Keyless Entry System Description and Operation - Active
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock/unlock a door or open the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message. A low transmitter battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas, such as gas stations that use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following features:
• Door lock/unlock
• Rear compartment lid release
• Illuminated entry lamps
• Panic alarm/Vehicle locator
• Remote vehicle start

Location of Keyless Code on Computer Module of Ford F250 Superduty ( 2009 )

Finding this code seems to be a common problem, so, here is a better answer to save you the time I spent locating the sticker on the computer module that shows the keyless entry code.

One owners from 2008 F150 XLT Superduty tell me and I suspect the location for a F150 would be very near same location as on a F250

The computer module is mounted high on the firewall approximately behind the a/c fan speed control knob. Here is how to find it / get to it:

1. Remove the large cover under the steering column that covers the fuse block. You'll need to reach in under the dash, with your left arm, to the right of the steering column and left of center to move stuff to get a clear view.

2. Open the storage pocket door on the lower edge of the dash (right of the steering column) and squeeze the back side of the storage pocket to allow the stops to pass to the front. This will allow the opening to be clear to see the computer module up in the dash. Shine your flash light through this opening.

3. Move the first piece of white insulation to the side to see the firewall. Look up through the pocket door, moving the wiring harnesses aside if necessary. You'll find a second white insulation wrapped snugly across the computer module. When you push the insulation up to see the flat surface, you see the 5 digit number printed up-side-down in black on a white sticker. This is your keyless entry code.

Instructions for Programming Keyless Entry Code (from the 2008 Owner's Manual)

KEYLESS ENTRY SYSTEM (IF EQUIPPED)
You can use the keyless entry keypad to lock or unlock the doors without using a key.

The keypad can be operated with the factory set 5-digit entry code; this code is located on the owner's wallet card in the glove box, is marked on the computer module, and is available from your authorized dealer. You can also create your own 5-digit personal entry code.

When pressing the controls on the keypad, press the middle of the controls to ensure a good activation.

Programming a personal entry code
To create your own personal entry code:
1. Enter the factory set code. The driver door will unlock.

2. Within five seconds press the 1 • 2 on the keypad.

3. Enter your personal 5-digit code. Each number must be entered within five seconds of each other.

4. The doors will lock then unlock to confirm that your personal keycode has been programmed into the module.

Tips:
• Do not set a code that uses five of the same number.
• Do not use five numbers in sequential order.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

How to find the Security Keyless Keypad Code on the 1995-2001 Ford Explorer or Mountaineer and how to use the Keypad functions. The factory code is also printed on a label which is installed on the Remote Anti-theft Personality (RAP) Module. This is the module that controls the keyless entry system. It is located in the left rear quarter behind the removable panel (see photo). You will need to turn the two thumb screws counter clockwise and take the plastic panel off to be able to see the unit. A flashlight may be helpful in seeing the code. You are looking for the module and the 5 digit code on it like the one shown below.




Now that you’ve got the code I’ll tell you how to use the Keyless entry and set-up your own code.Make sure when pressing the controls on the keyless entry keypad you press the middle of the buttons to ensure good contact with the controls.

The driver door module (DDM) is connected on the standard corporate protocol (SCP) communication network. The DDM controls many functions including power windows, power door locks and remote keyless entry. The DDM also communicates with the driver seat module (DSM) to control the power mirror and seat memory functions.
Do you know anything about automotive electronic control modules ?
The driver door module (DDM) receives inputs from the digital transmission range (DTR) sensor, ignition switch, seat switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
Best thing to do would be to have a factory scan tool hooked up to check for DTC'S diagnostic trouble codes . That should be the first step if it's not programming the code.
