Dormakaba 118-509978-K 1 EACH – Frequently Asked Questions

1) What exactly comes in the Dormakaba 118-509978-K part?
One battery holder plus the mounting screw, packaged together and sold as a single unit (1 each). It is a genuine Dormakaba replacement component, so you get the holder and the fastener in one order rather than sourcing the screw separately.
2) Will the 118-509978-K battery holder fit a non-Dormakaba lock?
No. It is a Dormakaba OEM component built to fit supported Dormakaba lock systems only. Battery holders are model-specific in shape and screw location, so match the part number against the Dormakaba lock you are servicing before ordering. Other brands' service parts, such as Corbin Russwin's ML2000 screw packs, are not interchangeable with it.
3) Our facility standardizes on Corbin Russwin mortise locks - does the Dormakaba 118-509978-K fit them?
No. The Dormakaba 118-509978-K is a genuine OEM part matched to supported Dormakaba hardware. For Corbin Russwin ML2000 mortise locks, the service parts are brand-specific: the 429F31 screw packet for the N escutcheon, the 433F77 pack for M and P escutcheons, the 425F86-8 flat screw, and the 206F57-8 strike combo screw. Match the part to the lock brand already hung on the door.
4) Can a Corbin Russwin ML2000 screw pack be used in place of the Dormakaba 118-509978-K?
No. The Dormakaba 118-509978-K supplies a battery holder together with its screw, so the part carries the battery-retention component, not just fasteners. The Corbin Russwin 429F31 and 433F77 are screw packs for ML2000 escutcheons - the 429F31 for the N escutcheon and the 433F77 for the M and P escutcheons - and contain fasteners only. They serve different hardware and are not interchangeable with the Dormakaba part.
5) Is the Dormakaba 118-509978-K battery holder meant for commercial doors or residential locks?
Commercial. It is catalogued for commercial door hardware service, and the typical settings are offices, schools, healthcare, retail, warehouses, multi-tenant residential buildings and municipal facilities. If you are servicing a residential-grade lock, this is not the part to order.
6) I only need a loose fastener for a commercial lock, not a whole assembly - what are the options?
If the need is a single fastener, the Corbin Russwin 425F86-8 is an 8-32 x 3/8 inch flat screw for ML2000 mortise locks, and the Corbin Russwin 206F57-8 is a combo screw for ML2000 strikes. The Dormakaba 118-509978-K is a different kind of order: it is a battery holder supplied with its screw, intended for servicing supported Dormakaba hardware rather than replacing a generic fastener.
7) How do I order multiples of the Dormakaba battery holder for a portfolio of doors?
It is sold as 1 each, one holder and screw per unit, so quantity maps straight to door count. A property manager standardizing service kits across a building orders one per opening being serviced, no pack-quantity math involved.
8) Is the 118-509978-K a lock part or just installation hardware?
It is an installation accessory that supports a mechanical lock assembly, not a lock or a working lock mechanism. It holds the battery in place and screws down; it does not change the lock's function, handing or keying.
