This fob is pre-encoded 26Bit, Facility Code #100, Number Range Varies. 

The Allegion 7610 26-Bit Proximity Key Fob is designed for seamless integration with Schlage and Allegion systems utilizing standard 26-bit proximity formats. Programmed with a fixed facility code of 100, these key fobs are specifically configured for systems that require exact facility code matching for proper credential recognition. This ensures consistency across an existing card population but also means that any additional or replacement fobs must match both the 26-bit format and facility code 100 to function correctly.

The 26-bit format remains one of the most widely used credential structures, offering broad compatibility across HID 125 kHz proximity readers and access control platforms. With a defined facility code and limited card number range, this format provides a structured and predictable credential system that is easy to manage within smaller to mid-sized deployments. Operating on reliable 125 kHz proximity technology, these key fobs deliver consistent, contactless performance in a compact and durable design—ideal for everyday use in commercial buildings, multi-tenant properties, and secured facilities where format precision and facility code alignment are critical.
