Lock and Unlock Services: Eliminating the Risk of Unsecured Secondary Gates

Updated: 25 Jun 2026 · Category: Mobile Patrols / Lock & Unlock

Staff members in a rush can easily forget to secure secondary gates, leaving your property wide open. Here is how professional lockup services solve the problem.

Key Takeaway: Lock and unlock services involve hiring professional security guards to visit your commercial site at specific times to open the premises in the morning and lock all doors, windows, and gates in the evening, ensuring the property is fully secured and the alarm is set overnight.

In large commercial properties or manufacturing yards, there are often multiple gates, side doors, and roller shutters. Relying on tired employees to check every lock at the end of a long shift is a major risk. A single gate left unlocked can invalidate your insurance policy and invite intruders inside.

1. The Risk of Staff Keyholders

Tasking staff with locking up the site creates several vulnerabilities:

Complacency: Employees are focused on getting home. They may miss a secondary gate, skip checking fire exits, or fail to set the alarm correctly.
Safety Hazards: Lone workers locking up in the dark are vulnerable to confrontation or injury.
Key Control Issues: Distributing keys and alarm codes to multiple employees increases the risk of loss or unauthorized duplication.

2. The Professional Lockup Protocol

A professional Lock & Unlock service removes this burden. An SIA-licensed officer arrives at the end of the working day. They perform a thorough sweep of the premises:

Building Sweeps: They verify that all staff have left, lights and heating are turned off, and windows are closed.
Gate Lockdown: They lock all secondary entrances and padlocks.
Alarm Setting: They set the alarm system and lock the main gates.

Operational Security and Staff Well-Being

Implementing a professional lock and unlock service supports staff well-being and operational security. Employees should not be responsible for carrying keys, setting complex alarms, or being the first to enter a dark building. A professional security officer manages these tasks, performing a pre-opening sweep to ensure the premises are safe before staff arrive, and securing all windows and fire doors before locking up at night.

This service reduces the risk of key duplication or loss, and ensures that the alarm system is set correctly every evening. By outsourcing this responsibility, business owners protect their staff and ensure that the building is secured in a consistent, professional manner.

Frequently Asked Questions

Q: What are the safety risks of making employees responsible for locking up business premises?

A: Employees carrying keys are vulnerable to opportunist assaults, theft, or coercion. They may also face safety risks when entering a dark building alone or setting alarms under pressure.

Q: How does a professional lock and unlock security service work for commercial buildings?

A: An SIA-licensed security officer attends the site at set times to perform a pre-opening safety sweep, disable alarms, and open gates, or to secure all doors, set alarms, and lock up at night.

Q: What checks does a security guard perform during a building opening sweep?

A: The guard checks for signs of out-of-hours intrusion, inspects fire exits for obstructions, verifies utility lines are safe, and ensures the premises are clear before staff enter.

Q: Can a professional unlock service help reduce commercial property insurance premiums?

A: Yes. Many insurers offer premium discounts or lower deductibles when a certified security provider manages building opening and locking, as it reduces the risk of security breaches.
