FORD 2004 F-550 v.2 - Manual (Page 80)

Anti-scan feature
If the wrong code has been entered 7 times (35 consecutive button
presses), the keypad is disabled for one minute and the keypad lamp will
flash during this time. Note: Pressing 7
• 8 and the 9 • 0 simultaneously
during this one minute period will still lock the vehicle.
The anti-scan feature will turn off after one minute of keypad inactivity.
Unlocking and locking the doors using keyless entry
To unlock the driver’s door, enter the factory set 5-digit code or your
personal code. Each number must be pressed within five seconds of each
other.
To unlock all doors, press the 3
• 4 control within three seconds of
entering a valid keypad code.
To lock all doors, press the 7
• 8 and the 9 • 0 at the same time. You
do not need to enter the keypad code first.
To verify all doors are closed properly, press the 7
• 8 and the 9 • 0
again within three seconds. If the doors are closed, the horn will chirp
once; if any door is ajar, the horn will chirp twice.
Low battery warning
When the battery in the keypad is running low, the remote keypad will
provide you with a warning.
The remote keypad battery has two power management modes:
• Power save mode — In this mode, the keypad light will not function,
but the lock and unlock features will still be active. Note: Because of
the nature of the keypad battery, the power save mode does not
indicate that the battery needs to be changed.
• Alert mode (low battery warning) — In this mode, the keypad
light will not function. After you have entered your factory set or
personal entry code into the keypad, instead of unlocking the driver’s
door, the vehicle will unlock the driver’s door, lock it, then unlock it
again in order to signal that the battery should be changed.
After receiving a low battery warning, replace the battery at the earliest
opportunity in order to ensure proper keypad function.
Replacing the batteries
The keyless entry keypad uses one coin-type three-volt lithium battery
(Service Part Number 3L2W-19G545–A). This replacement battery is only
available through your authorized dealer.
