Do you have 125 kHz access control system and are you looking for a handy RFID transponder with programmable 125 kHz chips for unlocking doors or other identification purposes?

We offer high quality RFID key fobs with the very commonly used programmable chip T5577.

The T5577 key fobs are available in multiple colors (blue, gray, black, green, red, orange, and yellow) and have a popular tear-shaped housing measuring 40 x 32 x 4.5 mm.

The Atmel Temic T5577 key fobs are often purchased by companies and individuals who have a device for programming or cloning 125 kHz read-only chips.

The device reads the 125 kHz read-only transponder and then clones the card ID number onto the new T5577 key fob. When the T5577 key fob is encoded, it acts as a normal 125 kHz read-only chip (like EM4200 or TK4100).

For orders above the 100 pcs., we can do various customization services like printing company logos, serial numbers, or other personalization.

INFO

T5577 key fobs are basically programmable 125 kHz transponders in the form of a keychain and are very convenient to carry around. They can unlock the doors, register working time, or can be used to identify users in various other RFID applications. 

It is not a secret that 125 kHz read-only RFID chips can be cloned with inexpensive and accessible equipment. Several key-makers (in shopping malls, etc.) can duplicate in addition to your regular keys made from metal also your digital key stored on a RFID card or key fob. Banking cards and other secure RFID cards have their security on another level, which is why you cannot use chips T5577 to duplicate banking cards.

Atmel Temic cards T5577 contain a T5577 chip, and its basic component is the Atmel® ATA5577M1330C IDIC® chip that operates on a frequency of 125 kHz and has a programmable memory.

The T5577 chip is the latest version of the T55xx chip and is compatible with the previous versions, the T5557 and T5566.

The T5577 is used for several applications. It is quite common in older hotel systems where the room management system generates a temporary key and it stores it on the card, and is also used in amusement parks, wellness centers, etc. Lately, the chip has become very popular for cloning the ID from other 125 kHz transponders. 

When the T5577 chip is programmed, it stores the cloned ID number and works like the original chips EM4200, EM4100, or TK4100.

The T5577 chip gives multiple opportunities to users and facilitates the work of property managers as well. If a user has a key on a card, it can copy it to a key fob or a sticker. The property manager can issue multiple key cards with a same key (for example for multiple family members), and if he uses offline standalone access control systems he does not have to go physically to the property.

The T5577 key fob housing have a very common tear shape, made from plastic material (ABS) measuring 40 x 32 x 4.5 mm. They also contain a ring with which it can be attached to the keys or other accessory. The key fobs are available in multiple colors (blue, gray, black, green, red, orange, and yellow). 

By default, they do not contain the numeration or other printed elements, but if you need customization, please let us know and we will send you an offer.

Options for customization (for pricing please send an inquiry)

Beside the key fobs from stock, you can order customized key fobs with a housing in different color or shape, we can print on key fobs your company logo, serial number, or chip ID code. 

Reading test for RFID key fobs with 125 kHz programmable T5577 chip

We tested the programmed T5577 key fobs with different kinds of readers and measured the reading distances. This is not an official test, but was made to inform you what reading distances you may expect with your application.
 
RFID Reader Reading distance
Promag PCR-330A-00  4 cm
Syris RD200-LF 3,5 cm
R80D 3 cm

The reading distance between the key fob and the reader is affected by many different factors, like the size of the antennas and quality of the chips, the interferences of metal, and electromagnetic signals, etc.
