The short answer: if you have more than a handful of employees, or staff turnover of any kind, electronic access control (key fobs, cards, or phone-based credentials) almost always pays for itself compared to traditional keys. You can add or remove someone in seconds, set schedules, and see who opened which door and when.
Most of the business owners we talk to don’t start out asking about access control. They start with a problem: a former employee never returned their key, a door was found unlocked overnight, or they need to know who was in the building on Saturday.
Option 1: Traditional Keys
Good for: very small offices with one or two trusted people and almost no turnover.
The downsides:
- Keys get copied, lost, and not returned
- Re-keying every time someone leaves gets expensive fast
- No record of who came in or when
- No way to limit access to certain hours or rooms
Option 2: Key Fobs and Cards
Good for: most small and mid-size businesses, retail, offices, and multi-tenant buildings.
Each person gets their own fob or card. Lose one? Deactivate it and issue a new one. No locksmith needed.
What you gain:
- Instant add/remove. An employee leaves at 5 p.m., their access ends at 5:01.
- Schedules. Staff can get in during business hours; managers can get in anytime.
- Zones. Keep the server room, stockroom, or office files restricted.
- Audit trail. See exactly who opened which door and when.
Option 3: Mobile Credentials (Your Phone Is the Key)
Good for: businesses that want the most convenience and the least hardware to manage.
Employees open doors with a smartphone app, often just by tapping or approaching the reader. There’s nothing to lose or hand back, and you can manage everything from anywhere. Many systems let you use both fobs and phones, which is useful if some staff prefer a physical credential.
Things to Think About Before You Choose
- How many doors? Start with the main entry and any sensitive rooms; you can expand later.
- Cloud vs. on-site management. Cloud-based systems let you manage access from your phone; we can help you decide.
- Integration. Access control works best when it’s tied to your alarm and cameras, so a door event can pull up the matching video.
- Fire and building code. Doors must still allow free exit and work properly with your fire system. This is one reason professional installation matters.
A Typical Small Business Setup
For a typical Long Island office or retail space, we often start with a reader on the front and back entrances, plus one interior door like a stockroom or IT closet, managed from a cloud app and integrated with the existing alarm and cameras.

Frequently Asked Questions
Can access control work with my existing doors and locks?
Often, yes. Most doors can be fitted with electric strikes or electrified hardware. We’ll evaluate each door during a site visit.
What happens if the power or internet goes out?
Properly designed systems include battery backup, and doors are configured to meet code for safe exit. Many readers also store credentials locally so they keep working during an internet outage.
Is access control only for large companies?
No. Some of our access control customers have fewer than ten employees. The ability to cut off access instantly is valuable at any size.
