#1: Overall Best Gym Lock - Desired Tools Padlock Review

This combination-dial lock has a very unique design which makes it nearly impossible to crack it. The way thieves crack combination locks traditionally is by rotating the dial until they hear a click and then doing this repeatedly. With this lock, however, every digit is on a separate dial so you can’t really crack it using that traditional technique.

Apart from that, its body is made from sturdy metal with a hardened steel shackle.

It also comes with a 30-day money-back guarantee if you’re dissatisfied with it.

This weatherproof, durable gym lock from Master Lock provides incredible security. The hardened steel shackle on it is 8 mm in diameter and 1 inch long and it is fairly resistant to cutting and sawing attacks. The thief can definitely still cut through using a tool strong enough but they would need a lot of time to do so.

Best Gym Lock - Buyers’ Guide

What types of locks are most suitable to be gym locks?

The most common type of lock that is used in most gyms is the padlock. It consists of a hard metal body and typically, a hardened steel shackle that goes around your locker’s rods in order to secure it.

You're mostly limited to padlocks when it comes to gym locks. However, padlocks themselves have many different varieties. The main types of padlocks available in the market are: 

  • Key Padlock

This is the most traditional type of padlock. It comes with a key that you can use to lock and unlock it. Most manufacturers provide you with at least two keys for the lock. If you happen to lose both of them, you can still contact the manufacturer and have them replaced. Locks like these are prone to picking and bumping attacks as they have a keyway that can be exploited.

  • Combination-Dial Padlock

These types of padlocks have also been fairly common over the years. They come in many different varieties: Some come with digits on the dial while others have letters on them. These types of locks are not prone to picking or bumping attacks but there’s still a danger that someone could crack your code and break into it.

How easy is it to break into a gym lock?

It depends on the type of lock you have on your gym locker. All padlocks are prone to cutting attacks as the hardened steel shackle is always exposed. A potential thief can definitely use an angle grinder or acetylene torch to break into it. However, this would take them a lot of time and resources.

How can I make my gym lock effectively secure?

Most gym locks provide adequate security on their own. What you can do to ensure that this security is maintained is by performing regular and effective maintenance on your lock. You can do this by regularly lubricating your lock with lock lubricant. Be sure to get a high-quality lock lubricant such as WD-40 and follow its instructions exactly.

What are some things I should keep in mind when buying a gym lock?

Some things to keep in mind when going out to buy a gym lock are:

  • Build Quality

This is, by far, the most important factor. When you’re buying a gym lock, you should study its exterior and inner mechanisms to ensure that it’s made from high-quality materials. There’s no point wasting your money on a lock that’s manufactured from sub-par materials as it will start falling apart within months, if not weeks. 

You can judge the quality of the materials of the lock by inspecting the hardened steel shackle as well as the metal body exterior of the gym lock.

  • Locking Mechanism  

As we mentioned earlier, you can either have a lock-and-key, combination dial or smart lock mechanism for your lock. Before going out to buy a gym lock, you should decide on what type of locking mechanism you want for it. For example, these days everyone has smartphones but if you don’t have one, you wouldn’t want to buy a smart padlock as you’d have nothing to pair it with. 

How do I reset my combination on my gym lock?

Many different manufacturers have different ways to reset the combination. Most of them have detailed how to do this on their instruction booklets. The general way to reset the combination on your gym lock is:

  • Turn the combination dial to your current combination. The factory default for most combination locks is 0-0-0. 
  • Insert a small needle or combination reset tool (if it comes with the lock) into the small hole next to the combination dial.
  • Press the unlock button and then set the combination dial to your new combination.
  • Take your needle or combination reset tool out of the lock and lock it. That’s it!

Best Gym Lock - FAQs

Is a combination lock better than a key lock?

A combination lock is not necessarily better than a key lock but it definitely has different threats as compared to a key lock. A key lock can be broken into through lock-picking or lock-bumping. On the other hand, a combination lock can be broken into if the thief somehow finds out your code or by cutting attacks.

How can I open my combination lock if I’ve forgotten the code?

There are two ways in which you can attempt to open your combination lock if you’ve forgotten the code. The first is to attempt to crack the code and the second is to contact the manufacturer, tell them your lock’s serial number and ask them to unlock it for you. You can go for the second option if you have time on your hands but if you want to get into your lock now, you can attempt to crack it.

My key no longer turns in my gym lock. What should I do?

This is probably because the lock has become too rigid over long-time use. You can easily fix this problem by investing in a lock lubricant and lubricating your lock properly.

My key broke inside my gym lock. What should I do?

It’s actually quite simple to pull a broken key out of a gym lock. All you need is a pair of needle-nosed pliers. Grip the broken key firmly with your pliers and pull it out. This technique will work easily if your key broke initially and all of the cuts are inside the lock. If this isn’t the case and you’re having trouble pulling it out, then try rotating the key until you can’t rotate it anymore and then try pulling it out.

My combination is no longer opening my gym lock. What should I do?

This is most likely due to a defective lock or a rigid locking mechanism. You can try lubricating it with a lock lubricant but if that doesn’t work, we suggest you either contact a locksmith or the lock’s manufacturer.

How do you crack a combination lock?

Here’s how you can crack a combination lock: 
  • Apply pressure to the shackle and start turning the combination dial clockwise until you hear a click. Add 5 to that number, this number is your first number in the combination.
  • Start turning the lock counter-clockwise until you come to a point where the dial is difficult to turn. This point is your second number in the combination. 
  • After you’ve found the first two numbers, you can brute force it and try every single number on the dial until you find the third and final number.

What are the most reliable brands that are manufacturing gym locks today?

The most dependable brands that have been manufacturing gym locks for decades are: 
  • Masterlock 
  • Puroma
  • Zhege
  • Disecu
