    Smart Lock Installation in Sunnyvale

    Smart locks are popular in Sunnyvale's tech-forward household market. A licensed locksmith can advise on compatibility with your existing door prep and recommend brands based on your connectivity needs. Key considerations for Sunnyvale homes:

    Wi-Fi vs Bluetooth

    Wi-Fi locks allow remote access from anywhere but require your router to be active. Bluetooth locks work from a few feet away without Wi-Fi but lack remote control.

    Battery Life

    Most smart locks use AA batteries and last 6-12 months. Schlage Encode and Yale Assure have strong battery performance records in customer reviews.

    Door Prep

    Standard US door prep (2-3/8" or 2-3/4" backset) works with most smart locks. Mortise-style locks on older Sunnyvale homes may need adapter hardware.

    Physical Key Backup

    All major smart lock brands retain a physical keyway as backup. Confirm your locksmith programs the app AND provides physical keys tested in both positions.
