97 buick door locking system

[gerwi]

This 97 Buick Lesabre Limited has a central door locking problem. When the doors are locked, the alarm system is armed. For no apparent reason, the alarm will sound. Is there something to look for?

I'd look for a lazy door latch switch or solenoid. Check all four doors after you lock them with the master switch. Can you open one of them? Is one only half-locked? After 9 years, those springs and solenoids can get worn or dirty. This might be triggering the alarm that a door is 'open'.
