Here are some things you should consider when choosing a padlock:

1. Determine the level of security needed

Because there are so many options on the market you should always choose smartly. Padlocks come in different shapes and sizes. Before you buy one, always determine what kind of security level you need so that later on, it doesn’t backfire.

2. Should it have a shrouded or exposed shackle?

The weakest part of any lock is the shackle which is U shaped. If you buy a shrouded shackle, you will probably get more security because they are thicker and more solid than cheaper ones. Of course, there are some exposed shackles which are not easy to brake. We think that the best padlocks for storage units are the ones that feature shrouded and thick shackles.

3. Dimensions of your padlock

It is very frustrating when you buy a padlock and find out later that it doesn’t fit where you wanted to put it. You are often not able to change the size of your storage unit so be careful when choosing a new padlock.

4. Choose your padlock size according to your needs

Always double- check when buying the padlock and where you will be using it.

5. Regular Padlocks vs. Disc Padlocks

Regular padlocks are usually easier to cut than disk padlocks. Disk padlocks generally proved better security compared to regular padlocks. This is because the is so little space that it is almost impossible for bolt cutters to find space for cutting.

6. What about combination padlocks?

Combination locks can work great for some people but we recommend that you shouldn’t buy them because they are easier to break into.

7. Corrosion can eat away your lock

You should always be careful when buying a lock for your storage in terms of corrosion resistance. Corrosion can ruin your padlock over time and then your property will be vulnerable to burglars.

8. Don’t break your bank buying a padlock

This goes without saying. You should always keep your budget in mind. The best advice is, just because a padlock is expensive, it doesn’t mean it’s the best.

9. Choose the best material

One of the most important things about a padlock is the material from which the padlock is made of. Steel, alloy steel, aluminum, carbides are some of the most common materials available. They will provide you with strength, longevity, hardness,  and resistance to corrosion.

Additional Information Regarding Security


Price of padlock can vary from $5 to $5000. The expensive ones are generally used in the military. You probably won’t need that one but you also shouldn’t buy the cheap ones because they will provide minimum security

Do cylinder locks provide the best security but?

Cylinder locks will provide you with the best security but they are also the hardest to install. One of the most important advice is NEVER accepted keys if they had been used by the previous owner.

Storage facility might not have the best locks

A lot of owners will try to cut costs by spending less on a high-quality padlock which can backfire in the future.

Choose the right facility

Padlocks are not everything when it comes to security. You should choose a facility which has good lighting and proper fencing. It should also have a on-site manager so that you can always change your security measures if it is needed.

Anti-drill plates – What do they do?

These are very important because they prevent a drill bite into the metallic portion of your lock. This is one of the most important features you should be looking for if you want the best padlock for your storage units.

General security measures

Some of the general security measures you can take in order to keep your property safe are to keep your key safe, do not buy used locks, always buy locks from trusted places, be mindful of the hasp size and always try to keep your assets indoor.
