Keycard Entry Systems for Maryland & DC Businesses

A lost key means a locksmith visit and rekeying every lock it touches. A lost keycard means a 30-second deactivation from your computer, no locksmith, no new keys, no security gap. Teltek installs keycard and key fob entry systems for businesses across Maryland and Washington DC, proximity cards, smart cards, mobile credentials, and cloud-managed access control, giving you full control over who enters, when, and where, with a complete audit log of every door event.

Types of Keycard Entry Systems Teltek Installs

Proximity card systems (RFID) —the most common keycard type for Maryland commercial offices; contactless readers, durable cards, and straightforward credential management
Smart card systems —encrypted chip-based cards offering higher security than standard proximity cards, ideal for regulated or high-security environments
Key fob systems —compact fob credentials that attach to a keychain; same functionality as keycards with a more convenient form factor for many employees
Mobile credential systems —employees use a smartphone app instead of a physical card, using Bluetooth or NFC to unlock doors; no cards to issue, lose, or replace
Hybrid systems —support multiple credential types simultaneously, allowing businesses to mix keycards, fobs, and mobile credentials across the same system

What Keycard Entry Systems Include

A complete keycard entry system is more than a card reader on a door. Teltek designs and installs the full system:

Card readers — mounted at each controlled entry point, reading proximity, smart card, or mobile credentials
Electronic door hardware — magnetic locks, electric strikes, and door position sensors that control and monitor each entry point
Access controller — the hardware that manages credential validation, door schedules, and system rules
Cloud or on-premise management software — the platform where credentials are added, removed, and monitored
Low voltage cabling — the wiring infrastructure connecting every component, installed as part of the same project
Audit logs — a timestamped record of every credential event at every door, searchable and exportable

Keycard vs Mobile Credentials. Which Is Right for Your Business?

Keycards and fobs remain the practical choice for most Maryland businesses, familiar to employees, easy to issue, and straightforward to manage. Mobile credentials are increasingly popular for businesses that want to eliminate physical card issuance entirely, reduce administrative overhead, and appeal to a tech-forward workforce. Most modern cloud-based systems support both simultaneously, giving businesses the flexibility to issue keycards to employees who prefer them and mobile credentials to those who don't want to carry a card.

Cloud-Managed vs On-Premise Keycard Systems

On-premise keycard systems store credential data on a local server or controller, requiring a technician visit for software updates and limiting remote management capability. Cloud-managed systems allow administrators to add or revoke credentials, adjust door schedules, and review access logs from any device, anywhere, without a technician visit. When an employee leaves or a card is lost, access is revoked in seconds from a browser or mobile app.
