FORD 2013 F-550 v.3 - Manual (Page 71)

CHECKING MYKEY SYSTEM STATUS
You can find information about your programmed MyKeys by using the
information display.
MYKEY DISTANCE
Tracks the distance when drivers use a MyKey. The only way to delete
the accumulated distance is by using an admin key to clear your MyKey.
If the distance does not accumulate as expected, then the intended user
is not using the MyKey, or an admin key user recently cleared and then
recreated a MyKey.
NUMBER OF MYKEY(S)
Indicates the number of MyKeys programmed to your vehicle. Use this
feature to detect how many MyKeys you have for your vehicle and
determine when a MyKey has been deleted.
NUMBER OF ADMIN KEY(S)
Indicates how many admin keys are programmed to your vehicle. Use
this feature to determine how many unrestricted keys you have for your
vehicle, and detect if an additional MyKey has been programmed.
USING MYKEY WITH REMOTE START SYSTEMS
MyKey is not compatible with non-Ford-approved aftermarket remote
start systems. If you choose to install a remote start system, please see
your Ford authorized dealer for a Ford-approved remote start system.
