How to disable alarm.

My 2006 RAV has a problem. My remote is occasionally not working. I have replaced the battery. Still inconsistent. If I lock the door remotely then find that I cannot open it remotely I put the key in the lock and open it. Problem: that triggers the alarm which wakes all the neighbours and keeps going up wards of 30 seconds.


Question one.      If I trigger the alarm, what can I do to stop it immediately?


Question two.  Can I permanently disable the alarm? If so, how?

I really hope someone is here to help.
