The Yale Assure Lock SL is a slim, retrofit smart deadbolt designed for keyless entry via a backlit touchscreen keypad, with optional Wi-Fi and Bluetooth modules for app control. It features auto-unlock capabilities and compatibility with major voice assistants, offering a tamper-proof security solution. However, the need to purchase separate modules for full remote functionality is a significant drawback for some users.

The Yale Code is a standalone, non-smart keyless entry system designed for users who prioritize simplicity and reliability over smart features. It offers robust Grade 2 security and easy PIN management but lacks modern conveniences like auto-locking or app integration. It is best suited for homeowners who want keyless entry without the complexity of smart-home ecosystems.
