Product Overview
A locking key or drive plate engages a mating profile to transfer or restrain movement.
This catalog entry concerns an internal mechanism part rather than a cut door key.
Structure & Mating Interfaces
Provide the central connection, working profile and angular travel.
Identify whether the part transmits rotation, indexes a position or locks another member.
Engineering Focus
Why distinguish an internal drive key from a door key?
The internal part is defined by its relationship to the mechanism, whereas an external key has a different scope and interface.
Naming the supplied component precisely avoids ambiguity over profiles, mating hardware and what the quotation actually includes.
Manufacturing Route & Finishing
Compare profile forming and machining with final control of engaging edges.
Functional profiles should not be rounded unintentionally during finishing.
The proposed route is confirmed for your drawing, material and quantity. An image does not establish a fixed tolerance or a complete process specification.
Compare manufacturing capabilities →Materials & Surface Requirements
Specify the base material, final condition and corrosion or appearance requirements.
Mark drive, guiding and contact surfaces that must meet their dimensions after treatment.
The component specification does not establish a security rating for the complete lock.
Review material-selection information →Quality & Sample Approval
Check engagement, orientation and clearance against the mating mechanism.
Evaluate the agreed locking and release sequence.
Specify the drawing revision and the condition in which each dimension is inspected. Record the agreed dimensional and functional checks before sample approval.
Quality documentation →Prepare a Product-Specific RFQ
- Component definition. Send the 2D drawing and 3D model, where available, with the drawing revision and the requested part or assembly scope.
- Mating information. Include the assembly references needed to define the interfaces discussed above.
- Delivered condition. State material, finishing and inspection requirements, identifying any items that need a manufacturing recommendation.
- Supply plan. Include sample needs, expected order and annual quantities, packaging requirements and target timing.
Product Questions
Is this an externally cut key for a particular lock brand?
No. It is a custom internal drive-component reference; the required profile must come from the customer's drawing.

How should the completed mechanism be checked?
Check engagement, orientation and clearance against the mating mechanism. Evaluate the agreed locking and release sequence.
Technical Context
The product-specific notes above identify drawing-review questions. General process and material references are collected separately; they do not verify a material grade, production qualification or performance claim for the pictured part.
