25 pcs 26 Bit Proximity Key Fobs - 26-bit H10301 ISOProx Compatible

In this review the reviewer tested the 25 pcs 26 Bit Proximity Key Fobs and found them best suited for installers and facility managers who need budget replacement fobs formatted to the common 26-bit H10301 standard. The bottom line: these gray 30mm x 37mm x 5mm key tags offer straightforward compatibility with many 125 kHz weigand readers and a predictable site code, making them a practical bulk option for systems that accept the same site code and are not iClass based.

Key Features

• Common format: Supplied preformatted to the 26-bit H10301 standard so they can often be used directly with access control systems that accept that format.
• 125 kHz proximity: The 125 kHz RFID frequency means the fobs work with a wide range of legacy contactless readers commonly deployed in commercial and residential sites.
• Compact appearance: At about 30mm x 37mm x 5mm the gray key fobs are small and light, fitting easily on key rings without adding bulk.
• Bulk quantity: The pack of 25 is convenient for property managers or small businesses replacing multiple credentials at once without repeated purchases.
• Reader compatibility: Designed to work with many 26-bit weigand readers including ProxPoint, MiniProx, Prox80 series and similar models that accept ISOProx formats.
• Site code clarity: Fobs ship with a known site code so installers can confirm compatibility before deploying them on existing systems.

Who It's For

This pack is aimed at installers, maintenance teams, and small to medium property managers who run access control systems that already use the 26-bit H10301 format and 125 kHz prox technology. It is ideal when a single site code can be applied across new credentials and the goal is to replace or expand access tags quickly and affordably.

Those who should look elsewhere include sites that require iClass or high-frequency credentials, or systems that enforce a different site code without cross-acceptance. If a system requires encrypted or high-security tokens, these low-frequency prox fobs are not suitable.

Pros & Cons

Pros

• Good value per tag when replacing multiple credentials at once.
• Works out of the box with many 26-bit weigand readers when the site code matches.
• Small, durable form factor that fits on standard key rings.
• Clear product information reduces guesswork for installers about format and frequency.

Cons

• Not compatible with iClass readers and other non-125 kHz systems.
• Some customers report mixed functionality on certain systems, so compatibility is not guaranteed unless the site code and reader model match exactly.

Our Verdict

These 25-pack 26-bit prox key fobs deliver straightforward compatibility and economy for systems already running 125 kHz ISOProx credentials with the same site code. They are a sensible, low-cost choice for facility teams who need many replacements quickly, but buyers should confirm reader model and site code compatibility before ordering to avoid mixed functionality.

Frequently Asked Questions

Will these work with iClass readers?
No. These fobs use 125 kHz prox technology and the 26-bit H10301 format and will not work with iClass readers.

What site code do the fobs use?
The fobs are supplied with site code 98; confirm whether your system accepts that site code or multiple site codes before purchasing.

What information should I provide if they do not work?
Provide your access control system name and version plus the make and model of the card reader so technical support can check compatibility.
