Smart Fleet Key Management with Biometric Key Cabinets: Saudi Electricity Company (SEC)

Shared vehicles are an indispensable asset for enterprise field visits, network maintenance, and site-related operations across utility providers. In large-scale operations such as those at Saudi Electricity Company (SEC), keeping shared fleet vehicles ready, secured, and properly accounted for is critical to operational continuity.

When physical vehicle keys are handed over through manual registers, spreadsheets, or informal custody exchanges, verifying who is in possession of a key, when it was taken, and whether it was returned on schedule becomes an uphill operational battle.

To establish full operational control, AIED deployed an intelligent Biometric Electronic Key Cabinet for Saudi Electricity Company (SEC). The solution brings key access, user permissions, and transaction records into a unified digital workflow—replacing loose physical keys with individually locked slots, multi-factor identification, and detailed timestamped audit trails.

Managing shared vehicles effectively requires knowing not only where vehicles are driven, but also having strict accountability over the physical keys that authorize access to them. When vehicle keys are left on hooks, in unlocked drawers, or passed directly from one technician to another without recorded checkout, fleet managers lose visibility over availability and usage patterns.

By bringing key access, user permissions, and transaction records into an automated digital process, AIED’s electronic key cabinet enables SEC to maintain an unbroken custody record for every vehicle key. The automated system also creates an actionable data trail that supports data-informed fleet planning, maintenance scheduling, and daily resource allocation.

Prior to adopting electronic key management, manual or informal handovers created operational blind spots and placed an administrative burden on site dispatchers. Teams frequently spent valuable time searching for misplaced keys, cross-checking hand-written logbooks, or following up when field teams returned vehicles late.

Key operational challenges included:

AIED deployed an advanced Biometric Electronic Key Cabinet to replace informal key handling with a controlled, digitally recorded process. Each fleet vehicle key is attached to a secure electronic key fob and assigned to a configured slot inside the reinforced cabinet. Mechanical locking mechanisms ensure that only pre-authorized users can release a specific key.

The deployed unit is an enterprise-grade, wall-mounted electronic key management cabinet designed for continuous indoor commercial operation. It incorporates high-grade steel enclosure construction, an intuitive 7-inch Android color touchscreen, and an integrated multi-biometric sensor suite.

Over a three-month operational evaluation period spanning August through October 2025, the electronic key cabinet recorded a total of 191 key issues across eight shared vehicles and nine anonymized employees (designated U1 through U9). The resulting transaction history provides an objective, data-backed view into vehicle demand distribution, peak operational hours, and user booking behaviors.

Transaction records reveal a marked concentration of vehicle demand during early morning dispatch, followed by a concentrated return period around midday:

• Morning Issuance Peak: 87 of 191 total key issues (approx. 46%) occurred between 8:00 AM and 10:00 AM. Broadening the window shows that 139 of 191 issues (approx. 73%) took place between 7:00 AM and 11:00 AM.
• Busiest Individual Issue Hour: The peak single hour for vehicle departure is 9:00 AM – 10:00 AM, with 60 key checkouts recorded.
• Midday Return Window: Vehicle check-ins concentrate strongly around lunchtime, with 95 of 191 returns (approx. 50%) completed between 12:00 PM and 2:00 PM.
• Busiest Individual Return Hour: The single peak hour for vehicle return is 1:00 PM – 2:00 PM, with 49 returns logged.

Operational Planning Insight: These distinct diurnal rhythms demonstrate that fleet dispatch support and vehicle staging must be fully prepared prior to 8:00 AM. Conversely, routine maintenance, inspections, and vehicle washing should be scheduled outside the primary 8:00 AM – 2:00 PM operating window to prevent vehicle shortages during field service hours.

An essential revelation from the review data is the uneven distribution of bookings across available vehicles and personnel:

• Demand Concentration: Just three vehicles—identifiers E01191, E01175, and E01192—accounted for 129 out of the 191 total bookings, representing approximately 68% of all fleet usage.
• Dedicated vs. Shared Patterns: Several vehicles were predominantly used by a single user, suggesting that despite being categorized as shared pool vehicles, they functionally operated as assigned vehicles. In contrast, user U4 demonstrated true pool usage by actively booking across all eight vehicles.
• Data Reconciliation Note: Preliminary reports exhibited slight variance between narrative summaries and tabulated raw booking exports. AIED advises validating vehicle totals against raw logs before making permanent fleet reallocations or decommissioning decisions.

Analyzing key checkout duration provides vital intelligence on driver habits and vehicle turnaround:

Overall, 93% of all vehicle bookings conclude within six hours. Across the entire fleet, the average booking duration stood at approximately 3.4 hours. However, notable variances emerged: User U6 averaged 6.30 hours per booking, and User U5 averaged 5.31 hours. Establishing mandatory digital justification and supervisor approvals for bookings projected to exceed 6 hours will ensure vehicle availability for rotating field teams.

Fleet Sizing Benchmark: Average daily fleet demand stabilized at approximately four concurrently active vehicles. AIED recommends establishing an initial planning baseline of five vehicles per site—four active operational vehicles plus one designated standby unit—to maintain resilience during routine servicing and unexpected demand spikes.

To maximize the long-term return on investment from this technology, AIED proposes seven strategic operational enhancements:

Intelligent electronic key management represents far more than physical key security. When key transaction data is recorded systematically with timestamps and driver identity, it transforms simple hardware records into strategic fleet intelligence.

Through this deployment, AIED has empowered Saudi Electricity Company (SEC) to eliminate informal key custody, enforce driver accountability, and establish actionable data benchmarks for fleet optimization. The next phase will link key cabinets directly into corporate booking portals and predictive maintenance pipelines—paving the way for fully autonomous fleet management.
