Additional useful information
Use this Scanual guide to identify Yale Assure Lock 2 Touchscreen (Keyed), follow official setup and reset guidance, and match power, radio, mounting, hub, and regional accessories to model YRD420.
Yale YRD420 is the keyed touchscreen Assure Lock 2 family with Bluetooth, four-AA power, DoorSense, and package-suffix choices for Wi-Fi, Z-Wave, or other supported modules.
Setup: Install the keyed touchscreen, cable, DoorSense, and four AA cells, self-hand with the bolt unlocked, add the lock over Bluetooth, and configure only the module identified by the complete suffix.
Reset: Remove or reset through Yale Access when authorized, then perform the YRD420 physical reset. Re-hand and rebuild codes, DoorSense, network module, and hub or app relationships.
Troubleshooting: Check strike alignment, bolt travel, cable, battery pack, and handing before electronics. For connectivity, distinguish base YRD420-BLE from WF1 and regional Z-Wave packages or YRD420-F fingerprint variants.
Compatibility and ecosystem boundary: YRD420 is the keyed touchscreen root family. YRD420-F adds the Touch fingerprint identity, while YRD450 is key-free; accessories and modules must list the exact suffix.
Maintenance and accessory matching: Use four matched alkaline cells and keyed YRD420 fit parts. Capture the full suffix and finish before selecting modules, exterior assemblies, latches, or replacement interiors.

Setup: install, self-hand unlocked, add in Yale Access, then provision module. Reset: app and physical sequence erase codes, users, handing, and network state.
