125kHz RFID Key Fob Pack

This pack contains ten blue key fobs operating at 125kHz for proximity access control systems. Each fob comes pre-programmed with a unique 10-digit ID number engraved on the casing. They are designed for unencrypted 125kHz systems and are compatible with universal tags such as EM4100 and EM4102. The ABS plastic casing measures approximately 1.4 by 1.1 by 0.2 inches.

Check System Frequency Before Ordering

Verify that your existing access control system uses unencrypted 125kHz frequency before purchasing. These fobs are incompatible with 13.56MHz systems and encrypted tag formats including HID, Indala, Cobra, APCiK, Paradox, Radio, Honeywell, Kaba and Isonas. You cannot re-program the fobs; they are readable and rewritable only in the sense that the system reads the fixed ID. Buyers needing a different frequency or encrypted credentials must source alternative tags.

ABS Casing and Daily Handling

The blue ABS plastic casing provides a lightweight token that withstands operating temperatures from -25 to +75 degrees Celsius. The fob reads at distances up to 10 cm from the reader. With a wiping life of 100,000 cycles and data retention of 10 years, the tag suits daily entry use. The compact size allows easy attachment to a key ring or lanyard for constant access.

Questions about this item

What comes in the pack and is any extra hardware needed?

The pack contains ten blue ABS key fobs, each pre-programmed with a unique 10-digit ID engraved on the casing. No additional hardware is included; you only need a compatible 125 kHz reader.

How do I know these 125 kHz fobs are the right version for my system?

They work with unencrypted 125 kHz systems and EM4100 or EM4102 chips. They will not work with 13.56 MHz readers or encrypted formats such as HID, Indala or Honeywell.

What does the 0-10 cm working distance mean at the door?

The fob must be held within about 0-10 cm of the reader, so you tap it close to the lock rather than waving it from a distance.
