Brinks, Broadview, and Monitronics alarms are especially hard for other companies to re-use. However there are a number of fairly new cell/internet devices that you can wire up as if they were the phone line and they do dialer capture without the need to change phone or account numbers. Honeywell makes good products generally so don't hate on the brand entirely,
@smiticans and I were both just lamenting these wireless aio alarms. For some irony compare the prices for a honeywell tuxedo touch keypad to the Lynx 7000 seems like the tuxedo should cost less...
A more traditional panel like a Honeywell Vista 20P has some advantages: hardwired zones (including smoke detectors and co if you want), bigger battery backup, larger sirens can that can be installed in better locations, smashing the keypad doesn't matter, it's harder to find/disable the control panel, install multiple keypads, wireless receivers, serial automation modules that can integrate with real automation gear, the keypads are generally physically smaller and more attractive, and so on.
Master code != installer code
Master code is used to change / assign user codes and certain other functions like setting the time.
Installer code is used to access the programming menus
Cellular and Internet alarm communication protocols are faster than POTS, so someone smashing this type of alarm or cutting the wires going to it may get reported just don't expect the siren to go off for too long.
Hold the arm / disarm button until the light on the fob flashes and see if the panel does anything. If the light doesn't turn on get a new coin cell battery.
There are instructions in the installation manual I linked to to acquire the installer code if the panel isn't locked out.
Here's a video on programming keyfobs:
