Key pad wont "Quit" after Install of Devices???

Cant you just exit out of everything or no?

Ugh, sorry that happened to you.  Once your devices are installed (in your case, re-installed :), use the left arrow button on the keypad and keep pressing it until you see the "Exit" word, then press it, it will turn the system to off and the base station will announce "Simplisafe, Off."

If you have the interactive monitoring plan, you can also add your devices from your online control panel, under the Devices section.  I believe you still have to pair them by pressing the buttons on the sensors and components, but you can click the "save changes" button when done (this will sync everything to the base station).  Please write down all your serial numbers first, you'll need them when entering them via the online control panel - it's always a good idea to have a written list of them anyway, to keep handy in the home.
