SimpliSafe's Smart Lock installation guides cover the Series 2 and the original lock, and setup happens in the app. Add the lock through the Overview page menu, Add Device or Camera, then Smart Lock, and follow the prompts, which include mounting and a calibration stage where the lock learns your door. The reset article notes common setup faults: getting stuck at calibration, a lock that will not calibrate or is not responding, or Error 142, which means the lock is linked to two different Base Stations.
The checks in more detail
Fix them by resetting the lock: unpair it in the app, power cycle by removing one battery for thirty seconds, hold the pairing button above the batteries for twenty seconds until all three lights flash, then add it again. Make sure the door is aligned, the deadbolt moves freely and the Base Station is within range, since range and interference affect pairing. Fresh batteries help calibration. If you hear Smart Lock Not Responding, follow the not responding article.
The lock uses SimpliSafe's radio link, so wifi is not involved. Test lock and unlock from the app and PIN Pad afterwards. Keep a key in your pocket during installation in case the bolt jams. If calibration fails repeatedly, the door rubbing on its frame is the usual cause. Install when you are not rushed and the door is in good order. Calibration works best when the door is closed and the bolt has room to move, so close the door firmly and check nothing presses on it before you start.
A lock installed on a door that swells in summer can calibrate in winter and fail in July, so if problems begin with the season, recalibrate after adjusting the strike plate rather than replacing the lock. Have the Release Tool from the box handy before you start, because you may need to open the PIN Pad during setup and forgetting where the tool went is a common delay.
Differential
Likely causes of “SimpliSafe Smart Lock Series 2 will not complete setup or pairing”, and how to tell them apart
- 1
A sticking door or bolt
What separates it Calibration fails because the door or bolt sticks and does not move freely
How to confirm Fix the door's alignment first, so that the bolt moves smoothly, then run the calibration again
- 2
Linked to two Base Stations
What separates it The app shows Error 142 because the lock is linked to two Base Stations
How to confirm Reset the lock and add it to only one system, so that it is not linked to both
- 3
Weak batteries
What separates it Setup stalls because the batteries in the lock are weak
How to confirm Fit four fresh AA batteries, then start the setup again from the beginning
- 4
Range
What separates it The lock will not pair because it is too far from the Base Station
How to confirm Move the Base Station closer to the lock during setup, then move it back afterwards if needed
- 5
An interrupted setup
What separates it The lock is stuck partway through because the setup was interrupted
How to confirm Unpair the lock in the app, reset it and start the setup again, following the prompts
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which stage of the setup the lock reached
- The error number shown in the app, if there is one

Reset if stuck
ReversibleReset it if it is stuck, by unpairing, power cycling and holding the pairing button for twenty seconds.
Add it again
ReversibleAdd it again after the reset, going through the same steps in the app from the beginning.
Test lock and unlock
