Door locks set off alarm on 1994 Acura Vigor

The front door locks will set off the car alarm when unlocking the door with the key. this tends to happen more often in the winter but has now become almost a constant irritation.

Asked by for the 1994 Acura Vigor
Is it a factory alarm or aftermarket? If its aftermarket perhaps disconnect it. If factory fit would need to check the door solenoid and locks to see if one is shorting out (water/moisture could cause a short).
Factory alarm. Had this problem with my previous '92 model. Thanks a lot.
