Simplisafe Smart Lock PIN Pad Batteries

It looks like both the indoor unit and the PIN pad have their own batteries.  How do I replace the batteries on the PIN pad and what type of batteries do they use?  How long do the batteries last on the indoor unit as well as the PIN pad on the outside?

Hi abcd,

The Smart Lock uses AA alkaline batteries, and those last about 8-12 months. The PIN Pad uses CR2450 Lithium (one of those flat watch batteries), and depending on use should last about 3 years.
