Design and Build Quality
We appreciate the ProxPro shape because it has been widely used for many years and is familiar to technicians and end users alike. The HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad carries that familiar profile and adds a keypad without making the unit bulky or unintuitive. We note that the materials feel durable and that the faceplate is designed to resist tampering when properly mounted.
Keypad Functionality
We find the keypad adds a layer of authentication that is useful in multi-factor setups or where card sharing is a concern. The keypad is tactile enough for confident key entry and includes basic feedback via beeps and LED indicators to confirm input. We recommend planning for PIN management in the access control software and deciding whether PINs will be required in addition to cards or used as a fallback.

Installation and Setup
We prefer products that reduce setup time, and the 5355 series typically offers a streamlined installation process. The unit mounts to standard single-gang boxes or surface backboxes, and it uses conventional wiring to power the reader and carry Wiegand signals to the access control panel. We advise reading the wiring diagram carefully and verifying power supply capacity, especially when multiple readers or door devices are on the same circuit.
Wiring and Compatibility
We emphasize checking wiring distances and voltage drop when installing multiple readers. The HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad usually accepts 5–16 VDC, but most installations use 12 VDC. We suggest keeping run lengths within recommended limits for Wiegand signaling and using shielded cable in noisy electrical environments.
Mounting Tips
We recommend mounting the reader at a comfortable height and ensuring there is enough clearance for both card presentation and keypad use. We also advise routing wires through the backbox and securing them with proper strain relief. If the mount will be outdoors or in exposed areas, choose a weather-resistant backbox and ensure gaskets are used to keep moisture out.
Performance and Reliability
We value predictable operation, and the HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad is generally dependable in day-to-day use. Read range for HID prox cards tends to be consistent, and the keypad performs well for PIN entry without frequent mis-entries. We recommend verifying card compatibility and testing multiple cards to ensure they all read reliably in the intended mounting location.
Read Range and Sensitivity
We note that read range depends on the card type, orientation, and mounting surface. Proximity read ranges typically meet the needs of door-entry systems but are not intended for long-range or hands-free scenarios. We suggest testing the actual read range with the card types you plan to deploy, placed in their normal orientation (wallet, badge holder, etc.).
Environmental Resilience
We find the ProxPro reader performs well in typical indoor and sheltered outdoor environments. Temperature tolerance and water resistance are sufficient for many installations, but for fully exposed outdoor locations we recommend an enclosure specifically rated for harsh environments.
Security Capabilities
We feel security is the most important factor for an access control device, and the HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad contributes both card-based and PIN-based authentication. While prox credentials are widely used, they are not as secure as modern smartcard or encrypted technologies; adding a keypad helps mitigate unauthorized entry through card cloning or sharing.
Encryption and Data Protection
We note that standard 125 kHz prox formats do not support strong mutual authentication or encryption by default, so the security profile of a prox reader is tied to the credential format and the back-end system. We recommend assessing whether prox technology meets your security policy or if migrating to smartcard/contactless (e.g., iCLASS, MIFARE DESFire) is more appropriate. If prox technology is adequate for your facility, adding PIN requirements and logging can enhance accountability.
Anti-Tamper and Physical Security
We like that the housing is designed to be mounted securely and can be installed with tamper detection wiring in some setups. We advise integrating tamper sensors and ensuring the reader wiring is protected to reduce the risk of bypass or tampering attacks.
Integration and Compatibility
We want installations to be smooth, so ensuring compatibility with controllers and management software is key. The HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad typically interfaces via Wiegand and supports common bit formats. We recommend verifying the required bit length and facility code configuration with the access control system or panel vendor before commissioning.
Working with Common Panels
We find that most modern panels will accept Wiegand from a ProxPro reader, but some systems may need a specific format or translator module to read different HID or third-party credentials. We recommend pre-configuring the reader format to match the controller or setting the controller to accept the reader’s default format.
Credential Management
We advise planning credential issuance and PIN assignment workflows before installing readers. The reader merely presents data to the panel; the panel is where access rights and PIN validation happen. Ensuring the database is clean and duplicates are handled reduces confusion and helps users adapt quickly.
User Experience and Accessibility
We prioritize ease of use for end users, and the HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad tends to be straightforward. The card presentation is quick, and the numeric keypad is accessible for most users. We suggest labeling or instructing users on the required action (card only, PIN only, or card + PIN) and ensuring ADA-compliant mounting heights.
LED and Audible Feedback
We like clear feedback when users present a badge or enter a PIN because it removes doubt and reduces repeated attempts. The reader provides visual LED cues and audible beeps that can be adjusted or muted depending on the installation. We recommend aligning the feedback behavior with the system policy so users know exactly when an entry is accepted or denied.
Typical Use Cases
We find the HID 5355AGK00 ProxPro 5355 Proximity Card Reader with Keypad fits many scenarios where straightforward, reliable access control is needed. Good use cases include small office buildings, internal doors like server rooms or storage areas, gated community entry points with attendant controls, and retrofit applications where upgrading wiring or mounting is constrained.
Multi-Factor Requirement Areas
We advise deploying the reader where a second factor is helpful — for example, combining card and PIN for sensitive rooms like labs, finance offices, or IT closets. We also recommend using the keypad for timed PIN changes or temporary guest PINs, controlled through the access management system.
