks after resetting the code by referring to the instructions on the packaging. Good thing, though, after calling the customer service, they sent replacement locks.
  • Comes in high shackle ideal for luggage, school locker, gym locker, and gate
  • Consists of hardened steel and alloy as protection against hammering and sawing

If not for the plastic combination keys, the lock would be perfect. However, I prefer it to be in metal keys since that would make it more sturdy. I don’t know how long the combo keys will last, but as of now, they are working well.

The long shackle made of steel also protects the lock against cutting and sawing. The diameter of the shackle is 5 mm, while its length is 17 mm. Buyers should note that it is smaller than other combination locks since it is for indoor use only.

Aside from that, the bright metallic color of the locks simplifies locker identification. It is available in blue, purple and red. The small combo locks provide convenience, especially when setting the codes.

One downside is that it is too small as a lock for bigger storage. Therefore, the use of the lock is limited only to lockers, bags, and backpacks. If you need to lock garages, houses, and gates, it is advisable to buy larger master locks.
