Managing who has access to a property is the most fundamental job of security systems. In today’s world, access control systems go far beyond traditional lock and key, providing smarter, safer, and more flexible ways to regulate entry while offering property owners greater peace of mind. But while most are fairly straightforward, they can seem daunting at first glance. Here’s a complete guide to modern access control systems, how they work, and how you can use them to protect your property.
What Are Access Control Systems?
At its core, an access control system is a method of verifying identity and granting or denying entry to a building or secured area. Instead of depending on a single key, these systems use technology such as security codes, cards, biometrics, and mobile apps to decide who should be let in.
Different Types of Keyless Entry Systems
Modern access control systems come in many forms, each suited to different needs — and each with its own pros and cons.
Keypad Systems
Keypad systems require users to enter a PIN or code to unlock a door. They’re popular for small businesses, multi-tenant buildings, and service areas because they’re inexpensive and easy to install. Many models allow temporary or rotating access codes so you can manage short-term access without issuing physical credentials.
Pros:
- Budget-friendly
- No cards or devices to lose
- Easy to update or revoke access codes
Cons:
- Codes can be shared or stolen
- Users may forget their PIN
- Requires regular code changes to stay secure
Card or Fob Readers
These systems use RFID cards or fobs that users tap or swipe at the reader. They’re fast, familiar, and widely used in office buildings, warehouses, and secure rooms. Administrators can easily program or deactivate credentials, making them ideal for environments with a lot of users.
Pros:
- Quick, touch-free entry
- Easy to issue or deactivate credentials
- Good balance of security and convenience
Cons:
- Lost or stolen cards need replacement
- Users must carry a physical item
- Some older systems can be cloned without proper encryption
Biometric Systems
Biometric access control relies on unique physical traits — like fingerprints, facial recognition, or iris scans — to verify identity. These systems offer strong authentication and eliminate the need for keys or badges, making them common in high-security or high-traffic areas.
Pros:
- High level of security
- No keys or cards to lose
- Fast verification in busy locations
Cons:
- More expensive than other options
- Can raise privacy concerns for some users
- May be affected by lighting, gloves, or dirty sensors
Mobile Access
Mobile access control lets users unlock doors with a smartphone app, Bluetooth, NFC, or digital credentials stored in a cloud platform. It supports remote management and audit trails and appeals to businesses looking for modern, flexible systems without issuing physical badges.
Pros:
- Very convenient for users
- Remote credential management
- Reduces the need for physical cards or keys
Cons:
- Requires users to own a smart device
- Needs a reliable app or wireless connectivity
- May require ongoing software subscriptions
The Benefits of Security Upgrades
Access control systems offer advantages beyond just keeping your doors locked. They also allow you to:
- Limit access to only approved individuals
- Stop managing physical keys
- Track who accessed certain areas and when
- Instantly grant, revoke, or adjust access
How to Choose the Right Access Control System
The best access control system depends on the type of property, the number of users, and the level of security required. For a small business, a keypad or card reader may be enough. Larger organizations may prefer a layered system that combines multiple technologies for added protection and customization.
The Future of Property Security
The future of access control lies in smart, connected technology. Cloud-based management, touchless entry, and integration with building automation systems are becoming increasingly common, giving property owners more control than ever before.
Access control systems provide a modern way to protect your people, property, and assets. By replacing outdated lock and key setups with more flexible solutions, you can improve security and gain added convenience — and at a much lower barrier to entry than you may think.
