ANN ARBOR, Mich – Although relatively new to Tree Town, technology startup PassiveBolt Inc has already gained traction for its innovative smart access module and its reimagining of keyless home entry. One of the first of its kind, the smart lock also freezes a door’s deadbolt when it senses an attempted security breach, like lock picking. Founded in 2018, Ann Arbor's PassiveBolt is introducing consumers to smart access. (PassiveBolt Inc)Maiga said that PassiveBolt’s first year was spent further developing its Shepherd Lock but when the COVID-19 pandemic hit things slowed down. It also intends to expand into other areas of keyless entry and smart access as time goes on.
