Shipping From:

When ordering multiple Keyed Alike locks, only 1 set of keys are provided as all additional locks are made to work from that key.

If ordering 4 or more keyed alike locks you can have them set up as different groups. If Required: Let us know the details in the "Specific Key Requirements" field above.

Each group of locks will then receive keys.

Latch & Deadbolt

The Yale Doormaster Mila-style Repair Gearbox is listed as YDM-GBM1LAD-35T, a 35mm single-follower latch and deadbolt centre case.

Match the reference on the supplied part to the particular existing Mila mechanism. Compare the follower, backset, case fixings, latch/deadbolt layout and drive connections; the Mila name and 35mm/92mm measurements alone do not establish fit.

Check whether the existing mechanism uses offset or inline connectors before fitting. Do not slot, reshape or otherwise adapt a drive connection without instructions approving that exact donor and replacement. The fixing method and latch handing must also follow the supplied case instructions.

This is a gearbox-only repair component, not a full locking strip or a general conversion for older Mila locks.

FAQs

Identify the exact donor case and compare its follower, backset, 92mm centres, fixings and drive connections with the supplied replacement. The description 'old-style Mila' and the headline measurements are not a complete compatibility check.

The latch is listed as reversible. Follow the instructions for the supplied case and confirm the required orientation and complete lock handing rather than using a generic screw-removal procedure.

This is the listed single-follower, lever-operated repair family. Use the operating instructions for the matched complete lock and furniture; confirm the cylinder and latch actions for that assembly.

Confirm the fixing method and screws from the exact supplied case instructions. Check offset versus inline connectors before fitting; do not assume they are interchangeable or modify a drive gear without approval for that precise donor and replacement.
