- Quantity: Package contains 1pcs handheld 125KHz RFID writer and 10 pcs T5577 blue keyfobs, the card reader is in a mini handheld housing for easy portability. Note: The 10pcs T5577 keyfobs included in the package are the default blank command product, without pre-programmed card numbers, you cannot directly add them to RFID locks or use a card reader to read them. Before using, please write data(card numbers) into them by a 125kHz RFID card writer first.
- Application: 125KHz handheld duplicator support writing T5577, EM4305, CET5200 and all the T5577, EM4305 compatible cards, can be duplicated 20,000 times, the keychains and cards reading and writing distance of 2.5 to 6cm. Note: 125 KHz only: This handheld copier/duplicator is designed exclusively for duplicating 125 KHz low-frequency cards, such as thin ID cards, thick ID cards, and key fob cards. It is not compatible with NFC, 13.56 MHz high-frequency cards (IC cards, CPU cards, encrypted access control cards), 960 MHz cards, or cards operating at other frequencies, nor is it compatible with encrypted cards.
- Purchase Notice: Ensure that the 125KHz handheld RFID writer supports the type of keyfobs (cards) and protocol you are using, such as the common protocols EM4100、T5577、EM4305, etc. to avoid non recognition, The machine can replicate parking cards, access cards. The 125KHz handheld RFID writer needs to be fitted with 2 x 1.5V AAA batteries before use, note: batteries need to be purchased separately.
- Chip: Our products are equipped with an advanced chip with higher operability, stability and reliability, This T5577 chip is responsible for all core functions to ensure the accuracy of data reading and writing.
- Important note for customers: Our standard 125kHz copier works reliably with EM4100 and some basic HID/AWID cards (typically 26‑bit open format). However, many HID and AWID cards use proprietary encoding, longer bit lengths (37‑bit, 44‑bit, etc.), or encryption (e.g. Corporate 1000), these cards cannot be cloned by any generic low‑cost writer. If your card fails to copy, it does not mean the copier is defective – it means your card has advanced security features that require specialized equipment. Please check your card’s format or consult us for compatibility.

Great product!!!
Size: 10 keyfobs
This product works great. But being in the heat during shipment caused the glue on the sticker covering the lights to melt, allowing the sticker to slide down the unit. I easily put it back where it belongs now everything is fine.

Save your money- JUNK
Size: 10 keyfobs
Terrible. Have never seen a more cheaply made electronic device than this. Absolute junk. Did not work at all!

I had a great experience with this product
Size: 10 keyfobs
It worked flawlessly. I programmed all ten fobs in less than a minute. All of them work exactly like the original. I took a wild guess that this was the correct frequency for the fob I wanted to duplicate but I accidentally guess correctly.
