It might be a fault with the anti-theft feature. Ford has had several recalls due to this. Web search for safety recall on faulty key-in-ignition chime. I had the same problem with my 1998 Ford Explorer Sport although it started chiming all by itself. On my Exlorer there is a set of 5 wires in a yellow sheath running from the ignition module to a brown connection point/harness in a very uncomfortable position directly under the steering column above the pedals. I unplugged the connection at this point. This stopped the key-in-ignition chiming but I still get the chime alerts for headlights left on, initial chime when the key is turned. The pinging, or ringing chime comes from the multifunction computer located under the dash behind the radio. Hope this help.
Another possibilityIt could also be caused by a stuck door ajar sensor.See "Related Questions" below for much more about dealing with door sensors.
On one of my older Taurus' I simply followed the irritating noise to the source, up around in the neighborhood of the fuseblock.
There was a simple wire connection to pull off and the silence was golden.
Major information: The 90's series of Taurus's all had a weak ignition lock. Once it is worn it is possible to remove the key without the ignition switch being fully locked, when this happens the "key in" chime will sound, just as it does when you leave the key in the ignition. This has NOTHING to do with anything EXCEPT the ignition switch itself and is easily serviced by replacing the lock, a relatively simple procedure.
If the ignition chime will not turn off on a 1994 Ford tempo the switch for the sound is jammed. The steering column with have to be removed to access the switch for the ignition chime.
My 1995 Ford Explorer has also done that occasionally ( although I have removed the ignition key as soon as I open the drivers door , the key in ignition chime starts " going " ) What I do is put the ignition key back in and then remove it again and the chime will stop Give that a try
Find and remove the chime.
There is a small switch inside the steering column lock mechanism. When that switch fails it can cause the door alarm to chime. The chime is supposed to inform you that the key is still in the lock, but when that switch fails it can certainly cause the problem you described.
Do you mean the key in ignition chime?
Head lights on?
The chime can not be disabled or removed.
Pull the key out just a little and the chime will stop. It may be controlledfrom the radio
take the key out of the ignition switch.
The chime is part of the body computer and can not be removed.The chime is part of the body computer and can not be removed.
most likely is a faulty chime switch,or a faulty ignition switch
There is no actual "chime" for the backup warning. The chime is generated by the radio just like the "KEY IN IGNITION" or the "HEADLAMPS ON" chime. The Rear Parking Assist Moudle sends a signal to the BCM which requests the proper chime for the Radio to produce in the speaker(s).
