Lock the door. Unlock it to turn it off and reset it if it's triggered.

If you have an owner's manual, I suggest you read it first.

After that, this may help troubleshoot any problems you are having.

i used to have the problem where if i locked my doors and used the key to unlock them then got in and drove around without manually unlocking the door from the inside and opened the door that the alarm would go off....
