  Call your alarm company's alarm receiving center. The company will ask you some questions to verify that you are who you say you are. They will ask you about the alarm you're calling about to reset, and they will then request the reset code that you wrote down. If the company doesn't need to send an engineer out to check your system and reset it, they will tell you an "Anti Code."
