2003 FORD MUSTANG key battery

Replacement of the battery willnotcause the
remote transmitter to become deprogrammed from
your vehicle. The remote transmitter should operate
normally after battery replacement.
Replacing lost transmitters
•Take all your
vehicle’s transmitters
to your dealer if
service is required.
•If you purchase
additional
transmitters (up to
four may be
programmed into memory), perform the following
procedure.
To reprogram the transmitters yourself, place the
key in the ignition and turn from LOCK to OFF and
cycle between OFF and ON eight times in rapid
succession (within 10 seconds) ending in ON. After
doors lock/unlock, press any control on all
transmitters (up to four). With each control press of
the transmitters, the door should cycle (lock/unlock)
to confirm programming. When completed, turn the
ignition to OFF. The door locks should cycle
(lock/unlock) one last time to confirm completion of
programming.
All transmittersmustbe programmed at the same
time.
Illuminated entry
The interior lamps illuminate when the remote entry
system is used to unlock the door(s) or sound the
personal alarm.
The system automatically turns off after 25 seconds
or when the ignition is turned to the START/RUN or
ACC position. The dome lamp control (if equipped)
mustnotbe set to the OFF position for the
illuminated entry system to operate.

The inside lights will not turn off if:
•they have been turned on with the dimmer
control, or
•any door is open.
The battery saver will shut off the interior lamps 30
minutes after the ignition has been turned to the
OFF position, 10 minutes after if the door is left
open, and 30 minutes after if the trunk is left open
or the dome lamp control is left on.
SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine
immobilization system. This system is designed to
prevent the engine from being started unless a
coded key programmed to your vehicleis used.
The SecuriLock
passive anti-theft 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.
THEFT INDICATOR
The theft indicator is the flashing red indicator
located on top of the instrument panel.
•When the ignition is in the OFF position, the
indicator will flash once every 2 seconds to
indicate the SecuriLock
system is functioning as
a theft deterrent.
•When the ignition is in the ON position, the
indicator will glow for 3 seconds to indicate
normal system functionality.
If a problem occurs with the SecuriLock
system,
the indicator will flash rapidly or glow steadily when
the ignition is in the ON position. If this occurs, the
vehicle should be taken to an authorized dealer for
service.
