Padlocks and deadbolts were invented before electricity. Remarkably, a significant percentage of commercial construction sites still rely on them as the primary barrier between their high-value assets and anyone motivated enough to bypass them with a bolt cutter or a copied key.
For Illinois contractors in 2026, relying on mechanical locks is not a budget decision. It’s a security gap.
Here’s the complete breakdown.
Traditional Locks: Where They Belong and Where They Don’t
Mechanical locks have legitimate applications. They are simple, inexpensive, and require no power or network infrastructure. For a garden shed or a low-risk storage closet in a secured building, a padlock is appropriate.
For a construction site where $300,000 worth of equipment is staged overnight, where 30 different subcontractors have had access over the past three months, and where you have zero visibility into who is coming and going — mechanical locks are a liability.
-
- No audit trail — you cannot determine who entered or when
- Keys can be duplicated at any hardware store without your knowledge
- Lost or stolen keys require full rekeying — every lock, every copy
- No instant deactivation — if a terminated subcontractor has a key, they still have access
- No remote management — lockouts require physical presence
- No integration with video or alarm systems
Electronic Access Control: Security Intelligence for Contractors
Electronic access control replaces the mechanical key with a managed credential system — keycard, fob, PIN code, mobile credential, or biometric. The hardware difference is significant. The operational difference is transformative.
-
- Complete audit trail: every entry event logged with timestamp, credential, and user identity
- Instant deactivation via software — a terminated employee or subcontractor loses access in seconds from your phone
- Time-based access rules — automatically prevent after-hours access without manual intervention
- Multiple credential formats — cards, fobs, mobile credentials, biometrics for different security levels
- Remote management via virtual keypad — create, modify, and revoke access from anywhere
- Integration with video: access events cross-referenced with camera footage automatically
- Integration with intrusion: access denial after hours triggers alarm protocol

The Subcontractor Management Problem That Access Control Solves
Most contractors manage subcontractor access with a combination of physical keys, shared gate codes, and verbal instructions about who can access what. This system works until it doesn’t and when it doesn’t, you often don’t know until something is missing.
Sentry Security’s access control platform gives contractors complete command of the credential lifecycle. Every subcontractor gets a digital credential with a defined access scope and schedule. Their access automatically expires at the end of their phase. Every entry they make is logged. Every attempted after-hours access triggers an alert.
That’s accountability. That’s what professional site management looks like in 2026.
