How do I disarm the factory alarm in my car?

Try this,Put key in and turn to the on position,then replace battery cable,turn iginton off then back on,if this doe,s not work ,your ecm doe,s not reaconize the key,and you will have to have a dealer fix this issue.

Ok I will try that and get back to you. I do know that when I first got the keys it took about an hour for car to recognize them and want to start but this problem with the alarm came after I reset the timing alignment; they were working just fine before.
