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.
Vehicles equipped with traditional keys:
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 a 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 1-3 in the Create a MyKey section.
Vehicles equipped with an intelligent access key (push button start)
• It is not possible to program the remote start system as a MyKey on
vehicles equipped with intelligent access key (push button start).
Therefore, you should treat the remote start fob as you would any
other admin key. When the vehicle is started using remote start, the
system will stall the engine when you either enter the vehicle or shift
the vehicle into gear. Prior to the engine stall, the vehicle will have
administrative privileges. When you restart the engine, the vehicle will
identify the user as an admin or MyKey driver depending on the
settings of the actual key used to start the vehicle.
Note: For all vehicles, the number of MYKEY(S) or ADMIN KEY(S) that
is displayed in the MyKey vehicle information 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 1-3 in the Clear MyKey section.
