SimpliSafe's Smart Lock reset article has four steps. First unpair: in the app choose My System, Device Settings, pick the lock, scroll to the bottom and tap Remove Device. Second, power cycle: slide the battery cover off (up for the original lock, to the right for the Series 2), remove one battery and leave it out for thirty seconds, then put it back without replacing the cover.
The checks in more detail
Third, factory reset: press and hold the pairing button above the batteries for twenty seconds, and when all three lights flash together the reset is done; if no lights appear, make sure all four batteries are seated or replace them with new Duracell AA cells. Then slide the cover back. Fourth, reinstall: on the Overview page open the menu, choose Add Device or Camera and Smart Lock, and follow the prompts. Use a reset when the lock will not calibrate, is not responding or shows Error 142, meaning it is linked to two Base Stations.
Before resetting, note your PINs and settings since they return to defaults, and keep a key handy. If you are selling the property, remove the lock from your account. Contact support if it will not reset. Photograph your PIN list before resetting and store it somewhere safe. After a reset give the lock a moment before adding it. Avoid resetting when you cannot open the door another way.
Do not skip the thirty-second battery-out step, since it is what lets the lock clear its previous pairing before the factory reset. If the lock will not reset after four fresh batteries and the full twenty-second hold, note exactly which lights appeared and which did not, since that description is the most useful thing you can give SimpliSafe support. After the reset add the lock and test it three times, locking and unlocking by app and by PIN Pad, so you know the reset really cleared the fault.
