The keyless entry keyfobs (2) will not lock or unlock doors. Even after reprogramming the keyfobs as per owners manual they still don't work. After driving a short distance, I got out and tried to lock the doors--surprise it worked. When I returned to the car I was able to unlock the car. After getting home, I went back out to the car and again NEITHER keyfob would unlock the car. WHAT ISTHE PROBLEM?

Hello Cathy

It does indeed have keyless entry. It needs reprogramming when you get a new remote. Also if you disconnect the battery. Usually a local car alarm fitting shop, or an auto-electrician will do it. Plus of course a Ford dealership.

The keyless entry system consists of the following components:

• driver door module (DDM)
• keyless entry transmitter
• keyless entry keypad

The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, brake 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).

• Battery junction box (BJB) fuses:
  • circuit breaker 7 (20A)
• Central junction box (CJB)
  • 4 (10A)
  • 6 (15A)
  • 8 (25A)
  • 13 (5A)
• Keyless entry keypad switch
• Power door lock actuator
• Luggage compartment release switch
• Luggage compartment release solenoid
• Connectors or connections
• Wiring harness
• If fuse's good have checked for DTC'S - diagnostic trouble codes .
• B1526 Keyless Entry Circuit Short to Ground DDM Go To Pinpoint Test E . B1553 Decklid Release Circuit Short to Battery DDM Go To Pinpoint Test B . B1751 Park/Neutral Switch Circuit Short to Battery DDM Go To Pinpoint Test K . B2425 Remote Keyless Entry Out of Synchronization DDM Go To Pinpoint Test L Need a professional grade scan tool to check fro these codes . Not a code reader for OBD2 codes .

• The doors do not lock/unlock using the remote transmitter

• Remote transmitter not programmed.
• Remote transmitter.
• DDM.

• Go To Pinpoint Test F .

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.

1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.

1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.

1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.

1. To exit program mode, turn the ignition to START or wait 7.5 seconds.

1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

Go to your owners manual It tells you how to do it

The alarm is armed if keyfob is used. So you must use the fob to disarm alarm first. So someone can not unlock and open door without keyfob or alarm will be set off.

TRY THIS REPROGRAMMING PROCEDURE. SWITCH THE IGNITION OFF TO ON 8 TIMES WITHIN 10 SECONDS. DOORS SHOULD LOCK THEN UNLOCK. PRESS ANY BUTTON ON THE FIRST REMOTE TRANSMITTER. DOORS SHOULD LOCK THEN UNLOCK. IF YOU HAVE ANOTHER CAR REMOTE REPROGRAM IT THE SAME WAY. WHEN DONE SWITCH IGNITION SWITCH OFF.

Hi.

To program ( or reprogram ) a keyless entry remote transmitter into the remote keyless entry module, perform the following steps:

1. Turn the key to ON or ACC and short the two terminals of the program connector, a two-pin connector located below the driver's side of the instrument panel at the base of the steering column. All doors should lock and then unlock.
2. Press any button on each keyless entry remote transmitter in turn. All doors should lock and then unlock. If the door locks do not respond, press the button again (up to three times maximum with the same keyless entry remote transmitter). If the door locks still fail to respond, go to Pinpoint Test A.
3. Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to four keyless entry remote transmitters maximum).
4. Turn key off.
5. Remove the short from the program connector. All doors should lock and then unlock.
6. Verify that the keyless entry remote transmitters have been successfully programmed by pressing the LOCK or UNLOCK button on each one, and observing that the system responds by locking and/or unlocking the doors.


I hope this helps you.

Thanks!

Try reprogramming the remotes. Here are the instructions for the procedure. Hope it helps. Cobra!
Programming NOTE: All keyless entry remote transmitters (15K601) must be programmed at the same time.

door pad keyless codes?

in owner manual, enter permanent code and then press "1" and enter personal code, then press "1" again. Then both codes will work.

If you don't have manual, go to Motorcraft.com and click on technical resources and click on your year owner manual.

---------------------------------------------
Each vehicle equipped with a keyless entry keypad is programmed with a five-digit entry code. This code is provided to the customer through a wallet card in the Owner Literature package. In addition, this code is available through a diagnostic tool and is also printed on the vehicle security module label. When entering codes each digit must be entered within five seconds of the previous button press.
Programming/Erasing Personal Code
A unique personal five-digit code can be programmed by following these steps:

1. Enter the factory set five-digit code (the keypad will illuminate when pressed).

1. Press 1/2 within five seconds of Step 1.

1. Enter the unique five-digit code.

The personal code does not substitute for the permanent factory set code. Either code can be used to access the vehicle. In addition, if a second personal code is programmed, it will simply overwrite the previous personal code. To erase a personal code, carry out the following procedure:

1. Enter factory set five-digit code.

1. Press 1/2 within five seconds of Step 1.

1. Press 7/8 and 9/0 at the same time within five seconds of Step 2.

The system will now only respond to the factory set code.
Anti-Scan Feature
To provide added security, the keyless entry pad is disabled for one minute after 35 button presses without a valid entry code being entered. The keypad will flash during this one-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-Scan will be turned off after any of the following events:

• one minute of keypad inactivity
• the keyless entry remote transmitter UNLOCK button is pressed
• the ignition is turned to the ON position.

Unlocking the Doors with the Keyless Entry Keypad System
To unlock the driver door, enter either the factory set code or the personal code (each digit must be pressed within five seconds of the prior digit). The interior lamps will illuminate.
To unlock all doors, enter either the factory set code or the personal code (driver door unlocks) and press the 3/4 control within five seconds.
Locking the Doors with the Keyless Entry Keypad System
It is not necessary to enter the factory set or personal code prior to locking all doors. To lock all doors, press the 7/8 and 9/0 controls at the same time.
Inspection and Verification

1. Verify the customer concern by operating the system.

1. Visually inspect for obvious signs of mechanical or electrical damage.
