Check your door first
Door material, thickness, frame and existing lock cut-outs affect compatibility. Share photographs and measurements with the installer before selecting a model.
Choose access that suits you
Depending on the model, options may include a PIN, fingerprint, card or app. Check the exact features and how access is managed for family members or visitors.
Understand backup access
Ask about low-battery alerts, emergency power and mechanical key access where available. Learn how to change batteries and remove old users after installation.
