Matrix (2004) alarm issue

This has been happening off and on for the past six months, and it's seem to have gotten worse. Sometimes when I press the button to arm the car it locks the doors, but doesn't beep and arm the alarm. Also sometimes when I have my car armed, and I press the unlock button it unlocks the door, but doesn't give the *beep-beep* and disarm the alarm. So when I open the door the alarm goes off, and I have to try opening and closing the doors, sticking the key in the ignition, repeatedly pressing the unlock button and eventually it disarms. I took it to the dealer, and they reseated a cable, but that didn't correct the issue, and of course it worked perfectly for them. Any suggestions.

***********
The next time the door unlocks but the alarm does not disarm, try inserting
the key in the door and unlocking it manually before opening the door. If
this does not work, try inserting the key in the passenger door (if it has a
passenger side key opening) and see if it works.

I suspect that the door unlock sensor for the security system is not
working.

If the alarm is activated, try inserting the key in the ignition, turning it
to the on position, then off, then back on.
