How To Open A Heavy Duty Padlock?

If you are a new user of heavy-duty padlocks, you need ample knowledge on how to safely open and lock a padlock.

The general method of opening a durable padlock is using its designated key. Or, if you’re using an outdoor combination lock that is locked with a PIN, you may have to enter the PIN to open it.

Now, imagine a scenario where you own a beautiful flower garden, and you use heavy duty padlocks to secure garden gates every day. But, one day, you just lost the key to the padlock. What to do then?

Well, in that case, you will need to break open the padlock. To break open a tough padlock, you can opt for one of 3 ways: using a bolt cutter to cut the padlock, using an angle grinder to cut the lock, or using a hacksaw to cut the padlock.

Either way, breaking and opening a padlock will take at least 15 to 30 minutes.

What Type Of Lock Is Hardest To Cut?

The difficulty of cutting a lock is determined by how it’s manufactured. The most durable padlocks are generally constructed from multiple layers of stainless steel, laminated with hardened iron/steel coverings.

However, high security padlocks made out of other materials such as lead and tungsten are also very reliable.

But, padlocks made out of lead and tungsten are not an economical choice because they cost a lot higher than stainless steel padlocks.

Now, other than the above-mentioned materials, modern padlocks are also manufactured with titanium and titanium-brass alloy. These also provide optimum protection against vandalism and theft.

That’s why they are perfectly suited to be used as heavy duty locks for gates, for Securing shed doors, main doors, and garden gates.

All in all, if we put all the construction materials in scale, I would like to say that titanium and alloy steel padlocks are the hardest to cut. Although these construction materials offer high-quality padlocks, they are not a highly costly choice.

Buying Guide: How To Buy The Best Padlocks?

Before buying a particular padlock, you must evaluate all of its qualities and characteristics.

More specifically, before making a purchase, you have to examine its size, shackle material, shackle size, shackle shape, the size of the keyhole, drilling resistance, lock pins, etc.

To make this process easier for you, we have broken down each aspect and given information on how to make the best decision when buying the Best Heavy duty Padlock. Here we go,

1. Size:

It’s best to buy a padlock that is small in size. That is a simple principle that you must follow while buying a padlock. Now, having a small-sized padlock doesn’t necessarily mean that it is weak in security.

If the padlock is manufactured from top-quality material, it will not compromise durability and security even if it’s small in size.

Rather, having a small-sized padlock will make your user experience much more easier and pleasing. It’s because with small size comes portability and convenience.

2. Shackle Material:

The shackle is the main component of a padlock that secures the lock to a certain entity. Now, if the shackle is not manufactured from top-quality material, the padlock will never be able to provide you security.

For instance, if your padlock has a hardened stainless steel shackle, you can expect good durability and resistance against bolt cutters.

That’s why buying a padlock that has a stainless steel shackle or titanium shackle is always a recommended choice. So, don’t forget to check the construction material of the shackle of your padlock before making the purchase.

3. Open or Closed Shackle:

Padlocks can come with both open shackles and closed shackles. In our opinion, it’s best to opt for closed shackle padlocks. Remember, vandals and thieves always attack the shackle of a padlock to open it.

So, if you have a closed/covered padlock, the criminals will have less chance of cutting the padlock with a bolt cutter or a hacksaw.

Consequently, this feature will be able to provide you with security that open shackles will not be able to.

Now, it should be noted here that the best long shackle padlocks in the market will generally be manufactured with open shackles.

So, if you have a particular need for long shackle padlocks, you’ve got no other choice but to opt for an open shackle padlock.

4. Key Size:

The key size is an important criterion that you should consider before purchasing a heavy duty padlock.

If the key is too large, you’ll have difficulty carrying it and keeping it in your pockets. But, if the key is too small, you run the risk of losing it in everyday usage.

That’s why we think the best padlocks are those that come with a combination key locking system. As these locks can be locked and unlocked without a key (with a pin or number combination), these are highly convenient to use for those people who tend to forget.

It should also be noted that the best combination locks in the market should come with a 5-digit combination option. So, make sure the lock you’re buying has a 5 digit combination locking system.

Now, if you are particularly looking for a padlock with physical keys, you should always buy a key lock box for your keys. That way, your keys are protected with an extra layer of security.

5. Shoulder Shroud:

If you’re buying a padlock for protecting any property that is situated outdoors, you better choose a shoulder-shrouded padlock for securing your properties.

Shoulder shrouded padlocks have hardened steel protection over their shackles that look like a shrouded human shoulder.

Due to this extra protection layer, we think the best padlock for outdoor sheds, farms, barns, and backyards are those that come with shrouded shoulders.

6. Anti Drill Plate :

To protect the assets with 100% security, some manufacturers provide anti-drill plates around the keyhole. This makes sure that the lock cannot be picked or drilled no matter what.

So, if you want extreme security, you should always pick those padlocks that provide anti-drill plates around their keyholes.

7. Pins:

A good-quality padlock will usually have 12 pins inside its keyholes. The pins and their combinations define if a key is suited to unlock a particular padlock or not.

Which is why, the more pins a padlock has, the better security it will be able to provide.

Therefore, we suggest that you choose a padlock that has at least 12 pins inside its keyhole. Also, make sure to check the pins’ specifications before making the purchase.

Frequently Asked Questions(FAQ)

1. Can bolt cutters cut through padlocks?

Although bolt cutters are preliminary tools for cutting locks, they are not capable of cutting all types of padlocks. For example, shoulder-shrouded padlocks have extra layers of metal lamination around the shackle and are perfectly resistant to bolt cutters.

2. Can I break padlocks with hammers?

Low-quality padlocks can be easily broken open with hammers. But, the most expensive padlocks in the current market are perfectly resistant to physical damage by hammers.

3. Which type of padlocks is suited for securing storage units/facilities?

A heavy duty lock for storage units will be equipped with a hardened steel laminated shackle. Also, the keyhole should be well protected by anti-drill resistant eliminations as well. Since storage units are frequently targeted by robbers and thieves, the padlock you’re buying should also be large in size.
