As an added layer of security, each Smart Lock can be paired to only one Base Station at a time. If you attempt to pair a Smart Lock to a system while it is already paired to another system, you may get Error 142.

If you have access to the previous Base Station the Smart Lock was paired to, you should unpair it using the SimpliSafe® Mobile App:

1. Open the SimpliSafe® Mobile App on your phone or tablet

2. Choose My System from the bottom navigation bar

3. Select Device Settings

4. Tap on your Smart Lock

5. Scroll down and choose X Remove Device

Once your Smart Lock has successfully unpaired, you can add it back to your system using the installation guide for Smart Lock or for Smart Lock Series 2. If you’re unsure which Smart Lock you have, you can learn more about the differences in our comparison guide.

If the previous Base Station is no longer available, you should reset the Smart Lock using the appropriate steps for Series 1 or Series 2. 

If you still see Error 142, we recommend contacting our Support team for additional help.
