Remote locking system is erratic

When Horn chirp is enabled, the vehicle horn will chirp on locking and unlocking the vehicle, to enable or disable the horn chirp:

1. Turn headlight switch "OFF"

2. Cycle the ignition switch from "LOCK" to "ON" three times (within 5 seconds) leaving it "ON"

3. The vehicle security indicator will illuminate continuously for 5 seconds

4. During the time the indicator is illuminated, operate the horn(for 1 second). The turn signals will flash once to confirm successful programming.

5. Turn ignition switch to "LOCK" and test system with the remote controls.

To disable horn chirp, repeat the procedure for enabling.

The user manual actually declares customizations of the smartkey must be done by the dealers using special equipment. However, the above procedure works on a variety of years and models. And I see no where in the user manual that refers to the horn and door lock even being a customizable setting.

The RKE is controlled by the SJB - smart junction box ! Fords BCM - body control module .
Principles of Operation
Power Locks
The SJB controls the power lock/unlock feature of all of the vehicle doors, including the liftgate, to lock or unlock based on the input received from the door lock control switch, the keyless entry keypad or the remote keyless entry (RKE) transmitter. Power locking and unlocking of the doors function independently of the key position, vehicle speed or transmission position. The smart junction box (SJB) activates internal relays to supply the correct voltage and grounds for the door lock actuators.

Your best bet would be to take to ford dealer or some other qualified repair shop .
Remote Keyless Entry (RKE) Transmitter Lock/Unlock Control - Unlock
The RKE transmitter feature provides lock/unlock functions independently of key position, vehicle speed, or transmission position. The RKE transmitter feature provides a 2-step process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE control feature requests the SJB to unlock the driver door only. If another unlock request is received within 3 seconds of the first, the RKE transmitter feature requests the SJB to unlock all the doors. This feature can be changed to global unlock, so that all the doors unlock on the first press of the unlock button. To toggle between the 2-step unlock and the global unlock press the lock and the unlock button on the RKE transmitter at the same time and hold the buttons for 4 seconds. The turn signal lamps flash to confirm that the feature has been toggled.
Remote Keyless Entry (RKE) Transmitter Lock/Unlock Control - Lock
The RKE transmitter feature requests that all the doors be locked when the lock button is pressed. On any press of the lock button with all doors closed, the SJB provides 1 flash of the parking lamps. If any door is ajar, no flash occurs. As soon as the last door is closed, the SJB provides the flash of the parking lamps. If 2 presses of the lock button are received within 3 seconds, the horn chirps once, and the parking lamps flash twice to indicate that all the doors are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature requests the SJB chirp the horn twice without flashing the parking lamps to indicate it locked all the doors but 1 or more doors are ajar. When the key is in the ON or START position, the parking lamp flashes and horn chirp confirmations do not occur.

All locks not working ?????

• The doors do not lock/unlock using the remote keyless entry (RKE) transmitter

• RKE transmitter battery
• RKE transmitter
• RKE transmitter programming
• Aftermarket system
• SJB

• Go To Pinpoint Test H .

if this is a factory lock security system you can contact dealer for instruction sheet to re-program your remote or have them do that for you if vehicle is under warranty. if not you can go online and find the procedure for your make,model and year of vehicle. sounds like the remote's battery is need of replacing or the remote needs to be re-programmed

Horn will sound only after keyless entry system has checked all doors and sensors are in locked condition,
including all doors, hood , truck and other locks. I have copied the sensor locations for you and circuit diagram
for keyless/burglar system. Hope this will help.

holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
Done programming? remove the key from the ignition and the horn will honk 3 times.
DELETE old codes? Reprogram 4 times, it will overwrite old codes.
Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
Disarm the system: push unlock for 2 seconds
Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!

Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected

. Seems like the system is not being diarmed. If it wont disarm with remote or by the door klock key, try this. Don't use the power door lock button to lock the car. Lock it MANUALLY till its repaired

Make sure your hood is shut. I just got my 2002 Honda Odyssey back from the dealer today (90,000 mile check-up - I love my van and will drive it until it dies!) and when I went to lock the van with my remote transmitter, the lights didn't flash and the horn didn't sound. I open and closed all the doors and tailgate and I could hear that the doors were locked, but the security system wasn't working and that is why the lights didn't blink or the horn didn't sound. I walked up to the front of the van to check the hood to make sure it was closed (there isn't an indicator light for an open hood, only open doors) and the hood wasn't shut completely. Once I opened the hood and let it drop to securely shut, I hit the door lock button on the remote and everything worked like a charm! Hope this helps others in this predicament.
