Having already mounted Nuki Smart Lock 3.0, can frequent use of the physical key be detrimental to the electronic lock mechanism? Do you have any experience with this? Thank you!
The Smart Lock has a clutch which disconnects the drivetrain from the cylinder/key when the motor does not turn. Therefore the frequency of physical unlocks has no impact on the Smart Lock.
IT is the other way around.
Depending on your cylinder, frequent use of the external physical key with the Nuki installed (internal physical key inserted) could end breaking the cylinder.
With mine I have to push the key harder to ensure the mechanism is pushed correctly when entering with key. Or use the Nuki, which I prefer of course.
