Note: For all vehicles with a non Ford-approved remote start installed, it
is possible to program all "real" keys as MyKeys™, in which case, you
will need to use your remote start system to reset all MyKeys™ as admin
keys by doing the following:
1. Enter the vehicle, close all doors.
2. Remote start the vehicle using your remote start fob.
3. Follow steps 1-4 in the Clear MyKey™ section.
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 authorized dealer for a Ford-approved remote start system.
When using a Ford-approved remote start system, the default settings
will recognize the remote start system as an additional admin key with
its associated privileges. Owners of vehicles equipped with traditional
keys should program the remote start system as a MyKey™ in addition
to the key that they have already programmed as a MyKey™. To
program the remote start system as MyKey™, do the following:
1. Enter the vehicle and close all doors.
2. Remote start the vehicle using a remote start fob.
3. Follow Steps 1-4 in the Create a MyKey™ section.
Note: For all vehicles, the number of MYKEY(S) PROGRAMMED or
ADMIN KEYS PROGRAMMED that is displayed in the MyKey™ system
status menus will include the remote start system as an additional key in
the total count. See the Check MyKey™ system status section.
Note: For all vehicles with remote start installed, it is possible to
program all "real" keys as MyKeys™, in which case, you will need to use
your remote start system to reset all MyKeys™ as admin keys by doing
the following:
1. Enter the vehicle, close all doors.
2. Remote start the vehicle using your remote start fob.
3. Follow Steps 1-4 in the Clear MyKey™ section.
