While importing a Medeco XT codebook, you see an "Existing credential" error message in Config Tool and Key Programmer.
Cause
This issue occurs when Security Center already
has a credential that uses the Raw 256 bit credential format, and which contains the same
value as one of your Medeco XT keys.
Medeco XT keys use the Raw 256 bit format. Because this format
can contain any data, there is a small chance that a specific key's value might conflict with
a credential from another unified access control system that also uses the Raw 256 bit
format.
Solution
- Delete the credential that is causing a conflict.
- If that fails to resolve the situation, contact Genetecâ„¢ technical support for a solution specific to your deployment.
