22,0023,00 (excl. VAT)

Electronic RFID keys suitable for any system operating at 125kHz (massively used). (The price is for 100 pcs.)

Depending on what system you will use them for, choose one of the two options – “With Engraved Code” or “Without Engraved Code”. The two types of keys are exactly the same in functionality and range, the only difference being whether they have their 10 digit code engraved on top or not. (If you use them with BulKey systems, you dont need the engraved code)

kHz) distinguished by high quality and very good range. As can be seen from the pictures, all RFID chips are the same in appearance, but LESI keys are distinguished by the larger size of the antenna, which significantly increases the range of operation. Information can be printed/engraved on them. Ergonomic and comfortable to wear.

The electronic RFID chip has a 64-bit code. By means of a specially developed anti-scan and with so many code combinations, the system gives extremely high reliability of protection against unlocking by using high-tech computers and systems. An advantage of standard RFID keys is that they are the cheapest electronic keys possible.

RFID keys also have variants with cryptography or with a larger code that CANNOT be copied. You can view them HERE.

Works with Bulkey BKU217, BKU417 and all standard RFID systems! Systems working with this type of electronic keys can use three types of readers – for built-in, panel, hidden installation, depending on the place of application of the locking system. The fact that contactless readers can read the electronic chip code from a distance of 1 cm to 12 cm (typically between 2 and 5 cm) allows them to be hidden by being installed behind non-magnetic barriers such as glass, wood or others.

An advantage of the built-in contactless reader, patented by LESI, is that it can be installed directly in the door or cash register, regardless of the material of which the door is made, and at the same time the reader cannot be stolen.
