The smart deadbolt invites you to a more convenient entry experience. As an upgraded version of the electronic deadbolt, it retains and improves all features of the former and provides more thoughtful features for your easy life. Choose the unlock method that fits your lifestyle the moment you arrive home. You can choose from unlocking with your fingerprint, PIN codes, keys, or just unlock the door with a gentle touch of the Philips Home Access app on your smartphone.
