The system is not compatible with
non-Ford aftermarket remote start systems.
Use of these systems may result in vehicle
starting problems and a loss of security
protection.

or a second coded key on the same key
chain may cause vehicle starting problems
if they are too close to the key when starting
your vehicle. Prevent these objects from
touching the coded key while starting your
vehicle. Switch the ignition off, move all
objects on the key chain away from the
coded key and restart your vehicle if a
problem occurs.
