Oldsmobile/Buick Repair: 1998 olds cutlass 3.1 L, theft deterrent system, olds cutlass

Question
I have a 1998 olds cutlass 3.1 motor
Sometimes when I go to start my car the ant-theft light blinks on the dash.  I then have to wait up 10 minutes for it to quit so I can start my car.  While driving the
will sometimes flash.  This does not occur every time. once i get it started I am good for a couple of starts before it blinks again. What do I need to do to fix the
problem. Thanks

Answer
Hi
I would suspect EITHER the Passlock sensor/key switch, OR the BCM (Body Control Module).
My best advise would to be to take it to a good shop, and have the theft deterrent system codes scanned and properly diagnosed, to avoid changing good parts.
I Hope this helps.
Good Luck
