What Are These RFID Key Fobs Used For?
These tags work with any access control system that supports 125KHz TK4100 (also known as EM4100) read-only chips. That covers a wide range of common setups, including:
– Apartment and building entry systems
– Office door access panels
– Car park barriers and gates
– Attendance tracking systems
– Time-and-attendance clocking machines
They’re a practical solution when you need to replace lost fobs, issue extras to new team members, or simply keep spares on hand without ordering one at a time.

Simple, Plug-and-Play Compatibility
Each fob comes pre-programmed with its own unique ID, which is laser-printed directly onto the tag for easy identification and record-keeping. Because the chip is read-only, there’s nothing to configure — you just register the fob’s ID in your existing access control system and you’re good to go.
Important: These are read-only tags. They cannot be written to or reprogrammed. Before purchasing, confirm that your access control reader supports 125KHz TK4100 or EM4100 chips. If your system uses a different chip type or frequency (such as 13.56MHz MIFARE), these fobs won’t be compatible.

Built to Handle Everyday Use
Durable ABS Construction
Each key fob is made from hard-wearing ABS plastic, measuring approximately 43.7 x 30 x 5.3mm — compact enough to sit comfortably on a keyring without adding bulk. They’re waterproof and rated to operate across a wide temperature range (-40°C to 85°C), so they’ll hold up in outdoor entry points, car parks, and other exposed environments.
Reliable Read Performance
– Read speed: 0.2 milliseconds
– Read range: Up to 5cm (standard for proximity access)
– Chip endurance: Rated for up to 100,000 read cycles
That kind of durability means these fobs should last well under normal daily use.

Great Value When You Need Multiples
Buying individual replacement fobs through a building manager or supplier can get expensive quickly. This 20-pack is a straightforward, cost-effective way to keep your access control system running smoothly — whether you’re a property manager, small business owner, or just someone who goes through key fobs faster than expected.
The mixed colour assortment also makes it easy to colour-code fobs for different access levels or user groups, which is a handy little bonus for anyone managing multiple people.
