Genuine HID ProxKey III 1346LNSMN Proximity Key Fob 50-Pack

In this review the focus is on the Genuine HID ProxKey III 1346LNSMN 50-pack, a bulk solution for organizations that need reliable low frequency access tokens. The bottom line: this pack is for installers, facility managers, and service departments that want consistent, preprogrammed HID proximity fobs with wide reader compatibility and a compact, key ring friendly form factor. The biggest reason to buy is predictable interoperability with HID proximity readers and a high code capacity that reduces duplication risk across deployments.

Key Features

• 50-pack convenience: Buying fifty fobs at once simplifies rollouts and replacement stock for medium to large sites.
• Universal HID compatibility: Works with a broad range of HID proximity readers so the same fob can be used across many doors and readers.
• Compact key ring design: Small, durable fobs are easy to carry and attach to a key ring for daily use by staff.
• High code space: Supports up to 85-bit formats with over 137 billion codes, reducing chances of code collision in large deployments.
• Preprogrammed facility code: Arrives with a preassigned facility code and 50 card data L entries to speed commissioning.
• Read range variability: Typical maximum read ranges vary by reader, enabling flexibility depending on reader model and installation needs.

Who It's For

This pack is suited to security integrators, property managers, and institutions replacing or expanding proximity-based access control systems that already use HID readers. The 50-pack format keeps per-piece costs down and simplifies inventory for scheduled rollouts or refresh programs.

It is not aimed at single-home users or buyers who require visual numbering on every token for user-managed tracking, since fob numbers are random and not printed on the fob. Also choose differently if you need high-frequency or smartcard functionality rather than low frequency 125 kHz prox operation.

Pros & Cons

Pros

• Genuine HID manufacture ensures consistent interoperability with HID proximity readers.
• Bulk 50-pack reduces administrative overhead when provisioning many users.
• Supports large code formats, helping avoid duplication across systems.

Cons

• Key fob numbers are random and not printed, which may complicate onsite tracking without external labeling.
• Low frequency prox technology may not meet needs where smartcard or higher-security credentials are required.

Frequently Asked Questions

Are these fobs compatible with existing HID readers?
Yes, they offer universal compatibility with HID proximity readers that operate on the same low frequency 125 kHz prox standard.

Do the fobs come preprogrammed?
Yes, this 50-pack includes Card Data L entries and arrives with a preassigned facility code to simplify commissioning.

Is each fob uniquely numbered on the plastic?
No, key fob numbers are random and are not printed on the fob, so external labeling or a provisioning spreadsheet is recommended.
