What to Consider While buying a Puck Lock

How do you find the best puck lock for trailer? You can’t just make a random selection. Use these factors to guide your decision:

1). Consider Puck Lock Material

What materials did the manufacturer use? The materials determine the strength and durability of the lock. Many people flock to locks made from low-cost materials because they are inexpensive. But a cheap lock is pointless. It creates the illusion of security, but you can’t trust the lock to keep your valuables safe.

Look for locks made from stainless steel and other high-quality materials. If you have no other choice, aim for zinc. Zinc is not the best, but it is better than many cheaper alternatives.

2). Brand

The brand matters. Some companies have a reputation for making high-quality trailer locks. Others make junk. Listen to the public. What are people saying about your brand of choice?

Do they like the locks they have purchased from the company in the past? Do those locks last? What sorts of complaints have they raised? The public will not buy trailer locks from an untrustworthy brand. Where trailer locks are concerned, you should follow the masses.

3). Ease of Use

Naturally, you must pay close attention to the security considerations. For instance, how thick is the shackle? How much of the shackle is exposed? Can you pick the lock?

These questions are important. However, they are not as relevant as the ease of use. No one will use a trailer lock that is difficult to install, no matter how solid and secure it is.

Try to find a lock that balances all these factors, that is, a thick item with a solid construction that is also easy to install and use.

However, if you have self storage unit and you are searching for a storage lock to secure your storage unit, then you should buy disk padlock.

How Does A Puck Lock Work?

Padlocks are no longer the answer to life’s security problems. Some of them have thin shackles that fit tiny door hasps, but that makes them easier to cut. Large shackles are no better because they are still vulnerable to bolt cutters.

Once you understand the weaknesses plaguing the average padlock, the benefits of a puck lock become obvious. Their operations involve the following:

1). As the name suggests, a puck lock looks like a hockey puck. It has a thick round body that is very difficult to attack. The puck lock’s round body is your first line of defense.

2). Puck locks have a shackle. However, those shackles are hidden, which means that you can’t attack them with bolt cutters or hammers. You have to take your frustration out on the round body, which is unlikely to succumb to the attacks of a hammer.

3). Some puck locks have a hasp that provides additional shielding, making the lock nearly impenetrable for conventional thieves.

4). The puck lock’s design is incredibly versatile. You can apply it to barn doors, sliding doors, and even the doors of a van.

5). Some people are hesitant to add puck locks to vehicles because their presence tells thieves that the vehicle in question has valuables on the inside. In other words, it can attract unwanted attention.

This is why some consumers paint their puck locks, allowing them to blend into the color of the vehicle. You are less likely to worry if you have a good-quality puck lock.

They are more expensive. But the locks are worth every penny. Even if a thief breaks your puck lock, it will take them a lot of time, increasing their chances of getting caught. The only way the puck lock will fail is if you install it incorrectly.

How To Pick A Puck Lock?

  • Stick the pry bar into the lock on top of the keyway
  • Get a jag pick. It simulates a key
  • Stick the jag pick into the lock. Run the pick in and out of the lock rapidly. If you perform this action enough times, at some point, you will align all the pins in the correct order.

There are more elaborate techniques. But unless you have some experience picking locks, those methods may take you a while to master. It is also worth noting that anyone can pick a puck lock using the method above or any other technique if they have the puck lock in their hand.

This is how most people practice. They will experiment with picking the lock in a safe and comfortable setting. Picking a lock that is attached to a door is more challenging because the lock is in an awkward position.

But your options are limited where puck locks are concerned. Despite what people say, you can cut these tools. They are not impenetrable. You can cut through the lock and guard if you have a decent saw.

You don’t have to use a saw. Any efficient cutting tool can slice through the pin and hasp. However, this method takes too long.
