2002 Ford Focus Doors lock with key fob, but horn does not honk

Check to see if your vehicle honks when you press the "lock" button on your key fob. Press the "lock" button multiple times in a row. Many devices won't beep unless you double-tap the button after locking. If the horn doesn't honk, but the lights flash, your chirp feature is probably disabled.

Use your keyless fob and ignition key to enable the audible chirp. The process varies considerably on different makes and models. You must usually consult your owner's manual, a dealership or the alarm manufacturer for the correct process.

Unlock all doors, foot on brake, all doors closed. Cycle key quickly but carefully on-off appr 10 times until the car honks one time.

Do not turn the key far enough to start the car, just to the 'on' position so the dashboard lights up.

When the horn honks, open and close the driver's door, press any remote button and that's it.

Program another remote? Quickly open and close the driver's door again and push a button on the 2nd remote. That's it.

When you're done, remove the key and the horn should honk 3 times. You're all set.
Sometime it takes more than 10 on-offs to set program mode. Open/close the door, lock/unlock etc, wait 10 minutes, then try again

Replace the battery on the key fob! Also, it may need to be reprogrammed by the Dealer!

You need the dealer on this.

sounds like a charging issue is your battery low

sounds like lock button on key fob is stuck or there maybe radio interference around vehicle making it do that? did it just start doing it? if so maybe a neighbor just hooked up wireless internet? take battery out of key fob and see if it still does it,if still does,talk to neighbors and see if any one installed a new wireless router?also you can find out what mega hertz your system is running get a scanner and program numbers and see if there is any interference!!!Also when you take out battery out of key fob try soaking fob in rubbing alcohol and then let throughly dry then reinstall battery(if unit got wet maybe shorting terminals or sticking)try that may haft to reset alarm when you take out battery of fob!!!! :) Hope This Helps!!!!
