  • Rechargeable batteries must not be used as they may damage the board and are not covered by warranty.

  • If rechargeable batteries were used, the inside panel must be replaced (customer to purchase). 🔗 Order replacement parts here: https://mysmartlocks.com.au/collections/spare-parts

2. Corrosion / Rust Check

  • Inspect batteries and terminals for corrosion or rust.

  • Corrosion/rust damage is not covered by warranty.
