There comes a time in every security professionals career where either an installer code was lost, changed, locked out, or forgotten.
An installer code is a 4 digit code that, when entered into the keypad, will allow you into the programming menus of an alarm panel.
Some panels however have back doors hidden in them that allow access to the installer menu without ever knowing the code. Take the Honeywell Lynx Touch L5100 for example.
This beauty is actually one of my favorite alarm panels to work with (only being beaten by the Lynx Touch L7000 of course) combining a whole hefty set of features such as Z-Wave, Wifi, and GSM into a small easy to install package.
Quick tip for those of you using AVG Firewall. I ran into an issue where, after installing AVG, my VMWare virtual machine would not longer connect to the internet. Windows still showed a connection and I could still ping (both by IP and domain names), but when I open a browser to load a web page, nothing happened.
At first I didn’t realize it was AVG that was causing the issue (it’s been a while since I last used my VM so I didnt make the connection right away). But some simple troubleshooting narrowed it down (set firewall to “Allow All“) and boom, internet started working right away.
