Keri Systems PXL-250 / Keri Classic 26-bit (K-Format) Compatible Cards & Fobs
Keri Systems 26-bit (KC-26X / PSK-3) cards use the industry-standard H10301 Wiegand format, compatible with Keri IntelliProx 2000 controllers and any standard Wiegand reader.
Keri's 26-bit credential line (designated 'K-format' or the '26X' series) is fully compliant with the open 26-bit Wiegand H10301 standard, operating at 125 kHz. Because this is an open, non-proprietary format, our compatible cards provide identical system compatibility at value pricing, with no OEM-only sourcing restriction.

What is the difference between Keri 10X and 26X format cards?
The KC-10X series uses Keri's proprietary MS format for PXL-500 Tiger and MS-series readers, while the KC-26X series uses standard 26-bit Wiegand (H10301) for use with IntelliProx 2000 controllers or any standard Wiegand reader. Our 26-bit compatible cards work with the 26X/IntelliProx 2000 side of Keri installations.
Can Keri 26-bit cards work on non-Keri access control systems?
Yes — standard 26-bit Wiegand is the most universal access control format. A Keri 26-bit card will work on HID, Honeywell, Lenel, DSX, Bosch, and virtually any other Wiegand-compatible controller.
Are these cards pre-programmed with a site code?
Yes, we offer cards pre-programmed with your specified site code and sequential card numbers, matching your existing Keri 26-bit credential database.
