When locking and unlocking doors, the horn will not chirp

Sounds like a vehicle security module problem , but , without doing some testing that would be just a guess .
Checking for DTC'S - diagnostic trouble codes first ,then checking power an grounds to the module . Viewing wiring diagrams an testing electrical circuits for the locks too see if anything is wrong , missing power or grounds etc... Do you know what a wiring diagram is ? How to use a DVOM - digital volt ohm meter to test electrical circuits ? Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. year , make , model an engine size. Under system click on body & accessories ,then under subsystem click on power locks . Click the search button then the blue link . If not familiar with automotive electronics your best bet mite be to take it to a qualified repair shop.

Power Lock
The power lock/unlock feature requests all of the vehicle doors, including the liftgate, be locked or unlocked upon a customer request from any interior door lock switch in the vehicle. The power door locking system functions independently of ignition status or vehicle speed. When the vehicle security module receives an unlock/lock command from any door lock control switch, the vehicle security module will activate relays internal to the module to supply the correct power and grounds for the door lock actuators.

Power Unlock Inhibit
NOTE: This feature is not enabled when the vehicle is delivered to the customer. If the customer requests this feature the module can be configured to enable this feature.
With the key in OFF, 20 seconds after electrically locked (remote transmitter, keypad, door lock control switch locked with door ajar) and all doors are closed, the door unlock switch will be inhibited if this feature is enabled. (The lock function will still operate.)
Deactivating/Activating Power Door Unlock Switch Inhibit
NOTE: The power door unlock switch inhibit feature needs to be enabled to perform this procedure.
This is customer configurable. Steps one through three must be completed within 30 seconds.

1. Turn the key to ON, then press UNLOCK three times.

1. Turn the key to OFF, then press UNLOCK three times.

1. Turn the key to ON, within five seconds press LOCK two times.

The user should receive two horn chirps to indicate the system has been disabled or two chirps followed by a horn honk to indicate the system has been enabled.
Pressing LOCK two times again will toggle the door lock control switch inhibit feature state.
Turn the key to OFF to exit programming mode.
This feature can also be enabled/disabled using a diagnostic tool.
Auto-lock Enable/Disable - Using the Ignition Switch
Another way to turn the auto-lock feature off/on is by following this series of steps:

1. Close all doors.

1. Confirm that the key is in the OFF position.

1. Turn the key from OFF to ON.

1. NOTE: Steps 4 through 8 must be carried out within 30 seconds. Press UNLOCK three times.

1. Turn the key from ON to OFF.

1. Press UNLOCK three times.

1. Turn the key from OFF to ON.

1. Verify that the horn chirps. This indicates the enable/disable mode and now is ready to accept program changes.

1. Press UNLOCK once to command the vehicle security module to toggle the auto-lock/relock feature OFF.

1. Press LOCK once to enter the command.

1. Verify that the horn chirps one time. There should only be one chirp indicating that the auto-lock/relock feature has been disabled. If one chirp is heard followed by a longer sound of the horn, the auto-lock/relock feature has just been enabled. Return to Step 10.

1. Turn the key to the OFF position to exit the enable/disable mode.

1. Exit the vehicle and verify that the horn chirps once to indicate that a feature has been changed and that auto-lock/relock has been disabled.

tis a process so here goes..... Central Security Module (CSM) enable/disable mode allows autolock feature to be turned on or off. To enter enable/disable mode, close all doors. Ensure ignition switch is in LOCK position. Perform the following steps within 30 seconds:

Turn ignition switch from LOCK to RUN position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from RUN to OFF position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from LOCK to RUN position.

CSM module should chirp horn indicating CSM module is in enable/disable mode and ready to accept program changes.

Press power door lock switch UNLOCK button once to command CSM module to toggle autolock feature on or off. Press power door lock switch LOCK button once to enable/disable autolock feature. CSM module will chirp one time to indicate autolock has been disabled.

CSM module will chirp once, followed by a longer chirp to indicate autolock feature has been enabled. Press power door lock switch UNLOCK button once, then turn ignition switch to OFF position to exit enable/disable mode. CSM module should chirp once to verify a feature change. Best to you.

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.

Your Focus may be equipped with the autolock feature. Try this:

To deactivate/reactivate the autolock feature using the power door unlock control

My chevy doesn't chirp on the first press of the lock button, it just locks. If you press it again, then it chirps. To be honest, I like the fact that it doesn't chirp first - that just draws attention to the fact that you left your vehicle.

To turn off the auto locks 1 turn the key on 2 press the unlock button 3 times, 3 turn the key from on to off, 4 press the unlock button 3 times, 5 turn the key back to on and the horn will chirp, 6 press the unlock button, then the lock button. the horn will chirp once if the auto locks are deactivated, or twice one short and one long chirp if activated. 7 turn the key off and the horn will chirp once to confirm exiting the system

It sounds like it has been deactivated so we are going to reactivate the auto lock.

The numbers I will be saying will have to do with getting this to work so:
you will need to put the key in to the ignition switch.

1= is back to listen to the radio
2= is to get key out
3= is just before you start
4= is for starting your car

When we do this 1 and 4 will not be used
Do this and we will hope that it works like it should:

1: Turn the ignition with you key up to on( don't start)

2: Press the power door lock control 3 times

3: now turn the key back once (to off position)

4: Press the power door unlock control 3 times

5: ok turn the ignition back up 1 time. (The horn should chirp)

6: Then press the unlock control, then press the lock control, again (horn will chirp 1's) If auto lock
was activated.

7: Turn the ignition back 1's, Then the horn should chirp once to confirm the procedure was completed.
