Any installation? How many ic card provided? When we need to change the battery? If the knob totally fail and cannot open at all, what is the next step yo do?
Installation $30. 3 card will be provided. The battery will last between 3 to 6 months, depending on frequency of usage daily. If the knob totally fail as in no battery, then change battery as battery compartment is on the outside. If knob fails totally, then hacking off the door knob will be required. We have another type of lock body that comes with master key and it will cost $50 more. We are in the middle of bringing that in.
