4 – Encoding Keys
Methods of Encoding
Encoding a key involves electronically writing user-identification information for system
access onto a Fleetkey. There are three methods for encoding: from the KE200 keypad, from
the KE200 data terminal using the “EN KE” command, and from the FleetKey system with the
encoding option (refer to the FleetKey Operation Manual for details on encoding with this
option).
Key Fields
The encoded information on the Fleetkeys is broken down into fields, which appear in a set
order with regard to location and length. The system provides up to 20 characters of variable
identification fields (19 numeric for CFN) that allows you to customize the system to your
particular information requirements. The names and sizes of these variable fields were
specified at the time of your system order. You can have any combination of fields totaling up
to 20 characters (19 for CFN). However, the maximum number of separate fields is eight. You
may also specify which key(s) the various information fields are encoded on in a dual key
application, with one exception. In dual key systems where VEH is used as an ID field, this
field must be encoded on the Vehicle key (key type 2).
This section describes the information fields encoded on the keys. You do not have to use all
the fields. If you choose not to use certain fields, you can zero-fill the fields (where allowed)
when you are encoding the key.
