Ding alert after removing keys and opening driver side door. Headlights are off.

[Milamber777]

I did locate a single previous post but wanted to be sure this is the same issue, and confirm how to get by until able to get it repaired.

I have a 98 Mountaineer 5.0L. Intermittently starting yesterday when I remove the keys and go to exit the vehicle, it dings as if the headlights are on or the keys are in the ignition. I confirmed that the headlights are off, and the keys are definitely removed.

I confirmed all sorts of oddities such as: all doors and windows are closed tightly, turned the autodimmer to off, properly set in Park, deliberately started then turned off and removed the keys - then locked the wheel. Still, every time I open the driver side door, the persistent dinging alert sounds.

The post http://www.explorerforum.com/forums/showthread.php?t=227619 indicated it is a ignition switch malfunction. A couple of questions (and my apologies for my inexperience):

1) Is there a fuse that might have blown? Doesn't seem to make sense since it starts normally.

2) Is battery drain something to be concerned about? If so, should I disconnect one of the terminals so I can be sure I can get to the shop for replacement if need be? Can someone confirm which terminal, or both, to disconnect?

3) Are there any other possible causes that I should look into? Any suggestions for repair?

4) What would a rough cost of an ignition switch replacement be at a shop?

Thanks in advance to everyone for their help and suggestions.

My ignition swithc is worn that if I fail to turnit to the proper place the key buzzer will keep going. No big deal. you just have to turn the switch a little. Mine has done it for a couple years at least.

IF the problem is the "key in ignition" alert, You can completely disable it if you'd like.
