Service key

The Service key is a passive transponder and acts as a programming key. Using the service key, the cylinder or reader can be shifted to the programming mode. In this mode, programming can be carried out and the captured data can be read, for example, event logs or battery data.

If the original service key is lost, then it can be substituted by a spare service key. Likewise, sub-service keys can also be created.

The product is available for all common transponder technologies of EM/HITAG, LEGIC® and MIFARE®.
