Features to Consider Before Buying a Security Padlock

best security padlock - best security padlocks review

Picking the best high security padlock can be exhausting and, quite frankly, very complex for some. So, we have compiled a list of things you should consider before you buy your padlock.

#1: What Are The Ideal Materials For High-Security Padlocks?

Strong materials like alloy steels and carbides are the best. However, solid brass and solid aluminum are good options, too.

#2: Number of Pins in the Key

By rule of thumb, the greater the number of pins, the more security you will get. Therefore, you should always check its number.

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

Now, you will need an anti-drill plate which can deflect a drill bit and keep itself from breaking. So, look for a hardened plate in your padlock. The best high security padlocks will always come with this feature.

#4: Lock Size Is Just As Necessary

It isn’t always necessary that the bigger the padlock is, the better it will be. However, if all other factors are carefully analyzed, you should opt for a bigger lock.

#5: Shrouded Shoulders vs Exposed Shoulders

Your padlock should have shrouds on the shoulder. The thicker and larger it is, the more protection you will get. If it is exposed, your lock will be much easier to break.

#6: Where Do You Need It?

Keep in mind why you are buying the padlock. You wouldn’t want to buy an expensive padlock for your school locker. However, if you own a shed or a trailer, you would be needing high levels of security.

#7: Key Padlocks vs. Combination Padlocks - Which is Better?

Combination padlocks are more convenient and key padlocks are safer. If you live in a relatively safer environment, you can opt for combination padlocks. However, we would go against suggesting them if you are in an unsafe surrounding. It is safe to say that they wouldn’t be the best high security padlocks under these conditions. The only downside to key padlock - with respect to combination padlocks - is that you would have to carry your key most times.

#8: Keep the Keys Safe

Many people tend to buy the best high security padlocks, but aren't careful about the keys. So, they fall into the wrong hands and duplicate keys are made. Therefore, we recommend that you are careful about your keys, too.

#9: Padlocks with Hasps are Important

You can also buy padlocks with hasps. These are the devices that cover padlocks such that you would have to break it to reach the padlock. However, this would cost you a little more, but it is always worth the extra security.

#10: Lever Locks vs. Cylinder Locks

Cylinder locks are much safer than level locks. This is because if you need to change the keys, you would only have to change the cylinder - not the entire lock.

We have also included our top pick along with the runner-up.
