Security you can trust. Two-factor authentication, biometric verification and matte keypads for fingerprint resistance provide extra peace of mind. So, you know only the right people have access at the right time. Never get locked out. Your lock is battery powered so you'll still have access during a power outage. Don't worry, it's locked. Never worry again about remembering to lock the door. Yale can be set to Auto-Lock once DoorSense detects that the door is closed. No professional installation needed. The lock replaces your deadbolt on most standard entry doors using just a screwdriver; no DIY experience required.
