Lock Unit Cost:
A $173 per-lock investment is assumed, based on typical pricing for ENFORCER® high-security locking solutions.

Real World
Example

Unlock Massive ROI with Long-Term Fleet Security

10-Year NPV-Based ROI → 1,820%

The Problem

One major fleet was losing 140 loads per year, each valued at $281K+, before implementing high-security physical locks.

The Investment

$950,000 one-time cost for locks
Locks last 10 years → $95,000/year when annualized

The Result

Theft reduced from 140 to 10 loads annually
130 loads saved x $281,757 avg. value = $36.6M in annual savings

The ROI

Annual Loss Avoided: $36.6M
10-Year NPV-Based ROI: 1,820%

Key Takeaway

For a fraction of one trailer loss, you can secure your entire fleet for a decade.

What our customers
are saying

“Transporting critical assets at today’s elevated threat level calls for proven security measures. Protocols need to be created and adhered to for cargo in-transit and at rest. At DeSpir, we utilize industry best practices to safeguard our clients’ cargo. This includes securing trailers with hardened padlocks and additional high security locking devices.”

– Ron Devitt
Co Founder & Managing Partner,

Objections That Cost You More Than Locks

Locks are too expensive for a large fleet.

With average cargo theft losses at $214,104 (CargoNet), investing $115–$238 per trailer is a fraction of that cost. Securing 100 trailers? That’s $11,500–$23,800 total, still less than one loss. Plus, strong physical security can support insurance discounts and reduce claim friction.

Locks slow down our drivers.

Seconds to lock. Hours to recover stolen cargo. Our locks are fast and easy to use adding minimal time, while preventing the massive delays of police reports, insurance claims, and customer damage.

Thieves will break in anyway.

Not if you make it hard. Most cargo thefts are crimes of opportunity. A hardened lock shifts attention to the next, easier target. Our locks are built to resist cutting, prying, and tampering.

Locks make trailers look valuable.

Unlocked trailers signal the opposite: easy target. Sophisticated cargo thieves already know how to spot high-value loads. A visible lock is a deterrent.

Tech solutions are better than locks.

Tech alerts. Locks prevent. GPS and sensors help you respond after a breach. Our locks stop the breach from happening. The most secure fleets use both.

We don’t have any theft.

You do, you just don’t want to talk about it.

Cargo goes missing more often than reported. It’s written off as miscounted, misplaced, or misdelivered. But quiet theft is still theft and it adds up. Physical locks don’t just prevent headline-grabbing heists; they stop the everyday losses no one wants to own up to.

Security Stack

Foundational Layer: Physical Security

The First and Strongest Line of Defense

Most cargo theft starts with simple opportunity, and nothing shuts it down faster than high-grade physical barriers. Trailer locks, king pin locks, air cuff locks, and landing gear devices form the bedrock of transportation security, delivering proven ROI by preventing theft before it begins. These rugged, field-tested tools are the essential deterrent every fleet should build around.

Why it matters: Without physical security, the rest of your stack is built on sand.

Technology Layer

Visibility, Control, and Intelligence in Real Time

While locks protect the load, tech protects the plan. Modern systems layer in real-time GPS tracking, temperature and door sensors, geofencing alerts, route risk planning, and cybersecurity protections for fleet data. Technology enables proactive decision-making and rapid response when something goes wrong.

Key tools: Telematics | Geofencing | IoT Sensors | Cybersecurity | Digital Route Risk Platforms

People-Based Security

The Human Element Still Matters

No technology can replace trained, trustworthy people. Background checks, driver protocols, cargo escorts, and incident response training are vital in reducing human-error-based losses and enabling quick action under threat.

Key components: Employee vetting | Driver training | Escort deployment | Security culture

Operational Security

Policy, Partnership, and Proactive Planning

Security isn’t just hardware and software, it’s ongoing process. From collaborating with CargoNet and TAPA to running internal audits and refining SOPs, operational discipline is what connects all the layers of your stack into a cohesive program.

Key actions: Law enforcement collaboration | Risk assessments | SOP enforcement | Threat intelligence updates

Secure Your Fleet with Custom Key Control

At Transport Security, we understand that every fleet has unique security needs. That’s why we offer custom keying solutions built around ABLOY® technology, ensuring that each lock meets the demands of your specific operations, whether you run a single truck or manage a nationwide logistics network.

Why Keying
Matters

Protecting your cargo isn’t just about having strong locks; it’s also about ensuring the right people have the right keys at the right time. A thoughtful keying strategy helps you:  

Prevent Unauthorized Access

Only authorized personnel can open locks, reducing theft and liability risks.

Streamline Operations

A single master key can open multiple locks, minimizing the number of keys your drivers or managers carry.

Enhance Accountability

With well-defined keying systems, you always know who has access to which areas, bolstering compliance and safety.

Our Keying Systems

Keyed Different

Each lock is keyed to a unique key code, ideal for operations needing highly individualized security.

  • Maximum Individual Control: Perfect for high-value cargo or when each lock must remain exclusive.
  • Ideal For: Owner-operators or specific high-risk routes.

Keyed Alike

Two or more locks share the same key, simplifying day-to-day use and reducing the hassle of managing multiple keys and ensuring operational efficiency.

  • Convenient & Efficient: Perfect for fleets, multiple drivers, or shippers when locks are frequently accessed by the same company.
  • Ideal For: Multiple locks on the same truck and trailer or intermodal cargo shipping logistics.

Master Keyed Systems

A master key system offers versatile access control that you can customize to your exact needs. Each lock or group of locks can have its unique key, but a master key can open them all. This approach balances individual security with overarching managerial access.

  • Centralized Control: Fleet managers or authorized personnel can open all locks, while drivers only access locks they’re assigned.
  • Ideal For: Large fleets with multiple routes, terminals or distribution centers.36
