Ford B-Max Ignition Lock Cylinder Switch Keyless Lock Module 8V21-3K772-AE

Ford B-Max Ignition Lock Cylinder Switch Keyless Lock Module is an original component from the Locks and latches group, designed for the ignition system and steering column lock in this model. It ensures the consistent operation of the mechanical ignition lock cylinder with the electronic immobilizer, which translates into safe vehicle starting and access control. This solution allows for restoring the proper operation of the ignition system after a failure or damage to the factory lock.

Purpose and function in the vehicle

The presented ignition lock cylinder with immobilizer and steering lock is dedicated to the security system in the Ford B-Max. The component is responsible for the interaction between the mechanical key and the electronic authorization system, as well as for locking the steering column after the key is removed. Thanks to this, the ignition system operates in a predictable manner, and the vehicle remains properly secured against unauthorized use. A solution of this type is particularly important in the case of problems with starting the engine, the key getting stuck in the ignition, or improper steering wheel unlocking. Using an original Ford component allows for maintaining compatibility with the vehicle's factory electrical and mechanical architecture.

Construction and integration with the security system

The ignition lock cylinder immobilizer with steering lock is an integrated module that combines a mechanical part with elements that cooperate with the electronic system. The mechanical part is responsible for the physical positions of the key (lock, ignition, start), while the part associated with the immobilizer interacts with the vehicle's electronics, enabling key authorization. Such a combination ensures:

• consistent operation of the steering lock with key positions,
• proper communication with the immobilizer system,
• stable operation of the starting system in daily use. Thanks to maintaining the factory design, the module fits well into the existing steering column system without the need for interference with basic mounting elements.

Benefits of using an original Ford component

Using an original ignition lock cylinder immobilizer with steering lock in a Ford B-Max allows for maintaining the consistency of the entire security system. The element comes from the vehicle manufacturer's line, which promotes proper fitment to the steering column and compatibility with factory electronics. For the user, this means reducing the risk of problems with key matching, immobilizer errors, or improper steering lock operation. The product in used condition represents a reasonable compromise between the cost of repair and maintaining the original vehicle specification. In many cases, it is an effective solution when replacing a damaged ignition switch, especially when one wants to maintain factory build quality and design.

Part selection by numbers and vehicle integration

The ignition lock cylinder immobilizer with steering lock has an OEM part number and associated replacement numbers, which facilitates precise identification and selection for a specific Ford B-Max configuration. When matching, it is worth paying attention to compliance with the manufacturer's markings as well as the year and equipment version of the vehicle. This allows for avoiding assembly problems and ensures proper cooperation with the existing electronic system. For users who value the technical correctness of the repair, it is important that the element comes from the group of original Ford components, which helps maintain predictable operating parameters of the ignition and immobilizer system.

Condition, service application, and system expansion

The offered ignition lock cylinder immobilizer with steering lock is a used element, intended mainly for service applications – replacing a damaged or worn module in a Ford B-Max. This type of component is particularly useful for repairs related to problems with starting, steering lock, or improper operation of the security system. If you are planning a comprehensive repair or upgrade of the security zone and steering column lock in your Ford and need other elements from the same group, such as locking mechanisms, door lock cylinders, or latching elements, check the available parts in the Ford Locks and latches category. Additionally, if you are interested in a broader context of using original used components in premium segment vehicles, it is worth reading an article describing procedures for selecting parts by OEM numbers and practical examples of their application: BMW – sports performance and precision.
