Choosing the right van lock can be a challenge, especially for fleet managers, tradespeople, and couriers who rely on their vehicles for work. Security is a top priority, as vans often contain valuable tools, equipment, and cargo that can be a target for thieves. While factory-installed locks provide some protection, they are often not enough to prevent break-ins. This is where additional security measures, such as deadlocks and slamlocks, come in.
But which one is the best choice for your business? In this article, we’ll break down the key differences between van deadlocks and slamlocks, their benefits, and which type of lock is best suited for different types of businesses.
Understanding van deadlocks
A Van Deadlock is a mechanical lock that operates independently from the factory-fitted locking system. It consists of a strong bolt that is manually engaged using a key. Once locked, the deadlock cannot be opened from the inside, providing an extra layer of security against thieves who might try to break in by bypassing the vehicle’s main locking system.
Benefits of van deadlocks
- Increased security – Deadlocks add an additional locking point, making it much harder for thieves to force open doors.
- No accidental locking – Because deadlocks must be manually locked and unlocked, they prevent situations where a driver could be locked out of the van accidentally.
- Custom installation – Deadlocks can be fitted to multiple entry points, including rear doors, side doors, and cab doors, providing comprehensive security.
- Best for overnight security – Since they require a key to be locked and unlocked, they are particularly useful for vans left unattended for long periods, such as overnight parking.
- Ideal for high-value cargo – Businesses transporting expensive equipment or sensitive goods benefit from the added security deadlocks provide.
Drawbacks of van deadlocks
- Requires manual operation – Unlike slamlocks, deadlocks do not automatically engage, meaning the driver must remember to lock them.
- Less convenient for couriers – If you frequently need to access your van throughout the day, manually locking and unlocking a deadlock can be time-consuming.
Understanding van slamlocks
A slamlock is a type of van lock that automatically engages when the door is closed. This means that as soon as the driver shuts the door, it is immediately locked and requires a key to be reopened. This feature makes slamlocks particularly popular among delivery drivers and couriers who make frequent stops throughout the day.
Benefits of van slamlocks
- Automatic locking – Reduces the risk of theft due to forgetting to lock the van.
- Convenience for busy drivers – Ideal for couriers and multi-drop drivers who need to quickly access and secure their vehicle.
- Time-saving – Eliminates the need to manually lock and unlock doors, improving efficiency during deliveries.
- Discourages opportunistic theft – Since the doors automatically lock upon closing, thieves have fewer opportunities to gain access.
Drawbacks of van slamlocks
- Risk of accidental lockouts – Because the lock engages automatically, drivers can get locked out of their van if they leave their keys inside.
- Not ideal for overnight security – While slamlocks provide immediate protection, they do not offer the same level of resistance against forced entry as deadlocks.
- Requires high awareness – Drivers need to be mindful of always carrying their keys to avoid inconvenience.
Key differences between van deadlocks and slamlocks
| Feature | Van Deadlocks | Van Slamlocks |
| Locking mechanism | Manual key operation | Automatically locks when door closes |
| Best for | Overnight security, high-value cargo | Delivery drivers, frequent stops |
| Risk of accidental lockouts | No | Yes |
| Security level | Higher (resistant to forced entry) | Moderate (prevents opportunistic theft) |
| Installation points | Rear, side, and cab doors | Primarily cargo doors |
Which lock is right for your business?
Choose van deadlocks if:
- You leave your van unattended for long periods, such as overnight or at a job site.
- You carry expensive tools, equipment, or cargo that requires high-level security.
- You are less concerned with speed and convenience and more focused on maximum protection.
- You want to customize security on multiple access points of your van.
A Van Deadlock is the best choice for tradespeople, contractors, and fleet managers who prioritize security over convenience.
Choose van slamlocks if:
- You make frequent stops throughout the day and need quick access to your van.
- You work as a courier, delivery driver, or in a role where efficiency is crucial.
- You want automatic protection to prevent opportunistic theft during quick stops.
- You are confident that you’ll always have your keys on hand to avoid accidental lockouts.
Slamlocks are particularly useful for high-traffic businesses that require fast and secure access to their vans.
Can you use both locks together?
For maximum security, some van owners choose to install both deadlocks and slamlocks. This provides the best of both worlds:
- Slamlocks offer convenience and immediate security for frequent stops.
- Deadlocks provide reinforced security when the van is left unattended for longer periods.
Fleet managers and high-value cargo transporters often opt for this dual-lock approach to cover all security scenarios.
Installation and cost considerations
The cost of installing van locks depends on the type of lock, the number of doors being secured, and the complexity of the installation. On average:
- Van deadlocks cost between £150-£300 per lock, including professional installation.
- Slamlocks cost between £100-£250 per lock.
Professional installation is highly recommended to ensure that the locks function correctly and provide maximum security. DIY installation may save costs but can lead to incorrect fitting, reducing effectiveness.
Conclusion: making the right choice for your van security
Choosing between a van deadlock and a slamlock depends on your business needs. If you prioritize maximum security and don’t mind manually locking and unlocking doors, a Van Deadlock is the right choice. If you need quick and automatic locking to keep up with a fast-paced delivery schedule, a slamlock is the better option.
Ultimately, both locks provide additional protection beyond factory-installed locks, and in many cases, a combination of both is the best way to keep your van secure. Investing in the right security system today can save you from costly thefts and disruptions in the future.
