Factors to Consider When Buying Puck Locks for Cargo Vehicle

Cargo vehicles typically carry more valuable items than regular commuter vehicles. This is why the security of your car should be a top priority. One of the best ways to enhance the security of your vehicle is to use a puck lock.

However, not all puck locks are created equal. Here are a few tips to guide you in choosing the best lock for your truck.


One of the critical factors that you must consider before you choose a puck lock is the material used to make the padlock. You want to choose a hardy material that is impervious to brute force since it will make it hard for thieves to break the lock.

Some of the most reliable materials that are ideal for making puck locks include stainless steel, fortified aluminum, and nickel.

The hardier the material is, the more impervious it will be to drilling and melting attacks.


You should also pay attention to the design of the lock before you choose one for your vehicle. You want to pick one that has solid construction without any exposed points of weakness.

For instance, chains and shackles can easily be cut, which can compromise the security of your car.

Take time to read a puck lock review before you choose your product. If most consumers like the construction of the lock, you will probably like it too.


The best puck locks offer car owners exceptional convenience. Some convenience features to look for in a lock include keyless locking and opening systems and the ability to rekey the locks. The latter is especially crucial if you will be using multiple locks on the same vehicle.commercial vehicle security locks


Another factor you should keep in mind before selecting a lock is its design. Ideally, the best puck locks are demurely designed.

This is because inconspicuous padlocks do not draw attention to your vehicle, which makes it hard for thieves to suspect that you have valuables in your car.

Puck Locks – FAQ

Are puck locks secure?

Puck locks are among the most secure padlocks on the market. This is because they often have a solid design without any exposure of weak points. Additionally, most such locks are made of heavy metals that are hard to break or melt.

Although many puck locks offer additional security compared to ordinary locks, some offer better protection than others. Top-quality products are better able to withstand picking and drilling attempts, so it might be better to invest in them than purchasing lower quality products.

Can puck locks be rekeyed?

Some puck locks for vans can be rekeyed, while others cannot. You must check the exact specifications of a lock before you purchase it. It is better to have a lock that can be rekeyed as it will offer you extra convenience.

Will drilling cause the lock’s cylinder to pop out?

The level of a lock’s vulnerability to drilling differs vastly depending on the construction of an individual product. Many quality products can withstand hours of drilling without prying open, while others will give way after a few minutes of drilling.

It is better to purchase a quality product that cannot be easily drilled. It may cost some extra money, but it will be worth every extra penny you spend on it.


Finding the right puck lock need not be a hard task if you follow a few tips. Some of the most important ones include robust construction, internal shackles, and a demure design.

Among the products on the list, the best one is the Paclock's 400A Series puck lock. This is because it is made of fortified aluminum and comes with a keyless locking and opening mechanism. It also has a discreet appearance that will not alert anyone about the valuables in your vehicles.
