Whilst many fingerprint locks require the use of wifi or bluetooth in order to work, the Blusafe Breeze system does not. The fingerprint technology in the lock is battery operated and has no connection to the internet. Therefore the lock will work regardless of a power cut or the loss of internet.
If the batteries die, you are still provided with a manual backup key so you won’t be locked out. We do recommend changing the batteries every 6 months, depending on how frequently you use the lock, to prevent the use of the backup key.
