Hello Adam,
We appreciate your feedback and your experience with our products is very important to us. Please know that a fresh set of name-brand alkaline batteries should last up to 6-12 months in the lock, depending on usage. Do not use lithium or rechargeable. Our electronic locks are intended for installation on a door where the lock's interior is enclosed and protected from the outside elements. The touchscreen can face the exterior and withstand rain, sun, and snow. The full lock is not weatherproof and cannot be installed on a door with no covering. We also have a team of lock experts here to assist you with anything from installation, to troubleshooting, to warranty support when needed. Should you need assistance, we ask that you please call our Support Team at 1-800-327-5625.
Thank you,
Kwikset
