If you manage a building, an access control system Chicago tenants and staff can rely on is the difference between chasing lost keys and controlling every door from a dashboard. This guide explains the main system types, how to choose the right one for your building size, how installation works, and the Chicago-specific code issues property managers need to know before they buy.
The Professional Locksmith has designed and installed access control for Chicago buildings since 2012 as a licensed, bonded, and insured company with Certified Registered Locksmiths on staff. We work with property managers, condo boards, and building owners across the city, from small courtyard buildings to multi-floor commercial properties.
Key Takeaways
Access control replaces physical keys with credentials you can add, restrict, or revoke instantly.
The main options are key card, fob, PIN pad, mobile credential, and biometric, each with trade-offs.
Losing a keyed master forces a costly rekey, while losing a credential is a two-second deactivation.
Chicago fire code and ADA accessibility rules affect how electronic locks must be installed.
Access control integrates with intercoms and cameras for a single, manageable security system.
Why Property Managers Move Away From Keys
Physical keys create three chronic problems for building managers: they get lost, they get copied, and they cannot tell you who came and went. When a tenant with a master key moves out without returning it, you face a full rekey. Access control solves all three issues at once.
The core benefits:
Instant control: add a new tenant or revoke a departed one in seconds, with no locksmith visit needed for each change.
Accountability: an audit trail records who entered which door and when, valuable for disputes, insurance, and security reviews.
Scheduling: doors can lock and unlock automatically by time, so the lobby stays open during business hours and secures itself at night.
These systems build on the same infrastructure as your commercial locksmith hardware, so they work alongside existing deadbolts and exit devices.
The Main Types of Access Control
Each credential type suits a different building profile. Understanding the trade-offs prevents an expensive mismatch.
Key Card and Fob Systems
Cards and fobs are the workhorses of building access. Tenants tap a card or fob at a reader to enter. They are inexpensive per credential, easy to reissue, and familiar to users. The trade-off is that cards can be shared or cloned on older technology, so choose encrypted, modern formats.
PIN Pad Systems
A keypad requires a code rather than a physical credential. Codes are cheap to issue and easy to change, which suits small buildings and back-of-house doors. The downside is that codes get shared among tenants and should be rotated periodically. These pair well with our keyless entry systems hardware.
Mobile Credential Systems
Mobile access uses a smartphone as the key via an app or Bluetooth. There is nothing to print or replace, and remote management is simple. It is ideal for tech-forward tenants and reduces the ongoing cost of physical cards, though it depends on tenants having compatible phones.
Biometric Systems
Biometrics (fingerprint or facial recognition) offer the highest assurance that the credential belongs to the person using it, because it cannot be lent or lost. They cost more and are usually reserved for high-security zones like server rooms, cash areas, or restricted floors.

Choosing the Right System for Your Building
The right choice depends on building size, tenant type, and how the doors are used.
Match the System to Building Size
Small courtyard or two-flat buildings often do well with a keypad or a simple card system at the main entrance. Mid-size buildings benefit from card or fob access with zoned permissions. Large or mixed-use properties usually need a managed platform that combines cards or mobile credentials, scheduling, and integration with cameras and intercoms.
Integrate, Do Not Isolate
The strongest setups connect access control with your existing systems. Tie card readers to your intercom installation so visitors can be buzzed in and logged, and to your security cameras so entry events are captured on video. Electric hardware such as our electric door strikes and automatic door closers make remote release and secure closing reliable. For buildings keeping some mechanical locks, a master key system can coexist with electronic access on select doors.
A Simple Decision Framework
How many doors and tenants? More doors and turnover favor card, fob, or mobile systems over keypads.
What is your turnover rate? High turnover rewards instant credential deactivation.
Do you need an audit trail? If yes, choose a networked system that logs entries.
Are there high-security zones? Add biometrics only where the risk justifies the cost.
Installation and Chicago Code Considerations
Installing access control is not just wiring a reader to a door. It involves life-safety and accessibility compliance that Chicago enforces.
Fire Code and Free Egress
Electronic locks must never trap occupants. Under the National Fire Protection Association Life Safety Code (NFPA 101) and Chicago’s building and fire codes, access-controlled doors on egress paths must fail safe or provide compliant release so people can always exit in an emergency. A qualified installer configures the door to lock intruders out while letting occupants out freely.
ADA Accessibility
The Americans with Disabilities Act and the ADA Standards for Accessible Design set requirements for door hardware, operating force, and reach ranges. Readers and release hardware must be mounted at accessible heights and operable without tight grasping or twisting. Getting this right at installation avoids costly retrofits.
Typical Installation Process
A professional installation generally moves through assessment, system design, mounting readers and electric hardware, running and terminating wiring, programming credentials and schedules, and testing every door for both security and safe egress. Timelines depend on door count and whether the building is occupied.
Frequently Asked Questions
What is the best access control system for a Chicago apartment building?
For most multi-tenant buildings, an encrypted key card or fob system at the main entrance offers the best balance of cost, ease of reissue, and tenant familiarity. Larger or mixed-use properties benefit from adding mobile credentials, scheduling, and integration with the intercom and cameras for full building coverage.
How much does an access control system cost in Chicago?
Cost scales with the number of doors, the credential type, and integration with cameras or intercoms. A single-door keypad is far less than a multi-door networked platform with biometrics. Because every building differs, call (312) 796-0901 for an on-site assessment and an accurate estimate.
Can access control work with my existing locks and intercom?
Yes. Access control is designed to integrate with existing mechanical locks, intercoms, cameras, and electric strikes. A locksmith can keep master-keyed doors where they make sense while adding electronic control to entrances and high-traffic doors, creating one coordinated system.
Are electronic locks safe in a fire or power outage?
Properly installed systems are configured for safe egress, meaning occupants can always exit even during an emergency or power loss. Chicago fire code and NFPA 101 require this. A qualified installer sets doors to fail safe on egress paths and tests every door before handover.
How fast can I remove access for a former tenant or employee?
Almost instantly. Deactivating a lost or returned credential takes seconds in the management software, with no rekeying and no locksmith visit for each change. This is the core advantage of access control over physical keys, especially in buildings with regular turnover.
Conclusion: Take Control of Every Door
For property managers, an access control system Chicago buildings deserve turns key chaos into instant, auditable control. Choose the credential type that fits your building size and turnover, integrate it with your intercom and cameras, and make sure installation meets Chicago fire code and ADA accessibility rules. The result is a building where you add, restrict, or revoke access in seconds and always know who came through the door.
