Using an original component from the Ignition Accessories group allows for maintaining the consistency of the security system and operational ergonomics. In practice, this means:

• maintaining the factory operation of the steering lock after removing the key,
• proper cooperation with the electrical installation and ignition system,
• no need for mechanical modifications to the steering column,
• reducing the risk of communication errors in vehicle systems resulting from non-original solutions.

For the user, this means predictable operation of the ignition system, convenient key handling, and the preservation of safety standards provided by the vehicle manufacturer.

Component condition and installation aspects

The offered ignition switch with steering lock is a used component, which allows for an economical repair while maintaining the original design. Before installation, standard verification by a mechanic is recommended, including checking the operation of the locking mechanism and the correctness of electrical connections after installation in the vehicle.

Replacing this component is a typical service operation within the steering column and ignition system. A correctly selected component facilitates the restoration of full ignition switch functionality, which is important both from the point of view of safety and daily vehicle operation.

Vehicle fitment and identification parameters

To correctly select an ignition switch with steering lock for a specific Volkswagen vehicle, it is crucial to compare the part's identification data and interchangeable numbers with the vehicle's specifications. For this purpose, it is worth using information from the technical specification list, the VIN number, and service documentation, which minimizes the risk of purchasing an unsuitable component.

Designations such as SKU, OEM Part Number, available interchangeable numbers, as well as Make and Condition are presented in the product's technical specification section and form the basis for verifying compatibility with a specific Caddy Maxi or Golf Mk5 model.
