Our tips to prolong the life span of your digital lock:

1) Use only ALKALINE batteries (recommended Energizer)

2) Do not use rechargeable batteries or mix new batteries with old batteries

3) Change batteries after 6 months to prevent batteries leakage

4) Install door closer to prevent your door from slamming, otherwise, warranty will be void
