Yale Assure Lock SL Key-Free Deadbolt

The Yale Assure Lock SL (YRD256 series) is an electronic, key-free motorised touchscreen deadbolt designed for residential timber doors. According to Yale Home Australia, the unit features a zinc casing and fits standard Australian door preparations with a 54 mm face bore, a 25 mm latch hole, an adjustable backset of 60 mm or 70 mm, and door thicknesses between 35 mm and 57 mm. It runs on four AA alkaline batteries and uses a backlit touchscreen for four-to-eight-digit PIN codes. The retail bundle includes the Yale Home module and a DoorSense sensor to track door open and closed states. Because the lock lacks a physical keyhole entirely, Yale includes external 9V battery terminals on the underside of the keypad to supply emergency power if the internal batteries deplete.

Who it suits

This deadbolt suits homeowners wanting to replace a mechanical deadbolt with a keypad and eliminate physical brass keys. It is particularly practical for Apple households, as the included Yale Home Bluetooth module connects natively to Apple Home without extra hardware. It also works well for households managing guest access, as temporary PIN codes and activity tracking are managed directly within the Yale Home app without any paid subscription.

Conversely, households that require a traditional mechanical keyway for peace of mind should look elsewhere. Yale notes that secondary entrance access is recommended because there is no manual override key if the electronics fail. Renters should also pause before buying: replacing door hardware generally alters the rental premises, so consult your state or territory residential tenancy authority and obtain landlord approval before replacing existing door locks.

Australian notes

Because the lock is battery-operated, it requires no mains connection or electrical work. However, buyers should note that Wi-Fi is not built into the lock hardware. Out of the box, smart operation is restricted to local Bluetooth range. To enable remote unlocking, notifications away from home, or integration with Google Home and Amazon Alexa, an optional Yale Connect Wi-Fi bridge is required. According to Yale support, the legacy Yale Connect Bridge requires a 2.4 GHz Wi-Fi network, whereas the Yale Connect Plus Bridge supports both 2.4 GHz and 5 GHz networks. Matter is not supported on Australian YRD256 models. In Australia, Yale provides a 3-year warranty covering electronic and electromechanical components, though damage caused by coastal salt spray corrosion is excluded.
