Troubleshooting eufy FamiLock E35 common problems and fixes

Lock does not respond: Check that the main battery is charged and the backup battery is seated correctly. If the lock is unresponsive, charge the primary battery fully before retrying.
Palm recognition fails: Re-register the palm, keep the hand centered and close to the sensor, and make sure the sensor window is clean and dry.
Wi-Fi connection drops: Verify router signal strength at the door, restart the lock and router, and reconnect through the eufy app if needed.
Door does not lock smoothly: Check alignment between the deadbolt and strike plate; small door shifts are a common cause of friction or jammed locking.
Error codes: If the app or lock displays a setup or connectivity error, follow the in-app prompt, re-pair the device, and confirm firmware is current.
Preventive measures: Keep the sensor clean, update firmware regularly, avoid exposing the lock to direct water spray, and test the backup battery during routine maintenance.

If issues continue, use the eufy Support Center for manuals, FAQs, and service guidance. eufy also offers professional support through phone, email, and live chat, and warranty coverage for the lock typically includes electronic and mechanical protection periods that vary by region and seller.
