Yale Approach
Score: 72/100Rankings

The Yale Assure SL is a versatile smart deadbolt featuring built-in Wi-Fi and a touchscreen keypad, ideal for retrofitting standard doors. Its main drawback is the reliance on disposable AA batteries which require frequent replacement. It is best suited for homeowners who want immediate remote access without purchasing additional connectivity hubs.

The Yale Approach Smart Wi-Fi Deadbolt is a renter-friendly retrofit lock that offers easy installation and robust smart home integration without altering exterior hardware. Its main trade-off is the dependency on a separate Wi-Fi bridge and the optional nature of the keypad. It is best suited for renters or users who want to preserve their existing deadbolt hardware while adding remote access.
