Choosing a lock for a storage unit is easier said than done. Since there are different types and models on the market, you might feel overwhelmed when making a buying decision. That is why we have reviewed five of the best options on the market right now. This will help to narrow down your choices. In this section, we consider some of the important things to keep in mind when making a buying choice.
How to Choose Lock for Storage Units
There are some vital factors that will guide you to make the correct buying decision. Let’s see these.
The first thing that you should consider when buying the lock is the locking mechanism of the lock. There are different types of locking mechanisms.
This is the first type of mechanism. The combination lock opens when you input the correct combination. It is commonly used for school lockers and other low-security requirements. It is cool; however, it does not offer the most security. In fact, it is rather easy to bypass.
If you are looking for a lock for your storage unit, you would likely be better off with some of the other locks we will discuss below. Or just choose from those we have reviewed above.
As the name implies, this type of padlock comes with a key. It is the most common type of padlock on the market, and it is also one of the most secure. The only downside of this padlock is that you might misplace the key. Due to the construction of the key, it is very difficult to be picked or broken open.
A consideration of the five best locks that we have reviewed in this article shows that the disc lock is our most favored option. These locks are excellent models that work to help you to firmly secure your storage locker. They are specifically made for this purpose. Therefore, lockpicks will find them very hard to break through.
There are several reasons why you should think about getting the disc lock.
Benefits of Disc Locks
Extra Thick Bolts
Disc locks come with bolts that are thicker than usual. Why is this important? Well, if your lock has a thick bolt, it will likely be really strong and will help to ensure the security of the padlock. Keep in mind that the bolts are what support the pins that lie inside the lock. The bolts are what hold the shackle tight to the bar. Without the bolt, your padlock will be rather ineffective. Normally, the bolt is hard to displace, but with the extra thick bolts of disc locks, you will enjoy even more security.
Therefore, when choosing your disc lock, check out the dimensions of the bolts. A bigger and thicker bolt will give you better performance.
Another advantage of disc locks is that the steel used in making them is more often than not, stronger than the steel used for the other types of locks. With these strong locks, you can have locks that will withstand forces of more than 500 pounds.
When choosing a disc lock based on the steel, be wary of manufacturers that claim that their locks are made of 100% stainless steel. The steel might not be as strong as claimed. Check out stuff like the added steel strength mark. The models that we have reviewed come with a premium finish, added weight, and other connotations that guarantee that the lock is durable and will give you security.
Space between latch and shackle bolt
The disc lock is differentiated from the others by the design. It comes with a very small space between the bolt-to-bolt entryway. With the smooth transition and the small space, the shackle will hold the latch much tighter than your regular lock. With the limited spatial allowance, the manufacturer can place very thick bolts in the model.
When choosing a disc padlock, we recommend that you go for a model that is named as a Discus standard lock. This designation means that the bolts are thick, rounded, and tightly packed – all of which will increase the durability and security of the lock.
When choosing the storage lock, another important factor to consider, especially if you are using padlocks or disc locks is the hasp size.
Regardless of the lock your purchase, the lock needs to be able to fit the latch of the storage unit. The hasp of the storage refers to what locks’ shackle will hold on to.
Therefore, the hasp size is of utmost importance. If the hole is too small, the shackle of the padlock would be unable to pass through it. If it is too small, there might be more allowance for a lockpick to find a way through the lock.
Apart from the size of the hasp, you should also ensure that the hasp is in such a way that the lock’s shape would fit in. If the hasp is of improper dimensions, the lock will not be secure enough.
Location of the Storage Unit
Apart from the factors that we have discussed, it is also important that you determine and keep in mind the location of the storage. Is it indoor storage? Or is it located outside and outdoors? If it is an indoor option, you might not be too concerned about the durability of the lock.
However, if it is located outside, you have to keep the effects of the elements in mind. The wind, rain, and sunlight might have a negative effect on the lock. Therefore, look for locks that are weather resistant and rust-resistant.
The material of the parts of the lock plays a big role in the efficiency of the model. It should be made of high-quality materials. That way, it would be difficult to break through the lock. It also will determine whether the lock will be able to withstand the elements, especially in the case of an outdoor storage facility.
As with other products on the market, locks come in a wide variety of prices. Some are very affordable while others are expensive.
In the case of locks, the cheaper options lack the durability and security of more expensive models. You certainly cannot expect a $5 lock to offer the same level of security as a $20 lock.
In our review, we have offered you premium and mid-range models that will give you excellent value for money.
How can I protect my storage unit?
As you might have some important valuables in the storage unit, you certainly need to secure them. Here are some ways to protect it:
- Choose a secure facility
- Have next-level security
- Access control systems
- Choose an excellent lock
- Install alarms
What is the hardest lock to cut?
Any determined thief that has the time and equipment like an angle grinder can work his way through almost any lock. However, there are some locks that are specifically designed to resist cutting. An example is the Master Lock Padlock.
Do storage units get robbed?
Although it is rare, storage units do get robbed. Research has revealed that most of the thefts from storage units come via inside jobs.
Can you cut a disc lock with bolt cutters?
The hasp of the disc padlock is hidden. Therefore, it is impossible to cut a disc lock open with a bolt cutter. It also cannot be destroyed by a hammer.
In this review of the best locks for storage units, we have thoroughly reviewed five of the best models on the market. Use the review and the buying guide to choose the best locks for your needs.
