Yale YDM4109A

Yale YDM4109A

A connected generation of Yale’s fingerprint mortise format. YDM4109A offers biometric and code entry alongside a mechanical-key override, using a familiar lever arrangement. It is a separate current A-series listing from the earlier YDM4109 already in the Smartify catalogue. The model is relevant where the homeowner wants app capability through the specified Yale accessories while keeping fingerprint and keypad access at the door.

Everyday access

Supported access methods: fingerprint; PIN; mechanical key; Yale Home app with kit. Choose the methods that fit the people using this doorway, then demonstrate them during installation. Digital credentials are most useful when residents understand both everyday operation and the backup procedure for their particular lock.

Key features and specifications

• Door thickness: 38–80 mm (specification table; survey required)
• Backset: 60 mm
• Battery: AA alkaline batteries
• Emergency power: External 9 V battery

Compatibility and installation

A compatible Yale Home module and Wi-Fi bridge are required for the applicable connected functions. The page’s thickness prose differs from its table; the 38–80 mm table range is subject to installation-template confirmation. Do not assume existing YDM4109 cut-outs match.

For a replacement project, send photographs of both door faces, the door edge and the frame. Include the thickness, current lock model and the access methods your household wants. These details help distinguish a suitable replacement from a door that needs preparation work.

Set up for the household

Set up the owner account and any required accessories during commissioning, then test the intended local and remote functions separately. Give each regular user an appropriate credential and review access when household arrangements change.

Frequently asked questions

Will it fit my existing door?

A model name and door thickness are not enough to confirm fit. The installer also needs to check the mounting template, available clearances, strike position and the condition of the door and frame. Complete that assessment before modifying the door.

What should be confirmed before ordering?

Confirm the exact Indian-market model, finish, package contents and installation scope. Any required connectivity hardware or optional accessories should be identified in the quotation. Share your preferred access methods so the supplied configuration can be checked against them.
