FAQ

What is a Dormakaba key fob?
A Dormakaba key fob is an RFID credential used in access control systems to unlock doors, gates, or elevators in residential and commercial buildings.

What technology do Dormakaba EV3 fobs use?
The Dormakaba credentials use MIFARE DESFire EV2/EV3 technology. Dormakaba's DESFire AID is f53280. The stored data is encrypted with Dormakaba proprietary encryption. To read the stored data. An AES-based 3-pass mutual authentication is performed (Dormakaba uses DESFire EV2 authentication). The data is then sent encrypted and MACed (Message Authentication Code). The 128-bit AES key is derived from the tag's UID. That means every tag's authentication key is different. Even if you manage to extract the key from your credential, you can't read other credentials. The Dormakaba readers have the master key that can authenticate with all the Dormakaba credentials. To protect the master key. The key diversification occurs on a SAM (Secure Access Module). The SAM is a specialized hardware chip that's used to securely store cryptographic keys and perform safe authentications. The SAM is designed to be impossible to crack if used correctly.

Why do you need a photo of my fob?
Dormakaba produces many different variants with different chip technologies and memory sizes. A photo helps identify the exact model so the correct duplicate can be created.
