Keyless Entry
All F150 and SuperCrew models built after 10/2/2000 will be equipped with the central security module.

The keyless entry system consists of the following components:
^ keyless entry remote transmitter
^ remote anti-theft personality (RAP) module (vehicles built before 10/2/2000)
^ central security module (vehicles built after 10/2/2000)

^ all unlock relay (vehicles built before 10/2/2000)
^ all lock relay (vehicles built before 10/2/2000)
^ keyless entry keypad.

The keyless entry remote transmitter initiates the following electronic door lock system functions:
^ unlocks the driver door
^ unlocks all doors
^ locks all doors
^ enables the panic alarm
^ issues the interior lamps on (when unlocking) and off (when locking).
^ sounds the horn once when LOCK on keyless entry remote transmitter is pressed twice, and doors are closed.
^ sounds the horn twice when LOCK on the keyless entry remote transmitter is pressed twice, and any door or the liftgate window is ajar.
^ allows up to four keyless entry remote transmitters to be programmed.

NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.

The keyless entry remote transmitters are reprogrammable and must be set at the same time.

To confirm that the doors have been locked and that the anti-theft system has armed, press the LOCK button again, within five seconds of the first press. The horn will sound once if the doors have locked and all doors are closed.

To activate the panic alarm:
^ Press the red PANIC button on the keyless entry remote transmitter. The horn will sound and the parking lamps will flash for a maximum of 2 minutes and 45 seconds.

To deactivate the panic alarm:
^ Press the red PANIC button again on the keyless entry remote transmitter.
^ Turn the ignition switch to RUN/ACC.

The keyless entry keypad can be used to unlock the driver door or lock and unlock all the doors and the liftgate, if equipped. It also lights the keypad lamp, allows one user code to be programmed and issues illuminated entry on/off requests to the GEM when locking and unlocking.

The system (permanent) entry code is located on the owner's wallet card in the glove box; it is also electronically accessible by using a diagnostic tool and is on the receiver assembly housing.

The receiver assembly is programmed at the factory with a five-digit entry code. A new receiver assembly includes a new owner's code card.

To turn on the interior lamps and light all illuminated components, press any button on the keyless entry keypad.

To unlock the driver door, enter the permanent factory code or enter the owner's alternate code. To unlock the passenger door(s) and liftgate, press the 3/4 button within five seconds of unlocking the driver door.

To lock all doors, press the 7/8 and 9/0 buttons at the same time. (It is not necessary to enter the key code first.) This will turn off the courtesy lamps.

NOTE: The doors will not lock if the vehicle is started in neutral and passed into any forward gear.

If the autolock feature is enabled, the autolock feature will activate when the ignition switch is in the RUN/ACC position, the shift control selector is passed into or through the reverse (R) position and all doors, liftgate and liftgate window are closed when the driver releases the brake pedal.

After the initial lock, all doors will automatically relock when any door is opened and then closed followed by the release of the brake pedal. However, the doors will not relock if the ignition switch is in the OFF position.

NOTE: The door ajar state will be monitored continuously for 500 ms after locking has occurred. If a door is opened again within 500 ms, the driver door will unlock.

The door may not automatically lock if the vehicle is shifted quickly into gear after starting the engine.

Autolock Enable/Disable - Using the Keypad
A manual enable/disable mode allows the autolock feature to be turned off and on.

To enable or disable autolock using the keyless entry keypad:
1. Enter the five-digit permanent entry code into the keyless entry keypad.
2. Within five seconds of entering the code, press and hold the 7/8 button on the keypad.
3. Within five seconds of Step 2, and while holding the 7/8 button, press the 3/4 button on the keypad and release it.
4. Within five seconds of Step 3, release the 7/8 button on the keypad.

If the autolock is disabled, the horn will chirp once. If the autolock feature is enabled, the horn will chirp once shortly and then sound a second time with a longer sound of the horn once the above sequence is completed.

Autolock Enable/Disable - Using the Ignition Switch
Another way to turn the autolock off/on is by following this series of steps:
1. Close all doors.
2. Confirm that the ignition switch is in the OFF position.
3. Turn the ignition switch from OFF to RUN.

NOTE: Steps 4 through 8 must be performed within 30 seconds.

4. Press the power door lock UNLOCK button three times.
5. Turn the ignition switch from RUN to OFF.
6. Press the power door lock UNLOCK button three times.
7. Turn the ignition switch from OFF to RUN.
8. Verify that the horn chirps. This indicates the enable/disable mode and now is ready to accept program changes.
9. Press the power door lock UNLOCK button one time to command the module to toggle the autolock/relock feature OFF.
10. Press the power door lock LOCK button once to enter the command.
11. Verify that the horn chirps one time. There should only be one chirp indicating that autolock/relock feature has been disabled. If one chirp is heard, followed by a longer sound of the horn, the autolock/relock feature has just been enabled. Return to Step 10.
12. Turn the ignition switch to the OFF position to exit the enable/disable mode.
13. Exit the vehicle and verify that the horn chirps once to indicate that a feature has been changed and that autolock/relock has been disabled.
