Can I use a custom config with keys on the MT20 to read customer specific credentials?

Yes, custom configuration with keys can be used if the customer's credentials were encoded using Allegion's standard access control application. 

There are two different types of configuration cards with keys:
1.Standard Access Control Application – This type of configuration card contains custom keys but the same encoded card data that is used on Allegion smart credentials.
2.Custom Access Control Application – This type of configuration card also contains custom keys but the encoded card data and output is customer specific.

Currently, the MT20 is only compatible with configuration cards with keys that use our Standard Access Control Application.  To confirm which restricted custom configurations can be used with the MT20, please contact Product Support.
