Things to Consider Before Buying Padlock for Storage Units 

best padlocks for storage units - storage units padlocks review

There are many (but very important!) things to consider before you buy the best padlock for your storage unit.

Since this is a very broad subject, we have compiled a list of these things, so you do not have to!

#1: Determine the level of security needed

There are so many options available in the market, each varying in size, shape, and price. To get the best padlock for your storage unit, first determine the level of security you will be needing.

If you are using a fancy facility that comes with added security, you might want to skip getting a padlock altogether. However, if you are like most people, you will be juggling between getting a medium or a high-level security padlock.

If there are already some security measures being taken at the place, it would be better to get a medium-level security padlock.

#2: Should it have a shrouded or exposed shackle?

The shackle is the U-shaped portion of your lock. Now, this is the weakest part of any lock. Why do we say that? Basically, this is where a thief would cut or drill it and gain access to whatever you are trying to keep safe.

Shrouded shackle means that the shackle has a covering that protects against cutting and drilling. This is done by making it thicker and giving as little space as possible to a bolt cutter. Since traditional padlocks do not come with this covering, they are cheaper. However, this means that they are also easier to cut and, hence, lack appropriate security measures. That being said, not all exposed shackles are easy to break. There are many great locks with thick shackles that are not easy to cut.

Shrouded shackles are harder to cut or drill and, hence, more expensive. However, we would advise against opting for a cheap padlock as it can compromise your valuable items in the storage unit. The best padlocks for storage units are the ones with shrouded and thick shackles.

#3: Dimensions of your padlock

Keeping things safe is already very stressful, but it can be nerve-wracking if you finally discover the perfect padlock, only to find out later that it does not fit the place.

Most of the times you would not be able to change the dimensions of your storage unit so getting the perfect lock is very important.

To avoid such a situation, it is always advised to check the dimensions of the door and/or point where you will be installing the padlock.

#4: Choose your padlock size according to your needs

Always consider why you’re buying the padlock and where you will be using it. You wouldn't want a large padlock for a small place - it just wouldn't fit. Similarly, a small padlock for an industrial use would look odd and out of place.

#5: Regular Padlocks vs. Disc Padlocks

Regular padlocks, with or without covering over the shackles, are mostly easier to cut than a disk padlock. Because there is so little space that it is virtually impossible for bolt cutters to find space for cutting. Therefore, disc padlocks provide better security as compared to regular padlocks. Taking this into account, you will have to see if your lock actually fits the latch you are using for your unit.

These have become a standard in the industry for self-storage owing to the security and ease that comes with them. Some might even say that disc padlocks are actually the best padlocks for storage units.

#6: What about combination padlocks?

Combination locks can be great for people who forget their keys at home.

They provide adequate protection and security. However, these can easily be cut using a bolt-cutter. Moreover, there are tons of videos online that tell you how to open a combination lock in ten tries or less.

A combination padlock may discourage a lazy robber, but it is an open invitation for a skilled or even an amateur one.

We would, therefore, advise against getting these for your storage units unless absolutely necessary. It is better they stay at your gym or your kid’s school locker. Our final say? Stay clear of these.

#7: Corrosion can eat away your lock

Be careful when you are buying a lock for your storage unit in terms of corrosion resistance.

If it gets rusted easily and does not withstand changing climate, it is better to stay away from them. It will lose its core properties like strength and durability. Eventually, it would not even open if you let it rot there for too long. So look for locks that are made of materials resistant to corrosion.

Keep in mind that nothing is 100% corrosion resistant, so the most you (or the company) can do is make locks out of superior metals and alloys that do not corrode easily.

#8: Don't break your bank buying a padlock

It is needless to say that you should always keep your budget in mind. There are a number of great padlocks in the market and you wouldn’t want to overpay for something. As they say: just because it is expensive, doesn’t mean it’s the best.   

#9: Choose the best material

It is necessary that the best padlocks for storage units should be made of the best possible materials (duh!).

Steel, alloy steel, aluminum, carbides, and brass etc are some of the common materials available.

They will provide strength, hardness, longevity, resistance to corrosion and durability. However, stay away from other materials, especially plastic (obviously!).

#9: Budget

We have kept the budget as the last thing to discuss because you are already protecting something valuable. Not many people would (and should not!) compromise on the quality for the price. However, there is a wide range of padlocks in the market.

They can be as low as $5 and as high as $5000. 

The expensive ones are used in military purposes and highly sensitive industries. You would not be needing them unless you are actually storing some classified chemicals, etc.

The cheaper padlocks are low in quality, will break easily and accumulate dust. So, we suggest you stay clear of them. However, there are many reasonably priced padlocks that do not require you to rob a bank.

Additional Information Regarding Security

They can be as low as $5 and as high as $5000.

The cheaper padlocks are low in quality, will break easily and accumulate dust. So, we suggest you stay clear of them. However, there are many reasonably priced padlocks that do not require you to rob a bank.

#2: Cylinder Locks Provide Best Security But?

Cylinder locks can normally be seen on doors.

There is no doubt that cylinder locks are the most difficult to break and, hence, they provide the highest security possible. However, they are the hardest to install as well and will most likely not even fit your usual storage unit door. Even if they do, you would not be able to install them partially because they are installed by the storage facility providers.

Therefore, there are high chances that, if they do have cylinder locks, they will provide the keys themselves.

That said, NEVER accept keys if they had been in use by the previous owner. Make sure the manager provides you with a new key. The last thing you want is someone walking right into the place using a duplicate key.

#3: Storage Facility Might not Have Best Locks

Not every manager out there is a lock expert or concerned about finding the best padlocks for storage units. They might cut costs by going for cheaper locks. You would definitely want to avoid these. Although such facilities’ only security measure is not the locks, you would want to stay safe in case of a break-in.

Getting a quality lock can give you a peace of mind, at the very least.

#4: Choose the Right Facility

You can buy as many locks as you want, but at the end of the day, the facility itself is the biggest security you can have.

Choose a facility that has good lighting and proper fencing.

It should have an on-site manager so that you can always talk about your concerns and security measures are looked after more efficiently.

#5: Anti-Drill Plates - What do they do?

Anti-drill plates are very important because they will not let a drill bite into the metallic portion of your lock.

This way, it will only spin there and the lock will be safe. Plus, they are mostly made of materials that are stronger than an average drill bit - stopping and even breaking it at the end!

This is a critical feature you should be looking out for if you are searching for the best padlocks for your storage units.

#6: Lock for flawlessly operating locks

You would not want to spend several minutes in locking and unlocking. This is just not convenient or even good for any company to manufacture such locks.

Obviously, the best padlocks for storage units should work smoothly and, hence, you will be thankful that you bought such a lock at the end.

However, we do suggest that if all other demands are being met and there is only a slight issue with the working of the lock, you do not throw that option out of the window.

#7: Long shackles can be troublesome

Long shackles can be a lot of trouble? Why? Simply because they are easy prey for robbers. All they will need is a monster claw bar and you can say goodbye to your lock and stuff in the storage unit.. Since your storage unit is probably (if not definitely) going to be outdoors, you should avoid such padlocks.

So, now you would be thinking, “but then what?”. For starters, the best padlocks for storage units will have concealed shackle. This could either be a disk lock or a simpler one with raised shoulders. Either way, the shackle should not have enough space for burglar tools.  

General Security Measures

#1: Keep your key safe

It is as important to keep the key safe as it is to get a good lock. There is no point of even getting a lock if you keep losing your key.

This will eventually land you in trouble if it falls into the wrong hands. People can make duplicate keys and you may have to bear significant loses.

Therefore, we recommend that you keep the keys safe and with yourself. Only hand it over to people you really trust. Even the best of the best padlocks for storage units cannot stop this.

#2: Do not buy used locks

This one is pretty obvious, but we have seen many people make this mistake. Never buy used locks. This is just like giving someone else a key to your place and asking they rob you.

#3: Buy locks from trusted places

Now, this may not be very common, but there are instances where people were scammed by others into buying faulty locks.

This, of course, puts you at a very high risk. Therefore, always buy from a trusted hardware store. If you like to order online, use trusted sources, like Amazon, and sellers.

Always look at the reviews of other people to know what you are getting yourself into. It is better to be careful today then be sorry tomorrow.

#4: How to deal with losing a key?

Losing a key is very common. The dangerous thing about doing so is that someone might be on the lookout and replicate your key.

So, we recommend that you get locks which come with rotating pins and angle cuts. This way, your lock can only be unlocked with foreign keys.

#5: Be mindful of the hasp size

The hasp of the locker is where the shackle of the padlock goes. Since it is ideal to keep the space between the shackle and the metal body as little as possible, the hasp should be designed to accommodate it. This would discourage the burglar from using his tools.

How awful would it be to buy the best padlocks for your storage units and find out that the structures are not strong enough to support them. It means that it should not be too feeble so as to get pulled out with the padlock. You would only be losing money over something so silly.

#6: Indoor vs. Outdoor Storage units

Indoor storage units provide greater security, but also come at a more expensive price. You will be needing a lower security level padlock and you can also compromise a little on the strength and durability. You most certainly would not have to worry about rusting. With the decrease in these properties, you are looking at a much cheaper padlock.

However, if you choose to have an outdoor storage unit, the stakes are going to be higher. Not only would you need the best padlocks for your storage units, but also need it to be very resistant to corrosion and withstand weather changes. The cost for the storage will be decreased, but the price for padlock will go up. That said, we do believe that spending more here would be wiser. You will be saving yourself from bigger loses.

Final Verdict

So, here is our list of best padlocks for storage units.

They have been tested by drilling, cutting and placing outside for a long time.

All are top-quality, provide great levels of security, durable, strong, and long-lasting.

We hope that you are able to get some help from this article. As always, the last choice is going to be yours every time.
