Alarm woes

[Mark Trank]

My previous post on this topic garnered no responses (ask a dumb question?)
so I'll try again with what is hopefully a better-phrased inquiry.  I am
experiencing a frustrating problem with the driver's side door lock/alarm.
When I lock the car on the driver's side, the alarm chirps and arms.
However, when I unlock on the same side, the alarm stays armed, and
immediately goes off when I insert the key in the ignition.  I have to get
out of the car, proceed over to the passenger side, and turn the key until
the alarm stops.

Have any listers experienced a similar problem?  Can you recommend a repair
procedure?  Is it possible to disconnect the alarm without compromising the
door lock system?

Thanks, Mark
