Locks and Security
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 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.
Vehicles equipped with an Intelligent Access Key (push button
start)
• It is not possible to program the remote start system as 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) 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 original vehicle 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 Disable MyKey™ section.
