Help with Home Security Alarm System

So I changed the battery of my home alarm system and it's acting like this. The previous code does not seem to work. Can anyone help me with this, to reset the code and to stop it the way it is acting or is there any default code for it?


  • Is there a master password or reset switch in the junction box for the alarm?

    • Hi, I could not find anything similar, have tried so many things found on internet but nothing seems to work..

  • Who installed it? Call them up and see if they have records of the master code. If it is a rental, get the agent to sort it out.

  • It appears (from a Google search) that when you replace the battery, you may need to enter the master code to get it running again. Do you have the manual?
