Weiser Kevo locks let you use your Bluetooth enabled iOS and Android devices to control the door lock. Forget fumbling with keys. Just touch the lock to lock or unlock as long as you have your phone with you. Keep track of who's locking and unlocking the door. Get notifications when your kids arrive home. Send a virtual e-key from anywhere to allow permanent or temporary access for a friend, family member, neighbour or worker. Kevo Plus works with many other partner products. Now compatible with Amazon Alexa devices.
