The key switch usually breaks or wears out and makes contact. It is on the lock cylinder. This would cause the chime to not come on, or stay on. Sounds like the switch is bad.

1997 F-150/250 Warning Chime, Key-In-Ignition The key-in-ignition chime warns that the key is still in the ignition when the driver's door is ajar. The key-in-ignition warning chime will sound when:

• GEM: Driver door is ajar, the ignition switch is in the OFF/LOCK or ACC position and the keys are in the ignition.
• CTM: Driver door is ajar, the ignition switch is in the OFF/LOCK, ACC or RUN position and the keys are in the ignition.

The key-in-ignition warning chime will stop sounding when:

• Driver door is closed.
• Key is removed from the ignition.
• GEM: Ignition switch is switched to the RUN position.

The key-in-ignition warning chime inputs are:

• Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
• Ignition switch ACC position (battery potential on RUN/ACC input only).
• Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).
• LH door ajar switch (open circuit with door closed, grounded with door ajar).

This is a pic for a 98, could not find one for 97 which may be the older style which is more prone to break.

I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
