Yale Locks R-YRD256-NR-619 Assure Lock SL Satin Nickel door lock

Yale Assure Lock SL Deadbolt

The Yale Assure Lock SL R-YRD256-NR-619 is a satin nickel deadbolt that replaces a traditional keyed cylinder with a slim backlit touchscreen keypad. Users unlock the door by entering a personal code and can lock it again with a single tap or by enabling the Auto Relock function. Two physical keys are included for backup access. The lock fits standard doors and is designed for homeowners who want keyless entry without a bulky exterior escutcheon.

Check door thickness and smart-home plans

Verify that your door is between 1-3/4 inches and 2-1/4 inches thick so the supplied hardware aligns correctly. Confirm you have a standard deadbolt cutout because the lock installs with only a screwdriver in minutes. Decide whether you want smart-home integration now or later; the lock accepts an optional Yale network module for Z-Wave or Zigbee connectivity, but the module is not included in the set.

Build quality and daily use

The satin nickel finish resists tarnish and matches common door hardware while the slim profile reduces the chance of catching on clothing or bags. A backlit touchscreen remains readable in low light and wipes clean easily. Four AA alkaline batteries are included and power the lock for typical household traffic; the battery compartment is accessible from the interior side for straightforward replacement. The included BILT app provides interactive installation guidance.
