Cost-benefit analysis
What is a cost benefit analysis?
A cost-benefit analysis (CBA) is a systematic approach to evaluating the financial and operational trade-offs of a decision by comparing the costs incurred against the benefits gained. This method helps organizations assess the value of an investment and make informed decisions by quantifying both direct and indirect impacts in monetary terms.
Cost benefit analysis of 5G IoT smart padlocks
In our analysis, the cost-benefit analysis (CBA) highlights the economic advantages of transitioning from traditional metal key padlocks to 5G IoT smart padlocks.
By comparing the implementation costs of smart padlocks to the savings achieved in maintenance, fuel, and operational inefficiencies, the analysis reveals a clear return on investment (ROI) within just two months, underscoring the transformative potential of this innovative technology.
​
In dynamic environments such as construction sites, warehouses, and industrial complexes, maintaining security while optimizing efficiency remains a constant challenge. One recurring issue is the loss of materials from these sites, often due to gaps in security.
​
For large organizations relying on traditional metal keys, additional inefficiencies arise as contractors and technicians frequently spend significant time driving to and from head offices—sometimes across town—to collect keys at the start of the day and return them at its end.
These logistical delays not only postpone critical tasks but also lead to increased fuel expenses, vehicle wear, and lost productivity. Such inefficiencies exacerbate operational challenges and contribute to unnecessary costs, making a compelling case for smarter, more efficient access control solutions.
​
The Problem at Hand
One of the core issues lies in large companies, especially large critical infrastructure companies like gas, water, electricity, rail, and telecommunication companies traditional reliance on metal keys for access control. Metal keys present several challenges, such as:
-
Uncontrolled Duplication: Contractors or employees might create unauthorized copies for convenience, enabling unauthorized access.
-
Neglected Security Protocols: Personnel may leave doors unlocked to avoid the hassle of retrieving and returning keys, exposing the site to external risks.
-
Lack of Accountability: When materials go missing, there is no effective way to determine who accessed specific areas or when, resulting in ambiguity and inefficiency.
Critical Implications
The inability to track who is on-site and at what times creates significant security and operational vulnerabilities:
-
Financial Loss: Missing materials directly impact project budgets and timelines.
-
Operational Inefficiency: Time is wasted investigating incidents and reallocating resources.
-
Reputational Risk: Persistent security issues can damage stakeholder confidence.​
​
Why Traditional Metal Key Solutions Fall Short
Metal keys lack real-time monitoring, customizable access controls, and the ability to provide an audit trail of entry and exit logs. Without these capabilities, companies are left with a reactive approach to security rather than a proactive one.
​
The following cost-benefit analysis example provides a comprehensive breakdown of the challenges associated with traditional metal key systems for large companies and the advantages of transitioning to 5G IoT smart access solutions.
Using detailed graphics, tables, and visual aids, this presentation illustrates the inefficiencies, hidden costs, and potential risks of metal keys while showcasing the streamlined operations and enhanced security offered by our 5G IoT smart padlocks.
A typical construction site/critical infrastructure site scenario


Contractor A believes that duplicating metal keys for the site is a more convenient and cost-effective solution. To save time, he also makes an additional key copy and hands it to his cousin, allowing him to drop off materials without supervision.
​
Contractor B, frustrated by the daily need to drive across town to pick up and return keys, often leaves the door unlocked, prioritizing convenience over security.
​
The Cleaner is aware of where spare keys are stored on certain sites. Exploiting this knowledge, they use a clay mold to replicate the key and later produce a 3D-printed version, enabling unauthorized and unmonitored access anytime.


What do employees have to say about metal key access inefficiencies
​

Ground Engineers
"Metal keys are so inconvenient and insecure"
"Exchanging keys often requires long, unnecessary drives, wasting time, fuel, and productivity. Traditional metal keys are also prone to unauthorized duplication or 3D printing, enabling illegal access and compromising security. These outdated systems create inefficiencies and risks that modern businesses cannot afford in today’s fast-paced, security-conscious environment."

Contractors
"Metal keys are so inefficient and time consuming"
"Traditional key management can be time-consuming, with lengthy paperwork and administrative tasks for access approval processes. Then of course there is the inconvenience of picking up and returning keys, often outside office hours. Additionally, losing a key can result in fines of up to $250 (this is the cost for locksmiths to come out and replace locks, further adding to the inefficiency and cost of managing physical keys."

Mid-Managers
"Metal keys lack visability and control"
​It’s difficult to confirm if workers arrive on-site as scheduled, creating accountability gaps. Managing access/keys paperwork for hundreds of workers is overwhelming and time-consuming. Additionally, there’s no way to ensure doors are locked securely, leaving sites vulnerable to theft and unauthorized access. Traditional methods fail to provide the visibility and control modern businesses need.

Executive Managers
"Metal keys results in high costs/high risks
"Customer complaints erode trust, leading to a drop in revenue. Poor safety measures result in higher insurance premiums and damage to the company’s reputation. Lost keys can incur locksmith callout fees of $200 or more, further adding to costs. These risks highlight the inefficiencies and financial burdens of traditional access management systems with metal keys"

Calculations of net benefits
The provided calculations below demonstrates the substantial annual benefits of optimizing maintenance operations for a typical critical infrastructure company across a nationwide network of 10,000 sites (the sites can simply be for example a meter box, a street cabinet, or a gate securiing a power station or the like). By streamlining processes and reducing inefficiencies with Digital Keys smartlocks significant savings in both time and costs are achieved, highlighting the value of improved operational efficiency. The total projected savings calculated below underscore the financial and logistical advantages of installing Digital Keys smartlocks.

Achieve ROI in Just 2 Months with 5G IoT Smart Padlocks
The calculations above demonstrates the substantial cost-saving potential of replacing traditional metal key padlocks with 5G IoT smart padlocks across 10,000 sites. Currently, the maintenance costs for metal key padlocks amount to approximately $9,276,000 annually ($773,000 per month). By transitioning to 5G IoT smart padlocks, which cost $169 per unit the initial investment totals $1,690,000.
​
With estimated total savings of $9,276,000 per year from reduced maintenance and operational inefficiencies, organizations can expect to achieve a return on investment (ROI) within approximately two months of implementation.
​
It’s important to note that this ROI calculation only considers maintenance costs and excludes significant savings from eliminating daily tasks associated with metal key management, such as key pick-up and drop-off at head offices and the HR/mid-manager time spent managing key distribution and tracking. When these additional factors are accounted for, the ROI becomes even more compelling, emphasizing the transformative value of adopting IoT smart padlocks.
