Additional useful information
Use this Scanual guide to identify Yale Assure Lock 2 Key-Free Touchscreen Family, follow official setup and reset guidance, and match power, radio, mounting, hub, and regional accessories to model YRD450.
Yale YRD450 is the key-free touchscreen Assure Lock 2 root family; Bluetooth, Wi-Fi, Z-Wave, and Touch fingerprint behavior depends on the complete suffix, especially the YRD450-F distinction.
Setup: Measure and install the key-free touchscreen and DoorSense, add four AA cells, self-hand while unlocked, then add in Yale Access and configure only the radio or fingerprint hardware confirmed by the full suffix.
Reset: Use the Yale Access owner reset path where available and the physical YRD450 procedure. Re-handing, codes, DoorSense, network module, and fingerprint enrollment must be rebuilt as applicable.
Troubleshooting: Use the 9V contacts only for temporary entry after battery failure. Correct strike and bolt alignment, replace all AA cells, re-hand, and read the complete suffix before Wi-Fi, Z-Wave, or fingerprint diagnosis.
Compatibility and ecosystem boundary: YRD450 without -F identifies the key-free touchscreen base, not guaranteed fingerprint hardware. YRD450-F is Touch/fingerprint; YRD450-N is Plus/Home Key and has separate module compatibility.
Maintenance and accessory matching: Use four alkaline cells and exact suffix-fit exterior and module parts. Record F, N, BLE, WF1, or Z-Wave markings before recommending any accessory or ecosystem path.
