How To Replace Smart Lock Batteries

The Smart Lock is powered by 4 Duracell AA Alkaline batteries, and the PIN Pad takes 2 Duracell CR2450 Lithium batteries. The batteries within the Smart Lock and PIN Pad have a life expectancy of 8-12 months, depending on usage.

If your Smart Lock is still offline after replacing its batteries, skip to the section below for troubleshooting steps.

To change your Smart Lock batteries, follow the steps below:

1. Slide the battery cover (the oval portion of the Lock labeled "SimpliSafe") off the device by pushing up on it.

This will expose the batteries and allow you to replace them.

2. Once the batteries have been replaced, put the battery cover back on and slide the compartment up until it clicks into place.

To replace the PIN Pad batteries, follow the steps below:

1. Use the pinhole key that was included in your Smart Lock box and press the tool into the pinhole on the bottom of the PIN Pad

If you do not have the pinhole key still, a SIM Card tool or a paper clip may also work

2. Once the pinhole has been pressed, the top of the PIN Pad will pop off, and you will then be able to replace the batteries

3. After the batteries have been replaced, press the PIN Pad top back on until it clicks into place
