Problem with factory alarm on a '03

[eks]

Need some help with the factory alarm on a '03 Corolla S. Somehow maybe I push buttons on the remote while it's in my pocket and then the alarm does not disarm even when I push the unlock button on the remote. The horn beeps 2 times saying the alarm is disarmed, but the light inside still blinks, as if it's still armed. Well I go to open the door, and the alarm goes off.

I had to call the alarm company to get them to help me to turn the alarm off. But they only helped me disarm the alarm for good, until I can get it to the dealer. They won't tell me how to reset the alarm.

This problem has happened 3 times now. The 1st two times the dealer fixed it no problem. But now they want to charge for it because a rep for the alarm company isn't there anymore because of the economy.

They take about 10 minutes to do whatever it is that they do and it's fixed. Anyone know how to reset the alarm or anything?
