Smart Lock

If you see a flashing white light on your Smart Lock or Smart Lock Series 2, that indicates that the device’s battery is low. To clear this light, you will need to replace the device’s batteries.

For more information on replacing the Smart Lock’s batteries, see the How to Replace Smart Lock Batteries article in our Help Center. For details on replacing the batteries in the Smart Lock Series 2, see the How to Replace Smart Lock Series 2 Batteries article.

All features of the Smart Lock will still work without an Entry Sensor. 

However, the Auto-Lock feature on your Smart Lock will be “smarter” when the device is paired with an Entry Sensor. The Entry Sensor tells your Smart Lock when your door is open, preventing the Smart Lock from trying to lock your door when it’s open. 

For example, if you set your Smart Lock to Auto-Lock after 30 seconds but purposefully left your door open while bringing in groceries, your Smart Lock will not try to lock itself. 

We recommend putting an Entry Sensor on the same door as your Smart Lock to defend your door, and we recommend pairing the two devices to prevent Auto-Lock from engaging while the door is open.

If you purchased a Smart Lock from SimpliSafe® or an authorized retailer after October 2024, it is likely that you have the Smart Lock Series 2. 

You can also tell which version of the Smart Lock you have by looking at the shape of the device. The Smart Lock is a long oval with a height of 7.5 inches, while the Smart Lock Series 2 is a rectangle with rounded corners, and is 7.6 inches high.

See the image below for a side-by-side comparison between the two Smart Locks.

Pairing your Smart Lock and PIN Pad ensures that your Smart Lock will be responsive when you use it to lock or unlock your Smart Lock. You can pair your Smart Lock and PIN Pad together using either the Keypad or the Smart Lock itself. 

Yes, Amazon Alexa and Google Assistant can be used to arm your system which will automatically lock your door when Smart Lock is installed. However, commands to unlock your Smart Lock will not work - for security reasons. Unlocking your door must be done through the SimpliSafe® Mobile App, the PIN Pad, Keypad, or manually using your key on the deadbolt.
