Purpose and function in the vehicle

The presented item belongs to the Ignition sets group and is responsible for the interaction between the steering column, mechanical lock, and the ignition system in the Ford Focus Mk3. A correctly selected set of this type is crucial for:

• ensuring proper steering wheel locking after removing the key,
• stable operation of the ignition switch mechanism during startup,
• maintaining consistency between the key/fob and the ignition system.

By using a solution compliant with Ford's factory specifications, the system maintains proper geometry and interaction with the steering column, which reduces the risk of additional stress and accelerated wear of components.

Technical characteristics and compatibility

As a Ford brand product, the set has been designed to maintain the factory operating parameters of the ignition system in the Focus Mk3. It includes an integrated steering lock mechanism and an ignition cylinder that works with a dedicated key/fob. This combination facilitates matching to a specific vehicle configuration and minimizes installation issues.

The item has an assigned OEM part number and associated interchangeable numbers, which allows for precise verification of compatibility with a specific equipment version. When selecting, it is worth comparing the markings with the currently installed component or service documentation to avoid mechanical or electrical incompatibility.

Technical condition and service application

The offered set is classified as for parts or not working, which means it is treated primarily as a parts base or material for regeneration, rather than a ready-to-use, fully functional component. It can serve as a source of mechanical elements, housings, inserts, or auxiliary components for specialized workshops dealing with the repair of ignition systems and steering locks.

This solution is particularly useful when hard-to-find parts of the mechanism are needed or when a professional rebuild of an existing ignition switch is planned while maintaining the original key and vehicle configuration. Before installation in a vehicle, detailed diagnostics and potential regeneration by an experienced service center are recommended.

Benefits of using an original ignition set

Choosing an item from the Ford Ignition sets group brings a number of practical service advantages:

• preservation of the factory design and fitment for the Focus Mk3 steering column,
• possibility of using components in the repair or regeneration process,
• easier identification thanks to the original manufacturer's marking,
• consistency with solutions used in authorized service procedures.

For workshops specializing in automotive electronics and mechanics, such a component constitutes a valuable base for rebuilding ignition systems, especially in cases of mechanical damage, theft attempts, or operational wear.
