Discover the key differences between Slam Locks vs Deadlocks. Understand the workings, pros, and cons of each for better van security across the UK.

What Are Slam Locks?

Slam locks are a simple, strong and dependable way to secure vans, making them a popular choice across the UK. Slam locks lock doors automatically when they're closed. Unlike traditional locks, slam locks use a mechanical system that activates as soon as the door shuts. This simple design makes them both reliable and efficient for everyday use. 

A typical slam lock system is made up of a few basic components. The main parts include a metal latch, a striker plate, and a spring mechanism. When the door is open, the latch is held back, and as soon as the door is closed, the spring pushes the latch forward into the striker plate. This action locks the door securely without any extra effort from the driver.

Additionally, some slam locks have a secondary key-operated mechanism that provides extra security and ensures that the van remains safe in busy or unsafe areas.

What Are Deadlocks?

Deadlocks are mechanical locks that need to be operated with a key or a manual lever. When you use a deadlock, you use a key to lock the door firmly. This means the lock has no moving parts, which makes it difficult for intruders to force it open.

Slam Locks vs. Deadlocks: Which is Best for Your Van?


Deadlocks require you to actively lock the door, and use a key to both lock and unlock it. This extra step can seem less convenient, but it offers more protection for your vehicle. 

The manual operation makes it harder for someone to break in, as the lock can't be opened without the correct key.

On the other hand, slam locks are easier to use since they lock automatically. However, if the spring mechanism wears out or fails, the door might not lock as securely. 

Some van owners choose to install both slam and deadlocks so that they get the convenience of a slam lock and the extra security provided by a deadlock.

Pros and Cons of Slam Locks

Slam locks lock automatically when a van door is closed. Since the lock activates automatically, there's no need to stop and manually secure the door - this can be especially useful when drivers are in a hurry or in traffic. Slam locks typically have a metal latch and a spring that pushes the latch into place when the door shuts. This design can withstand the harsh weather conditions of the UK without failing or becoming damaged.

However, slam locks depend on a spring mechanism, and if the spring wears out or is damaged, the lock may not work properly. Regular checks and maintenance are a good way to ensure that the lock remains in good condition and doesn't compromise your van's safety. While slam locks are convenient, they might not always provide the same level of security as a manual deadlock.

Slam locks are convenient, durable, and are well-suited for busy drivers. However, drivers must be aware of the need for routine maintenance in order to keep the lock functioning properly.

Pros and Cons of Deadlocks

One of the main benefits of using a deadlock is its high level of security. When the lock is used, it holds the door firmly in place with a strong metal mechanism, making it difficult for an intruder to force the door open.

Pros and Cons of Deadlocks

Another advantage of deadlock locks is the control they give to the driver. Since the door must be locked with a key, the driver is fully aware that the van is safe and secure.

However, there are also some drawbacks to using a deadlock, such as the inconvenience of having to use a key every time you want to lock or unlock your van.

There's also the risk of losing the key, which could leave you unable to access your van until a replacement is obtained. A deadlock can also become difficult to use during rain or cold temperatures as moisture can affect the lock.

Deadlock locks provide strong, reliable security and give drivers complete control over locking their vans. However, the need to use a key each time can be inconvenient, especially in poor weather. Therefore, drivers should carefully weigh these pros and cons when deciding if a deadlock is the right security choice for them.
