Lockwood 3772-DXKOKITSC Key Override DX Digital Conversion Kit for Selector 3772 Mortice Locks
The Lockwood 3772-DXKOKITSC is a mechanical Digital DX key override conversion kit designed for compatible Lockwood Selector 3772 mortice lock applications. It provides keypad entry without batteries or electrical wiring, while still allowing keyed access when the correct lower cylinder arrangement is specified.
This product is not a complete mortice lockset. It is a conversion kit only and must be paired with a compatible Lockwood Selector 3772 series primary mortice lock. Door furniture and cylinders are also separate items and must be ordered to suit the intended application.
The 3772 DX key override format is commonly used where a mechanical keypad is preferred for commercial access control, but key entry is still required for authorised personnel such as maintenance staff, managers or master key holders.

This is a DX digital key override conversion kit only. It does not include the primary 3772 mortice lock, the 570E type key override cylinder, or Lockwood 1800 / 2800 series furniture. These items must be ordered separately.

Fire Door Compliance
The 3772-DXKOKITSC should not be described as a standalone fire-rated product. It is a DX key override conversion kit used with the Lockwood Selector 3770 series mortice lock platform, so any fire claim must relate to the complete doorset.
Lockwood states that Selector 3770 series cylinder mortice locks have been successfully tested on fire door assemblies for up to 4 hours, depending on the type of doorset and full hardware configuration. For DX fire door applications, the rubber mounting pad must not be fitted.

No. The 570E type key override cylinder must be ordered separately. - Does it require batteries or wiring?
No. This is a fully mechanical keypad system. - How is the code changed?

Additional Information
- Kit-Only Product:
This SKU should not be sold as a complete lockset. It is a DX keypad conversion kit for compatible Selector 3772 mortice lock applications. - Backset Selection:
The broader 3772 DX key override family covers 60 mm, 89 mm and 127 mm backsets through the related 3772DXKO, 4772DXKO and 5772DXKO lock families. - Single Code System:
This is a mechanical shared-code solution. It does not provide multiple user codes, audit trail or remote access. - Holdback Applications:
A key operated holdback function is available as a lock setting, but it requires inclusion of an internal cylinder. - Door Preparation:
Accurate fixing, spindle alignment and lock preparation are important. This is not a casual retrofit item. - Fire Door Context:
The underlying Selector 3770 series has been successfully tested on fire door assemblies, but compliance depends on the complete doorset and the relevant fire door manufacturer requirements.
